| Abstract: | Due to the fundamental roles that anions play in a wide range of chemical and biological processes,numerous efforts have been devoted to the design of receptors capable of selectively binding and sensing anions.Herein,carbazole derivative(1) bearing two model amides was synthesized by coupling 1,8-diamino-3,6-dichlorocarbazole with pyrrole-2-carbonylchloride in the presence of triethylamine.The structure of compound 1 was characterized by X-ray crystallography.The anions recognition of the compound 1 was st... |
