Salen, salan and salalen zinc(ii) complexes in the interaction with HS−: time-resolved fluorescence applications

Abstract

In the current work we investigate the route of interaction of a newly synthesized family of zinc complexes with HS⁻ by a plethora of different spectroscopic techniques. A computational analysis on the time dependent density functional theory (TD-DFT) level explored the overall fluorescence properties of the title complexes and their different fluorescence responses to HS⁻. Time-resolved fluorescence experiments were also performed and highlight the great potential of the current systems to be implemented as HS⁻ fluorescent sensors.
