摘要

Syntheses of new oligothiophenes which have cyano and hexyl groups at the ends of quarter-and ter-thiophenes are described. The observations of DSC and polarizing microscopy indicate the presence of liquid-crystalline (LC) phases over a wide temperature range. The energy gaps are discussed on the basis of the absorption and photoluminescence (PL) spectra and cyclic voltammetry. Thin films of oligothiophenes ...
