| Synthesis and Photochromism of a Novel Photomagnetic Copper(Ⅱ) Complex with Dithienylethene Ligand |

| 摘要: 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。 |

| Abstract: One novel copper complex with 1,2-bis(2′-methyl-5′-(4″-pyridyl)-3′-thienyl) perfluorocyclopentene (BM-4-PTP) was synthesized and characterized by IR, NMR and elemental analysis. The photochtomic and magnetic properties of the copper complex were examined in crystalline state. Upon photoirradiation, [Cu(BM-4-PTP)2(CF3COO)2](THF)2(H2O)2 (1) displayed reversible photoisomerization in crystalline phase. Interestingly, complex 1 also showed reversible photomagnetism between open-form (1o) and closed-form (1c) accompanying the photochromic reaction in crystalline phase. The magnetic susceptibilities of 1o and 1c reversibly changed indicated the copper-copper interaction through the bridging BM-4-TTP is switched upon photoexcitation due to the different π-conjugated bond structures between the open and closed isomers. |
