摘要：
Poly(amidoamine)-based liquid crystalline dendrimers (LCDs) with mesogenes on the surface were successfully prepared by the reaction of poly(amidoamine) dendrimers with 4'-cyanobiphenyl hydrogen glutarate in the presence of a condensing agent, diphenyl(2,3-dihydro-2-thioxo-3-benzoxazolyl)phosphonate. The structures of LCDs were characterized by IR, H-1-NMR and MALDI-TOF mass spectroscopy and elemental analysis. These LCDs did not show a thermotropic liquid crystalline nature but exhibited a lyotropic liquid crystalline property in the 80 wt% DMF solutions of LCDs containing lithium bromide.
