When electron-deficient nitro-compounds interact with electron-rich fluorescent compounds of alkynyl substituted triphenylamines,it will cause the changes of the conjugate degree and the charge distribution of the fluorescent compounds,resulting in the change of fluorescence.Alkynyl substituted triphenylamines were designed and synthesized via sonogashira coupling reaction using alkynes and halogenated triphenylamines as raw materials.The effects of molecular structure,solvent polarity,and addition of nitro...
