Paragraph 0013; 0048-0049, (2021/10/05)
The invention aims to provide a method for synthesizing a carbazole derivative. The method is characterized in that palladium chloride is used as a catalyst, 2, 2' - dibromobiphenyl is used as an electrophilic reagent, primary amine is taken as a nucleophile, and the carbazole derivative is directly cross-coupled under the conditions of toluene as a solvent and an air atmosphere. The method has the advantages of high yield, high selectivity, simplicity and convenience in operation and the like.

Six carbazole-based dyes were synthesized by fluorescence turn on amino-ene click reactions. Two high quality single-crystals of new dyes were prepared, and their X-ray diffraction structure analyses reveal the formation of antiparallel stacking superstructures driven by self-complementary dipole-dipole and π-stacking interactions between carbazole donors and acceptors. The optical behaviors and donor-acceptor interactions of these dyes were investigated by ultraviolet–visible absorption, fluorescence emission spectroscopy, and electrochemical cyclic voltammetry. Blue fluorescence appears and increases as dye-based supramolecular polymer grows, as revealed by dynamic light scattering, fluorescence, 1H NMR and 2D NMR spectroscopy.

In this work, we introduced a blue fluorescent material with twisted A-π-D-π-A configuration, namely CzPA-F-PD. This compound exhibits remarkable dual fluorescence properties triggered by trifluoroacetic acid (TFA), resulting in blue and red emission peak
