摘要：

A new triphenylamine-based receptor 1 has been designed and synthesized for the recognition of aliphatic dicarboxylates of various chain lengths. This receptor has been designed to utilize an amide-urea conjugate for binding dicarboxylates. The receptor 1 is found to bind the dicarboxylates with moderate binding strength under a semi rigid, propeller shaped, fluorescent triphenylamine spacer. The binding behavior was studied in CH3CN using H-1 NMR, fluorescence and UV-vis spectroscopic methods. The conformational behavior of 1 and its complexation modes have been investigated using classical and quantum mechanical theoretical methods. The receptor is found to be selective for long chain suberate. (C) 2009 Elsevier Ltd. All rights reserved.
