Complexation and Fluorescence Enhancement of Bay-site Carboxyl Modified Perylene Dimide with Calcium Ion
摘要
Abstract
Bay-site carboxyl functionalized perylene diimide derivative 1,7-COOH-PDI-C12(PDI-COOH)was syn-thesized and distinct enhanced fluorescence was observed through combining with calcium ion(Ca2+)in THF/H2O so-lution.The assembly and fluorescence behavior of PDI-COOH/Ca2+were studied in detail by changing hydration state with different concentrations.Based on the differences in assembly morphology and stoichiometric ratios of PDI-COOH/Ca2+,we proposed the fluorescence emission mechanism of PDI-COOH/Ca2+in THF/H2O and THF,respec-tively.This work reveals a novel strategy of aggregated state fluorescence enhancement and reminds us of the impor-tant role of water in molecular fluorescence emission and assembly.关键词
