Facile Synthesis of a Selective Biomolecule Chemosensor and Fabrication of Its Highly Fluorescent Graphene Complex

摘要: A novel hydrophilic imidazolium fluorescent chemosensor has been utilized to prepare water-soluble graphene complex via a facile ion-exchange strategy, which gives very high quantum yield (0.87). The highly displays close resemblance the chemosensor, as chemisorbed hinders electron transfer between naphthalene moiety and graphene. If is simply physisorbed on by physical mixing, it does not show because π–π stacking leads fluorescence quenching. selectively detects RNA turn-on at physiological pH in aqueous solution. well would find potential applications photoresponsive materials biomedical probes.
