【摘要】 用固液相法合成了新型联邻甲苯胺双缩水杨醛和单缩水杨醛Schiff碱配体(L1和L2)。L1分别与金属离子[M=Cu(Ⅱ),Ni(Ⅱ),Co(Ⅱ)]配合,合成了三个新型的Schiff碱配合物ML1。L和ML1的结构经1HNMR,IR及元素分析表征。用UV-Vis研究了L和ML的热致变色性能,结果表明:L和ML均具有较好的热致变色性能。更多还原

【Abstract】 Novel o-tolidine bis-and single-salicylic aldehyde Schiff base ligand(L1,L2) were synthesized by solid and liquid-phase method.Three novel Schiff base metal complexes,CoL1,CuL1 and NiL1,were synthesized by complexing reaction of L1 with metal ion[Cu(Ⅱ),Ni(Ⅱ),Co(Ⅱ)],respectively.The structures were characterized by 1H NMR,FT-IR and elemental analysis.The thermochromic properties of L and ML1 were investigated by UV-Vis.The results showed that the L1 and ML1 exhibited good thermochromic properties.更多还原
