The present invention provides DM-based fluorophores F1-F5 with AIE effect and Cu 2+ The invention discloses a fluorescent probe FP1, a derivative based on dicyanomethylene-4H-pyran (DM) usually shows a fluorescence quenching effect, five fluorophores (F1-F5) with aggregation-induced emission (AIE) properties by functionalizing the fluorescent probe FP1, and a preparation method and application of a copper ion fluorescent probe (FP1) based on F1. In the invention, a terpyridine serving as a recognition group is coupled with F1 to generate a fluorescent probe FP 1. THF-H at a water content of 90% 2 In the mixed solution of O, the probe FP1 shows stronger fluorescence emission, and Cu is added 2+ In the case of aqueous solution of (A), terpyridine is complexed with the terpyridineAnd combined, resulting in fluorescence quenching. The probe is Cu in an aqueous solution 2+ The detection aspect of (2) has certain application value. |
