Triphenylamine functionalized salicylaldimine difluoroboron complexes bearing different substituents have been synthesized. The photophysical results showed that these complexes exhibited intramolecular charge transfer (ICT) emission and solvatochromism.

A series of novel Zn(II) Schiff base complexes with diphenylamino and carbazole groups that exhibited aggregation-induced emission enhancement were designed and synthesized. The properties of four complexes were investigated by UV-Vis absorption and fluorescence emission spectroscopy, cyclic voltammetry and density functional theory calculations. The fluorescence intensities of the four dyes are weak in tetrahydrofuran, but become strong in a mixture of water/tetrahydrofuran (v/v = 9/1). This work constitutes the first observation of this phenomenon for Zn(II) Schiff base complexes. A simple model complex, without the possibility of intramolecular rotational motion, was prepared in order to determine the mechanism of the AIEE. The present aggregation-induced emission enhancement was attributed to restricted intramolecular rotational motions in the solid by carefully analyzing the difference in molecular structure and photophysical properties amongst the new complexes.
