| 摘 要： | Two new metal-organic frameworks, {Cd2CI（HL）（H20）2＂0.5H20]}n （1） and {Cd2L（H20）2]＇H20}n （2）, have been hydrothermally synthesized with designed ligand H4L （HaL = 1,3,5-triazine-2-iminodiacetic acid-4,6-biglycine） under the same condition except for different pH values. Single-crystal X-ray determination shows that they are 3-D frameworks. Complex 1 crystallizes in monoclinic, space group P21/n. Complex 2 crystallizes in triclinic, space group Pi. The photoluminescence properties of those two complexes have been investigated in solid state. Complexes 2 exhibited remarkable blue luminescence emissions with high quantum yield of 40.3% On the other hand, complexes 1 featured weak quantum yields of 13.7%.
