Experimental
General Tetrahydrofuran toluene and NN-dimethylformamide were dried using a commercial
solvent purification system Dichloromethane was distilled from calcium hydride when used as a
reaction solvent All other solvents and reagents were used as received Compounds S11 S22 S33 and
S44 were prepared according to literature procedures 1H NMR spectra were recorded on high-field
spectrometers (1H frequency 50013 or 60013 MHz) equipped with broadband inverse gradient
probeheads Spectra were referenced to the residual solvent signals (chloroform-d 724 ppm) 13C
NMR spectra were recorded with 1H broadband decoupling and referenced to solvent signals
(13CDCl3 770 ppm) High resolution mass spectra were recorded using APCI or ESI ionization in the
positive mode
Computational methods Density functional theory (DFT) calculations were performed using
Gaussian 095 DFT geometry optimizations were carried out in unconstrained C1 symmetry using
molecular mechanics or semiempirical models as starting geometries X-ray geometries were used as
initial models for 3-Et and 4-Et DFT geometries were refined to meet standard convergence criteria
and the existence of a local minimum was verified by a normal mode frequency calculation DFT
calculations were performed using the hybrid functional B3LYP6ndash8 and the 6-31G(dp) basis set
Solvation effects were modeled using the IEFPCM formalism9 with standard solvent
parameterizations chloroform (1H and 13C NMR for 1ndash4-Et) dichloromethane (TD-DFT for 1ndash4-Et)
and NN-dimethylformamide (thermochemistry of the Yamamoto coupling) 1H and 13C shieldings
were calculated using the GIAO approach and referenced to the absolute TMS shieldings calculated
at the same level of theory (317454 ppm for 1H and 1920973 ppm for 13C) NICS scans were
performed with gas-phase calculated GIAO shieldings Electronic transitions were calculated by
means of time-dependent DFT (TD-DFT) All TD-DFT calculations were performed at the CAM-
B3LYP6-311+G(dp)6-31G(dp) level of theory10 using dichloromethane solvation
X-ray crystallography X-ray quality crystals were grown by slow diffusion of methanol into a toluene
solution of 3 same method was used to get crystals of 4 Diffraction measurements were performed
on a к-geometry Ruby PX diffractometer (ω scans) with graphite-monochromatized Mo Kα radiation
The data for 3 and 4 were collected at 100 K and 80 K respectively corrected for Lorenz and
polarization effects Data collection cell refinement data reduction and analysis were carried out
with the Xcalibur PX software CRYSALIS CCD and CRYSALIS RED respectively (Oxford Diffraction Ltd
Abignon England 2009) An analytical absorption correction was applied for the data of 3 and 4 with
use of CRYSALIS RED Both structures were solved by direct methods with the SHELXS-97 program
and refined using SHELXL-9711 with anisotropic thermal parameters for non-H atoms In the final
refinement cycles all H atoms were treated as riding atoms in geometrically optimized positions

Photoluminescence Photoluminescence excitation (PLE) spectra as well as decay kinetics (DEC) were
taken with the FSL980-sm Fluorescence Spectrometer from Edinburgh Instruments Ltd A 450 W
Xenon arc lamp (PL and PLE) and a Super Continuum Fianium laser were used as excitation sources
Emission spectra were corrected for the recording system efficiency and excitation spectra were
corrected for the incident light intensity The quantum yield measurements were performed by using
an Edinburgh Instruments integrating sphere equipped with a small elliptical mirror and a baffle plate
for beam steering and shielding against directly detected light For the measurement the integrating

Experimental
General Tetrahydrofuran toluene and NN-dimethylformamide were dried using a commercial
solvent purification system Dichloromethane was distilled from calcium hydride when used as a
reaction solvent All other solvents and reagents were used as received Compounds S11 S22 S33 and
S44 were prepared according to literature procedures 1H NMR spectra were recorded on high-field
spectrometers (1H frequency 50013 or 60013 MHz) equipped with broadband inverse gradient
probeheads Spectra were referenced to the residual solvent signals (chloroform-d 724 ppm) 13C
NMR spectra were recorded with 1H broadband decoupling and referenced to solvent signals
(13CDCl3 770 ppm) High resolution mass spectra were recorded using APCI or ESI ionization in the
positive mode
Computational methods Density functional theory (DFT) calculations were performed using
Gaussian 095 DFT geometry optimizations were carried out in unconstrained C1 symmetry using
molecular mechanics or semiempirical models as starting geometries X-ray geometries were used as
initial models for 3-Et and 4-Et DFT geometries were refined to meet standard convergence criteria
and the existence of a local minimum was verified by a normal mode frequency calculation DFT
calculations were performed using the hybrid functional B3LYP6ndash8 and the 6-31G(dp) basis set
Solvation effects were modeled using the IEFPCM formalism9 with standard solvent
parameterizations chloroform (1H and 13C NMR for 1ndash4-Et) dichloromethane (TD-DFT for 1ndash4-Et)
and NN-dimethylformamide (thermochemistry of the Yamamoto coupling) 1H and 13C shieldings
were calculated using the GIAO approach and referenced to the absolute TMS shieldings calculated
at the same level of theory (317454 ppm for 1H and 1920973 ppm for 13C) NICS scans were
performed with gas-phase calculated GIAO shieldings Electronic transitions were calculated by
means of time-dependent DFT (TD-DFT) All TD-DFT calculations were performed at the CAM-
B3LYP6-311+G(dp)6-31G(dp) level of theory10 using dichloromethane solvation
X-ray crystallography X-ray quality crystals were grown by slow diffusion of methanol into a toluene
solution of 3 same method was used to get crystals of 4 Diffraction measurements were performed
on a к-geometry Ruby PX diffractometer (ω scans) with graphite-monochromatized Mo Kα radiation
The data for 3 and 4 were collected at 100 K and 80 K respectively corrected for Lorenz and
polarization effects Data collection cell refinement data reduction and analysis were carried out
with the Xcalibur PX software CRYSALIS CCD and CRYSALIS RED respectively (Oxford Diffraction Ltd
Abignon England 2009) An analytical absorption correction was applied for the data of 3 and 4 with
use of CRYSALIS RED Both structures were solved by direct methods with the SHELXS-97 program
and refined using SHELXL-9711 with anisotropic thermal parameters for non-H atoms In the final
refinement cycles all H atoms were treated as riding atoms in geometrically optimized positions

