INVESTIGATION OF ULTRASONIC VELOCITY AND RELATED PARAMETERS IN LIQUID CRYSTALLINE MIXTURES.

Investigations of ultrasonic velocity, specific volume and related parameters were carried out in a mixture of p-n-butoxybenzylidene-p-chloroaniline (BBCA) and p-anisal-p-toluidine (pApT) at eight different concentrations. BBCA exhibits polymorphism with

Synthesis and antimicrobial activity of 1-(p-substituted)phenyl-3-(p-alkoxy)phenyl-4-phenyl-azetidin-2-ones

A series of 1-(p-substituted)phenyl)-3-(p-alkoxy)phenyl-4-phenyl-azetidin-2-ones 1a-20a, was synthesized and characterized. Their antimicrobial activity, against Gram+ and Gram - bacteria and Fungi, was tested. The compounds 8a, 13a, 14a, 18a and 6a, 9a,

A Mixture-Induced Nematic Phase

We report on an unusual variant in liquid crystal polymorphism where a nematic phase is created from a binary mixture of two compounds, neither one of which in its pure state exhibits the nematic phase.One of the compounds in its pure form exhibits only a smectic A phase which is stabilized by an extended alkyl chain.The other compound in its pure form exhibits a smectic A and a smectic B phase which are stabilized by a terminally substituted halogen.When mixed, a wide-temperature-range nematic is created.This induced nematic is studied by x-rays, differential scanning calorimetry, and by varying the terminal halogen.

Liquid Crystalline Properties of N-(4-Alkoxybenzylidene)-4-halogenoanilines

N-(4-alkoxybenzylidene)-4-halogenoanilines have been synthesized, and phase transitions determined using a differential scanning calorimeter and a polarizing microscope.Smectic and nematic phases have been observed for fluoro and chloro derivatives whereas bromo and iodo derivatives exhibit only a smectic phase.
