  Mesomorphism dependence of a terminal or lateral alkoxy group

  摘要：

  A novel homologous series of thermotropic mesomorphs has been synthesized and studied with a view to understanding and establishing the effect of molecular structure on mesomorphic properties with reference to rigidity and flexibility of the homologues series: RO-C6H4-CHCH-CO-C6H4-OC18H37(n). The novel homologous series comprises 13 novel homologues (C-1 to C-18), from which 11 homologues are enantiotropically mesogenic (C-3 to C-18). Smectogenic mesophase commences from C-7 homologue, and nematogenic mesophase is exhibited by C-3 to C-18 homologues in enantiotropic manner. Thus, C-7 to C-18 homologues are enantiotropically smectogenic plus nematogenic. Textures of smectic phase are of the type A or C, and that of nematic phase are threaded or Schlieren as confirmed through an optical polarizing microscope equipped with a heating stage. Transition curve of a phase diagram behaved in a normal manner except N-I transition curve, which shows minor deviating trend (C-12 to C-18) from expected normal behavior. An odd-even effect is exhibited by N-I and Sm-N transition curves. Analytical, spectral, and thermal data confirm the molecular structures of novel homologues. Thermal stabilities for smectic and nematic are 52.7 degrees C and 66.6 degrees C, respectively, whose total mesophase lengths range from 12.0 degrees C to 28.0 degrees C. Thus, novel series of chalcones is a low melting series whose mesogenic transition temperatures vary between 38.0 and 86.0 degrees C.
