structure of 3 (space group R3¯). The PU has pseudo trigonal symmetry in picolinoxy triazine 4 (space group P21/n). In contrast to the phenyl derivatives, the extended aryl arms in biphenyl 5 do not adopt a trigonal conformation: two biphenyl groups are oriented parallel that participate in Br…Br and Br…π interactions. We note that 1 and 2 readily form hexagonal host lattices for guest inclusion, while 3
摘要 2,4,6-Tris(4-halophenoxy)-1,3,5-triazine 1 是一种方便的 C3 起始材料,用于通过卤素…卤素三聚体合成子和 π 堆叠介导的六边形开放框架自组装皮德福特单位(PU)。我们在本文中研究了 2,4,6-tris(2-iodo-3-pyridyloxy)-1,3,5-triazine 2 , 2,4,6-tris(3-iodophenoxy)-1,3 的晶体结构,5-triazine 3 , 2,4,6-tris(6-methyl-3-pyridyloxy)-1,3,5-triazine 4 , and 2,4,6-tris[4-(4'-bromophenyl) phenoxy )]-1,3,5-三嗪 5 。三嗪 2 在菱面体空间群 R3¯ 中形成同构 2:1 主体·客体加合物(客体 = 均三甲苯,可力丁),使得主体结构由 C3i-PU 和 C─H…N
