  Phthalocyanines with peripheral azo chromophores

  摘要：

  Interaction of 4-halogenated phthalonitrile with arylazophenols provided 4-R-azophenoxyphthalonitriles that have been further transformed into tetra-4-(4'-arylazophenoxy)phthalocyanines and their metal complexes. Physicochemical properties of the prepared compounds were studied.

  Synthesis of Liquid Crystals with Lateral Methyl Group and Study of Their Mesomorphic Properties

  摘要：

  Two new homologous series consisting of central azo and ester linkage and methyl groups at the central as well as terminal benzene rings are synthesized and their mesomorphic properties are studied. Between these two series; Series I has lateral methyl group on terminal benzene ring where as series II has lateral methyl groups at central as well as terminal benzene cores. All the homologues of series I and II are mesogenic in nature; series I exhibits nematic phase from C1 to C14 members whereas C16 member shows smectic C mesophase along with nematic mesophase on the other hand all the members of series II are nematogenic in nature. The nematic phase of the series I and II shows marble/schlieren texture and the smectic phase shows schlieren texture of smectic C variety. The mesomorphic properties of both the series are compared with each other and also with other structurally related series to evaluate the effect of lateral methyl group at central as well as terminal benzene core on mesomorphism.
