合成了一个新颖的金属铜和1,2-双(2′-甲基-5′-(4″-吡啶基)-3′-噻吩)全氟代环戊烯(BM-4-PTP)配合物,并用红外、核磁共振、元素分析进行了表征。研究了配合物在晶体相的光致变色性质和磁性性质。在光激发下,配合物[Cu(BM-4-PTP)2(CF3COO)2](THF)2(H2O)2(1)在晶体相显示出可逆的光异构反应。有趣的是,伴随着光致变色反应,配合物1的开环体(1o)和闭环体(1c)在晶体相还显示出磁性差异,1o和1c的磁化率可逆地发生变化,说明由于开环异构体和闭环异构体的π共轭结构不同,通过配体BM-4-PTP桥联的铜离子之间的相互作用可以被光引发。
A novel copper (II) complex with 1,2-bis (2’-methyl-5’- (4 "-pyridyl) -3’- thiophene) perfluorocyclopentene (BM-4-PTP) (Cu (BM-4-PTP) 2 (CF3COO) 2) complexes were synthesized and characterized by IR, 1H NMR and elemental analysis.The photochromism and magnetic properties of the complexes in the crystalline phase were investigated.Under the photoexcitation, 2] (THF) 2 (H2O) 2 (1) shows a reversible photoisomerization reaction in the crystal phase Interestingly, with the photochromic reaction, the ring-opening body 1o of the complex 1 and the ring- 1c) shows a magnetic difference in the crystal phase. The magnetic susceptibility of 1o and 1c changes reversibly, indicating that due to the difference of the π-conjugated structure between the ring-opened isomer and the ring-closed isomer, the ligand BM-4-PTP bridge The interaction between copper ions can be photoinitiated.
