Size recognition and optical unloading of polyaromatic compounds based on a coordination box containing face-to-face olefin bonds†‡
Abstract
Pyrene-R with strong fluorescence can be quenched after being encapsulated into the organometallic box of complex 1. The fluorescence can be resumed though a [2 + 2] cyclo-addition reaction in the molecular pocket of complex 1 to release pyrene-R.
