▎ 摘　　要

The synthesis and characterization, using NMR (H-1 and C-13), infrared spectroscopy, and X-ray crystallography, of the ethene and carbon monoxide copper(I) complexes of hydridotris(3,5-diphenylpyrazol-1-yl) borate ([Tp(Ph2)](-)) and the two new ligands hydridotris(3,5-bis(1-naphthyl) pyrazol-1-yl) borate ([Tp(1Nt) 2]-) and hydridotris(3,5-bis-(2-naphthyl) pyrazol-1-yl) borate ([Tp((2Nt)2)]-) are described. X-ray crystal structures are presented of [Cu(Tp(Ph2))(C2H4)] and [Cu(Tp((2Nt)2))(C2H4)]. The compound [Cu(Tp(Ph2))(C2H4)] features interactions between the protons of the ethene ligand and the pi-electron clouds of the phenyl substituents that make up the binding pocket surrounding the copper(I) center. These dipolar interactions result in strongly upfield shifted signals of the ethene protons in H-1-NMR. [Cu(Tp((1Nt)2))(CO)] and [Cu(Tp((2Nt)2)) (CO)] were examined using infrared spectroscopy and were found to have CO stretching vibrations at 2076 and 2080 cm(-1) respectively. The copper(I) carbonyl complexes form self-assembled monolayers when drop cast onto HOPG and thin multilayers of a few nanometers thickness when dip coated onto graphene. General macroscopic trends such as the different tendencies to crystallize observed in the complexes of the two naphthyl-substituted ligands appear to extend well to the nanoscale where a well-organized monolayer could be observed of [Cu(Tp((2Nt)2))(CO)].-
