Bistable [2]rotaxane encoding an orthogonally tunable fluorescent molecular system including white-light emission

Abstract

Orthogonally tunable multicolor fluorescence including white-light emission was achieved using a dual-component molecular system. Under external acid/base stimuli, we were able to change the fluorescence of a mixture of two fluorescent molecular switches in an orthogonal and reversible manner, hence generate emission of multiple colors from blue to yellow, including white light (CIE (0.29, 0.34)).
