Roughly focus on two major kinds of ligand (H[PNP] and [PO3]H3) my work since more than one year. One of them R[PNP]H (R=iPr, Ph), We take these two ligands reacting with a series of Cu¡BAg,by good luck ,we get seven metal complexes. Among them that quite make us pleasantly surprised is Ph [PNP ] Cu dimer have quite good luminescence characteristics under the general visible light condition of the room temperature, we are sure that this characteristic can be used in many aspects such as electrochemical divices, as sensors and biological imaging agents, and in solar conversion schemes. Nitrogen fixation catalyzed by nitrogenases is an important process in biology. Recently, we are interested in this topic, and devoted in creating new metal complexes could play as an nitrogenases. For this reson, we use a bulky ligand [PO3]H3 reacting with lots of different meals including Li¡BCo¡BSn and group IV. We report herein the synthesis, characterization of them.
