Unique X-ray sheet structure of 1,8-bis(imidazolium) anthracene and its application as a fluorescent probe for DNA and DNase

Abstract

A new imidazolium anthracene derivative 1 was synthesized, and its unique X-ray crystal structure was examined. In aqueous solutions, probe 1 exhibited a selective fluorescent quenching effect only with DNA among various anions including the nucleotides investigated. This probe was further applied to monitor the activity of DNase. © 2011 American Chemical Society.
