Synthesis and Mesomorphic Properties of N-n-Alkyl-N--Piperazines

We have synthesized the N-n-alkyl-N'--piperazines and studied their physical properties using calorimetric, optical and X-ray methods.Depending on alkyl chain length there are one or two liquid crystal phases.For the lower homologs there is a nematic and a smectic phase with the smectic being identified as probably smectic A and in the higher homologs only the smectic is present.The smectic phase has an interdigitated bilayer and the transition heat of the nematic-smectic transition becomes very small with decreasing alkyl chain length.

Synthesis and Mesogenic Properties of N'-(4-Acylphenyl)-N-alkylpiperazines

One synthesis of N-alkyl-N'-(4-acylphenyl)piperazines and their physical properties have been studied using calorimetric, optical, and X-ray crystallography methods.The compounds exhibit only smectic phases, the higher-temperature phase being a probable s
