摘要

Liquid crystalline and light emitting properties of two new disubstituted polyacetylenes bearing biphenyl pendants (-{(R)CC[(CH₂)₄OCO-Biph-OC₇H₁₅]} _n-, RCH₃ (1), C₆H₅ (2), Biph=4,4^′-biphenylyl) were investigated. Whereas 1 formed enantiotropic nematic phase, 2 was non-mesomorphic. Upon photoexcitation, the THF solutions of 1 and 2 emitted strong UV and blue light of 369 and 460 nm, respectively, whose quantum efficiencies were higher than that of poly(1-phenyl-1-octyne), a highly luminescent disubstituted polyacetylene.
