Dissipative control of the fluorescence of a 1,3-dipyrenyl calix[4]arene in the cone conformation

Org Biomol Chem. 2021 Dec 22;20(1):132-138. doi: 10.1039/d1ob02096j.

Abstract

The temporal control (ON/OFF/ON) of the fluorescence of a dichloromethane/acetonitrile 1 : 1 solution of calixarene 3 decorated with two pyrenyl moieties at the upper rim is attained by the addition of CCl3CO2H used as a convenient chemical fuel.
