| titleOfInvention | Phenyl boron fluorine complex and preparation method and application thereof |
| abstract | The invention discloses a phenyl boron fluorine complex capable of restoring color change at room temperature and a preparation method thereof, belonging to the field of organic synthesis. The preparation method comprises the following steps: (1) reacting halogen-containing triphenylethylene with acyl phenylboronic acid to prepare tetraphenyl vinyl monoketone; (2) synthesizing tetraphenyl vinyl beta-diketone from tetraphenyl ethylene monoketone and ethyl acetate; (3) boron trifluoride diethyl etherate is complexed with the tetraphenylvinyl beta-diketone to obtain a phenylboron-fluorine complex. The phenyl boron fluorine complex is sensitive to heat, can spontaneously recover to the original color at room temperature after being subjected to color change through friction, can be repeatedly used, has a huge application prospect in the fields of information confidentiality, sensors and the like, and simultaneously, the ethyl acetate is used as a solvent and a reactant, so that the use of the solvent is reduced in the reaction process, and the influence on the environment is reduced. |
