A dual-mode orthogonally tunable fluorescent system covering the whole white light region

Abstract

Using a supramolecular strategy to adjust the emission of organic small molecules has attracted considerable attention recently. Here, we design a fluorescent host–guest system consisting of two fluorophore components, perylene bis(diimide) (PDI) and coumarin, which could be adjusted in an orthogonal mode. This fluorescent host–guest system can be switched in multiple emissions, including white-light emission.
