    final symmetric compounds. In the case of the PEB series, a slight different route was employed; and initially the bis(benzoyl)hydrazine cores were prepared and then, the cores were extended by attaching p-alkoxyphenylacetylene to both terminals. To examine the role of hydrogen bonding interaction acting with the molecular core in the phase behavior, the bis(phenylbenzylidene)hydrazine core was selected. Starting from the carboxylate ester having long alkyl tails, the phenyl benzyl alcohol was prepared and then, changed to the corresponding aldehyde, and finally, two aldehydes were coupled with a hydrazine to obtain the final symmetric compound having n = 22 tails PBID-22 (9a). For the unsymmetric compounds, the acid chlorides and acid hydrazides were initially prepared to incorporate different aromatic cores with different sizes in them, and they were combined. 1.2. Characterization

    All solvents and reagents were obtained from commercial sources and used without further purification unless noted. The purity and characterization of all intermediary compounds and the final compounds were checked by a combination of thin-layer chromatography (TLC: on silica gel coated glass plates (Merck) with fluorescent indicator), NMR spectroscopy, and elemental analysis. 1H NMR (400 or 600 MHz) spectra were recorded on a JEOL ECA600 or a JEOL ECS400 spectrometer, and CDCl3, pyridine-d5, tolune-d8, THD-d8, DMSO-d6, and DMF-d7 were as solvents and tetramethysilane (TMS) was used as internal standard ( = 0.00). Chemical shifts are reported as in parts per million downfield from TMS. Elemental analyses were carried out at Laboratory of Organic Elemental Microanalysis, Kyoto University, and performed using a J-Science Labo micro corder JM10 at Division Instrumental Analysis, Life Science Research Center, Gifu University. Phase transitions were determined by using a Seiko Denshi DSC-200 interfaced to a TA data station (SSC 5000 system) and a SII Nanotechnologies DSC7020. The measurements were performed under a dry N2 flow of c. 40 mL min-1 and the scanning rate was 5 K min-1. The texture of each mesophase was observed usually under crossed polarizers using polarizing optical microscopes (POM; a Nikon Optiphot-pol XTP-11 and an Olympus BX53P) equipped with a Mettler FP82HT hotstage and a Mettler FP90 controller. The scanning rate was 5 or 1 K min-1. For the observation of a conglomerate of chiral domains, the sample was heated to an objective temperature from room temperature at 10 K min-1 and the sample thickness was 44 m using a PET film spacer. The brightness of the two kinds of domains were inverted when the position of the analyzer was changed from +10 to 10 out of the precise 90 position with respect to

    the polarizer. X-ray diffraction (XRD) patterns at elevated temperatures were obtained for powder samples using a Rigaku NANO-Viewer IP system. CuK radiation was used at 45 kV and 60 mA. The scattered X-rays were recorded on a two-dimensional imaging plate (IP). The intensities were radially integrated and averaged, and redistributed when converting the pixel number into the corresponding scattering vector q (q = (4/)sin, with being the X-rays wavelength (= 0.15418 nm) and 2 the scattering angle) to produce a circularly averaged pattern. In some cases, to confirm the phase behaviors in detail, time-resolved XRD measurements were performed using synchrotron radiation at the Photon Factory (PF) in the High-Energy Accelerator Research Organization (KEK). The sizes of the molecular cores were evaluated on the basis of M06/6-31G* density functional theory. The detailed computational procedures are given in section 6.

    FT-IR spectra were recorded with a Jasco FT-IR-460 Plus / IRT-30 spectrometer equipped with a Mettler FP82HT hotstage and a Mettler FP90 controller at Division Instrumental Analysis, Life Science Research Center, Gifu University. The samples were sandwiched between two KBr plates (551 mm3) and placed on the hotstage. The measurements were performed on the transmittance mode with 100 scans at 4 cm-1 optical resolution. The sample room was purged with N2 gas. 2.
