A fluorescent cross-linked supramolecular network formed by orthogonal metal-coordination and host–guest interactions for multiple ratiometric sensing†
Abstract
A cross-linked supramolecular network was prepared by the orthogonal self-assembly of metal-coordination and host–guest interactions. Due to the incorporation of two fluorophores, coumarin and tetraphenylethene, into the network as well as the abundant stimuli-responsiveness of the two non-covalent interactions, it can be used for the ratiometric sensing of pH, cyclen and Cl−.
