AbstractNovel disubstituted propiolates bearing chromophoric terphenylene mesogenic groups, namely, 4'-cyano-4-terphenylyl-2-octynate M(CN) and 4'-methoxyl-4-terphenylyl-2-octynate M(OCH(3)) are synthesized, where the terphenyl groups are connected to the C=C through ester linkage directly. Using transition-metal catalysts such as the classical MoCl(5)- and WCl(6)-based metathesis catalysts, the polymerization of the M(CN) and M(OCH(3)) are carried out in a series of different solution, however, did not obtain any products. It suggests that the WCl(6)- and MoCl(5)-based catalysts are poisoned by the polar groups, on the other hand, the bulk terphenyl groups and the long alkyl chain around the C=C bond might inhibit the reaction. M(CN) displays monotropic nematicity, whereas M(OCH(3)) exhibits enantiotropic nematicity and smecticity (SmA(d)) with a bilayer arrangement when cooled and heated. Ultraviolet spectroscopy and photoluminescence measurements also show that the terphenyl groups endow disubstituted propiolates with strong UV light absorption and high photoluminescence.
