摘要：

Reaction of 5-(t-butyldiphenylsiloxy)propyloxyisophthalic with dodecanol and diphenylphosphoryl azide (DPPA) affords the diurethane via Curtius reaction. Removal of the silyl group affords an alcohol which undergoes similar reaction with,the isophthalic acid. Iteration of the process affords dendritic wedges through generation four, which can be attached to 1,3,5-benzenetricarboxylic acid in the same fashion. Materials are characterized by NMR and MALDI-TOF mass spectrometry. (C) 1998 Elsevier Science Ltd. All rights reserved.
