Abstract
Herein, the turn-off fluorescence sensor of 2-((4′-(7,8,13,14-tetrahydrodibenzo[<italic>a</italic>,<italic>i</italic>]phenanthridin-5-yl)-[1,1′-biphenyl]-4-yl)methylene)malanonitrile (<bold>7</bold>) was developed for the recognition of CN<sup>−</sup>ions and studied using different spectroscopic techniques.
