Highly specific fluorescent probes toward acetic acid via structural transformation of zinc complexes

Abstract

Highly sensitive and specific acetic acid probe is desirable to distinguished it from other fatty acids. Herein, we designed and synthesized two zinc complexes H2tBuCarPyZn2Br4(AcO)2•AcOH (1) and H2tBuCarPyZn2Br4(AcO)2 (2). Both...

Pyridine-Triggered Fluorescent Switching in Coordination-Induced Allosteric Crystal Transformation

“…It is worth mentioning that zinc and nickel have advantages over Fe II due to their incomparable stability in the oxidation state under aerobic conditions and the potential for colorimetric/fluorescent probes. − For example, a Ni II quinonoid complex demonstrated selective spin-state switching in response to methanol vapor, as discovered by Kato and colleagues . Chen and co-workers, inspired by reversible vapochromic during the uptake and release of acetic acid, developed acetic acid probe using Zn II complex . Furthermore, compared to crystal structure transformation with indirect intermolecular contacts, the number of phase transitions in crystal structures caused by direct coordination of gas-phase molecules is comparatively rare. ,,− …”
