主　　题：Colorimetric receptor Urea Viologen Dicarboxylate 

摘      要：Compound 1 bearing urea and viologen groups has been designed and *** could be used as a colorimetric receptor for dicarboxylate anions due to the significant color changes of the solution upon the addition of *** importantly,the color changes were related to the chain lengths of the dicarboxylates ***-vis,＇H NMR and HRMS studies demonstrated that receptor 1 utilized hydrogen bonds and electrostatic interactions to form 1：1 stoichiometry complexes with these *** addition,the generation of cation radical 1＇ during the complexation process was also detected by EPR.
