摘　　要：The lantern-shaped cage Pd_(2)L_(4)and tweezer-like PdL_(2)can be synthesized from the trans-and cis-isomer of an azobenzene-containing ligand,respectively,which were characterized by^(1)H,^(13)C,^(1)H-^(1)H COSY,DOSY NMR spectroscopies,high-resolution ESI-MS and density function theory(DFT)calculations.The interconversion of Pd_(2)L_(4)and PdL_(2)can be achieved via the cis-trans isomerization of the azobenzene unit on the ligand upon alternative irradiation of light 365 nm or 420 nm.
