in acidic or basic solutions (in a pH range from 4 to 12). Moreover, catalytic measurements show that compound 1 is an excellent heterogeneous catalyst for the selective oxidation of aryl alkenes to aldehydes or ketones with conversions of 97%.
三嗪衍生物是一类具有高光化学活性和优异发光特性的缺电子π共轭分子,已被用作一种电子受体,用于构建分子笼、发光和光致变色材料。在本文中,一种新型且高度稳定的 MOF 具有类立方体簇 [Co 4 (SO 4 ) 3 (F) 3 (tpt) 2 (tatb)] ( 1 ) (tpt = 2,4,6-tris- (4-吡啶基)-1,3,5-三嗪,H 3tatb = 4,4',4''-(1,3,5-triazine-2,4,6-triyl)tribenzoic acid),基于三嗪衍生物成功合成,具有前所未有的硫酸盐和氟化物-桥接立方型四核钴簇和 3D + 3D → 3D 开放框架。化合物1显示出相当高的 BET 表面积,并在普通溶剂中甚至在酸性或碱性溶液(pH 范围为 4 至 12)中表现出优异的热稳定性和高化学稳定性。此外,催化测量表明,化合物1是一种极好的多相催化剂,用于将芳基烯烃选择性氧化为醛或酮,转化率为
