摘要

Mesomorphic and luminescent poly(propiolates) with different skeleton structures (-{(R)C=C[CO2(CH2)6OCO-Biph-OC7H 15]}n-; R = H (1), CH3 (2), C6H5 (3), Biph = biphenylyl} are synthesized. The backbone absorption in 2 and 3 are weak but upon photoexcitation, the polymers emit strong violet light of 369 nm, whose intensities are higher than that from poly(1-phenyl-1-octyne), a well-known highly fluorescent polyacetylene. The main chain of 3 absorbs strongly at 380 nm and the polymer is completely nonluminescent. All the polymers are thermally stable and form enantiotropic monolayer SmA phase, with 1 adopting well-ordered packing arrangements.
