| titleOfInvention | Seven-element fluoroboric fluorescent dye and synthetic method thereof |
| abstract | The invention discloses a novel hepta-boron fluoride fluorescent dye containing an electron donor/electron acceptor and a synthesis method thereof, wherein the structure of the compound is as follows: wherein, the substituent R is electron-donating groups such as alkoxy, amino, hydroxyl and the like, and electron-withdrawing groups such as acyl, aldehyde group, carboxyl, acylamino, sulfonic group, nitrile group, nitro, haloform group, quaternary ammonium group and the like. 2, 3, 3-trimethylindole derivatives and 2-formylpyrrole are taken as raw materials and are subjected to Knoevenagel condensation reaction under the action of an organic catalyst to finally generate the electron-donating/electron-withdrawing heptatomic fluoroboron fluorescent dye. The seven-element boron fluoride fluorescent dye containing the electron donor/electron acceptor has the advantages of simple synthesis method, easily controlled reaction conditions and universal applicability. The material can effectively regulate and control the pi conjugation, the energy band gap and the photoelectric property by selecting a proper fluorophore, an electron donor and an electron acceptor. |
