We synthesized new series of octakis(4-(N-(4-alkoxyphenyl)iminomethyl)phenoxy)cyclotetra phosphazene [PN(OC_6H_4CH=NC_6H_4OC_nH_<2n+1>)_2]_4 (OCTP-n), where n is a carbon number of end alkoxy groups. Their liquid crystalline phase transition and mesogenicity were studied by DSC measurements and polarizing microscope observations. A series of OCTP showed an enantiotropic smectic A phase for n ≦ 7.
