Abstract
A series of 2-(4-n-alkoxybiphenl)-5-(4-methylphenyl)pyridne (CH3C6H4C5H5NC6H4C6H4OCnH2n+1, n=1-10) (ABPMPP) was synthesized and their mesogenicity was studied using polarizing microscope observations and DSC measurements. The polymorphism of smectic phases was observed in the ABPMPP homologues of n≧3, while a nematic phase was found in all the member of ABPMPP.
