Liquid-Crystalline and Orientation Properties of Lanthanide Complexes with beta-Enaminoketone

摘要

A series of liquid-crystalline lanthanide complexes with 1-(4-dodecyloxyphenyl)-3-octadecyl-amino-2-propene-1-one(HL),which is substituted beta-enaminoketone,with the composition Ln(HL)_3(NO_3)_3(Ln = La,Nd,Gd,Tb,Dy,Ho,and Er)is synthesized.For the most part of the synthesized complexes,the magnetic susceptibility anisotropy(DELTA lambda_(min))is shown to be one to two orders higher than DELTA lambda of the"classical"organic liquid crystals.