Photoluminescence Photoluminescence excitation (PLE) spectra as well as decay kinetics (DEC) were
taken with the FSL980-sm Fluorescence Spectrometer from Edinburgh Instruments Ltd A 450 W
Xenon arc lamp (PL and PLE) and a Super Continuum Fianium laser were used as excitation sources
Emission spectra were corrected for the recording system efficiency and excitation spectra were
corrected for the incident light intensity The quantum yield measurements were performed by using
an Edinburgh Instruments integrating sphere equipped with a small elliptical mirror and a baffle plate
for beam steering and shielding against directly detected light For the measurement the integrating

To a 250 mL three-necked round-bottomed flask equipped with a reflux condenser septum and
syringe pump adapter were placed zinc powder (2250 mg 344 mmol) and copper(I) iodide (210 mg
11 mmol) The apparatus was filled with nitrogen and oxygen-free tetrahydrofuran (130 mL) was
introduced through a syringe Titanium tetrachloride (189 mL 172 mmol) was added dropwise the
septum was replaced with a glass stopper and the reaction mixture was heated and stirred under
reflux for 3 hours Subsequently a solution of compound S8 (100 mg 023 mmol) in oxygen-free
tetrahydrofuran (50 mL) was added to the reaction mixture using a syringe pump in 3 hours and the
mixture was stirred under reflux for another 12 hours After that time it was cooled down to room
temperature Aqueous ammonia (5 150 mL) was added and the mixture was stirred for 1 hour
Extraction with dichloromethane followed by drying the combined organic layers over anhydrous
sodium sulphate and removing the solvents on a rotary evaporator gave a yellow-green solid It was
purified using column chromatography (silicagel dichloromethanehexane = 110) yielding pale
green crystals (16 mg 173 ) 1H NMR (500 MHz chloroform-d 300 K) δ 763 (s 6H) δ 688 (s 6H)

fluorenephanetetraene (4-Et) In a 100 mL round-bottomed flask compound S8 (79 mg 018 mmol)
and compound S11 (200 mg 019 mmol) were dissolved in freshly distilled oxygen free
dichloromethane (80 mL) Aqueous sodium hydroxide (50 620 microL) was added dropwise to the
solution using a syringe During the addition the mixture was kept under a nitrogen atmosphere and
protected from light After the addition the solution was stirred for 1 hour After that time the
mixture was diluted with water and extracted with dichloromethane Combined extracts were dried
over anhydrous sodium sulphate filtered and the solvent was removed on a rotary evaporator

[4]chrysaorene (2-Et) In a 25 mL Schlenk flask equipped with a magnetic stirring bar compound 4-Et
(15 mg 93 micromol) was placed and the vessel was capped with a septum The atmosphere within the
flask was then changed a few times to nitrogen after which bis(15-cyclooctadiene)nickel(0) (31 mg
1110 micromol) and 22rsquo-bibyridyl (17 mg 1110 micromol) were added in a glove-box Dry NN-
dimethylformamide (5 mL) was then added to the vessel in a constant flow of nitrogen and the
mixture was sealed with a glass stopper After subsequent changing of the atmosphere to nitrogen
one more time the reaction mixture was heated to 85 degrees and stirred for 18 hours It was then
cooled down to room temperature diluted with water and extracted with dichloromethane The
combined organic extracts were dried over anhydrous sodium sulphate filtered and the solvents
were removed on a rotary evaporator The crude mixture was filtered through a short silica plug to
remove the solid impurities Subsequent purification by column chromatography (silicagel
dichloromethanehexane = 16) gave the product in a form of pale yellow solid (4 mg 441 ) 1H
