The invention provides a stilbene nitrile derivative shown in formula (I), and its preparation method is: p-bromobenzaldehyde shown in formula (II) and 4-boric acid triphenylamine shown in formula (III) are generated by Suzuki reaction Triphenylamine intermediates shown in formula (IV); triphenylamine intermediates shown in formula (IV) and 4-methoxybenzonitrile shown in formula (V) generate described distyrylonitrile derivatives through Knoevenagel condensation reaction The force-stimuli-responsive fluorescent switch performance of the stilbene nitrile derivatives of the present invention has the characteristics of high contrast, self-recovery, and good cycle performance, and the synthesis method is simple. It can be used as a reversible force-stimulated fluorescent switch material for fluorescent switches, Sensors, storage and display and other fields. |
