Abstract Microwave-assisted hydrothermal reaction of 2-fluoro-3,5,6-tri(1H-1,2,4-triazol-1-yl)-1,4-benzenedicarbonitrile (L1) with silver(I) nitrate yields a coordination polymer [Ag3(L2)2(NO3)] n (1), in which the L2 ligand (HL2 = 2-hydroxy-3,5,6-tri(1H-1,2,4-triazol-1-yl)terephthalonitrile) is obtained by in situ ligand transformation from the L1 precursor. HL2 monohydrate has also been isolated by the microwave-mediated hydrolysis of L1 and structurally characterized. Single-crystal X-ray diffraction reveals that HL2 monohydrate comprises a zwitterionic HL2 moiety, while complex 1 displays an infinite L2-bridged double-chain structure. Given that the HL2 molecule has a large conjugated π system, complex 1 exhibits strong blue luminescence in the solid state at room temperature.

具有刚性三三唑配体的蓝色发光银（I）配位聚合物的微波合成

摘要 2-氟-3,5,6-三(1H-1,2,4-三唑-1-基)-1,4-苯二甲腈 (L1) 与硝酸银 (I) 的微波辅助水热反应生成了配位聚合物 [Ag3(L2)2(NO3)] n (1)，其中 L2 配体 (HL2 = 2-hydroxy-3,5,6-tri(1H-1,2,4-triazol-1-yl) )对苯二腈)是通过从L1前体原位转化得到的。HL2 一水合物也已通过 L1 的微波介导水解分离并进行结构表征。单晶 X 射线衍射显示 HL2 一水合物包含两性离子 HL2 部分，而配合物 1 显示无限 L2 桥接双链结构。鉴于 HL2 分子有一个大的共轭 π 系统，配合物 1 在室温下固态呈现出强烈的蓝色发光。
