metal–organic frameworks (MOFs) have been synthesized using Sr(NO3)2 and the organic linkers 2-nitro-[1,1′-biphenyl]-4,4′-dicarboxylic acid (H2bpdcNO2) and 2,2′-dinitro-[1,1′-biphenyl]-4,4′-dicarboxylic acid (H2bpdc(NO2)2). The structures of [Sr(bpdcNO2)2(DMF)2(H2O)2] (WUF-15; WUF = Wollongong University Framework) and [Sr4(bpdc(NO2)2)4(DMF)2(H2O)4·2DMF] (WUF-16) were determined by single crystal X-ray
使用Sr(NO 3)2和有机连接基2-硝基-[1,1'-联苯] -4,4'-二羧酸(H 2 bpdcNO 2)和2,2'-二硝基-[1,1'-联苯] -4,4'-二羧酸(H 2 bpdc(NO 2)2)。[Sr(bpdcNO 2)2(DMF)2(H 2 O)2 ](WUF-15; WUF =卧龙岗大学框架)和[Sr 4(bpdc(NO 2)2)4(DMF)2(高2O)4 ·2DMF](WUF-16)是通过单晶X射线衍射(SCXRD)测定的,由无限量的羧酸锶SBU组成,并包含大正方形(〜18Å)和较小的三角形通道(〜9Å)取向彼此平行并带有硝基官能团。H 2 bpdc(NO 2)2原位配体转化为苯并[ c ]喹啉-3,8-二羧酸(H 2 bc)并形成式[Sr(bc)(H 2 O )的无孔配位聚合物)2 ](WUF-17)与有趣光致发光性质被发现了。H 2的独立合成bc使制备适合SCXRD结构
