摘要
The reaction of 1.2-bis(2-pyridylethnyl)benzenes (L1-L5) with copper(I) ions proceeded smoothly to afford mononuclear copper(I) chelate complexes CL1-CL3 or dinuclear copper(I) molecular rectangular boxes. CL4 and CL5, in excellent yields, depending on the size of the substituent. If a ligand with a small substituent was used. the self-assembly of a mononuclear copper(I) chelate complex was achieved. If a ligand with a bulky substituent was used, the self-assembly of dinuclear copper(I) molecular rectangular boxes was achieved. The equilibrium between these two copper(I) complexes Was also observed in solution.
