  New Liquid Crystalline Compounds Involving Ester-Chalcone Linkages Having 1,3,5-Trisubstituted Pyrazole as a Terminal Group

  摘要：

  Mesogens with chalcone central linkage are rare. It has been observed that -CO-CH=CH- linkage is less conducive to mesomorphism compared to -CH=N-(azomethine), -COO- (ester), -N=-(azo) linkages due to the non linearity and angle strain arising from the keto group. But when -CO-CH=CH- linkage is present with other central linkages it becomes condusive to mesomorphism. In the present investigation two homologous series were synthesized having chalcone as a one of the central linkage. The homologous series have been derived from 1,3,5-trisubstituted pyrazole, p-hydroxy acetophenone, and alkoxy acid. Viz. 4(4 '-n-alkoxybenzoloxy) phenyl-propane-3-one(1-phenyl-3-methyl-2-pyrazoline-5-one) [series-I] and 4(4 '-n-alkoxybenzoloxy) phenyl-propane-3-one(1-phenyl(4 ''-methyl)-3-methyl-2-pyrazoline-5-one) [series-II]. The compounds of the both series have been characterized by elemental analyses, FT-IR, H-1-NMR, and Mass spectrometry methods. Their liquid crystalline properties have been investigated by optical polarizing microscopy and DSC studies. All the derivatives are mesomorphic in nature. C-1 to C-5 of both the series exhibit only nematic phase. C-6 to C-8 in series-I and C-7 & C-8 in series-II exhibit smectic as well as nematic phase. Whereas C-10-C-16 in series-I and C-8-C-16 in series-II showing only smectic phase.

  The synthesis and the mesomorphic properties of various series of isometric mesogenic compounds are described. It is confirmed that isometric mesogenic molecules may be nematogenic and/or smectogenic according to the position of the polar rigid core.
