Miscibility Studies of some Liquid Crystalline Substances with Hexadecyloxyazoxybenzene

Liquid Crystal Group, Department of Chemistry, University of Jammu, Jammu-150 004 Manuscript received 9 July 1991, accepted 20 September 1991 The diagrams of state have been studied for some binary liquid crystal mixtures. Each of the systems studied contains bexadecyloxyazoxybenzene (HOAB) as one component while the other one is hexyloxybenzylideneaminoazobenzene (HBAAB), heptyloxyhenzylidene heptylaniline (HBHA) and metboxybenzylidene- aminoethylcinnamate (MBAEC). All the phases in these systems remain confined to their respective sides. On the basis of miscibility studies with HOAB smectic B phase in HBAAB, HBHA and MBAEC is established
