Synthesis and properties of 4,4′-bis[5-alkyl(aryl)benzoxazol-2-yl]-2-hydroxy(alkoxy)biphenyls
摘要:
Synthesis of 2-hydroxy(methoxy)-4,4'-biphenyldicarboxylic acids was developed. Based on their reactions with o-aminophenols we prepared for the first time 4,4'-bis[5-alkyl(aryl)benzoxazol-2-yl]-2-hydroxy-(alkoxy)biphenyls, which might be of interest as luminescent dyes. Hydroxy compounds in a salt form possess abnormally high Stokes shift.

Photolabile groups can be incorporated into metalâorganic frameworks (MOFs) and then quantitatively cleaved following MOF formation. Here, a 2-nitrobenzyl ether prevents lattice interpenetration (catenation) in a cubic MOF derived from zinc(II). Subsequent photolysis unmasks a hydroxyl group, and produces an open MOF that cannot be synthesized directly.

we report coupling in situ high temperature postsyntheticmodifications (PSMs) in metal–organicframeworks (MOFs). Thermo-reactive propargyloxy-functionalized zinc IRMOFs (isoreticular metal–organicframeworks) prepared from 2-(prop-2-yn-1-yloxy)-[1,1′-biphenyl]-4,4′-dicarboxylic acid (H2bpdcOCH2CCH) were investigated for their high-temperature postsynthetic rearrangement (PSR) chemistry to heterocyclic
在这里,我们报告了金属有机框架(MOF)中的原位高温合成后修饰(PSM)的耦合。由 2-(prop-2-yn-1-yloxy)-[1,1'-联苯]-4,4'-二羧酸 (H 2研究了bpdcOCH 2 CCH) 对杂环色烯和苯并呋喃的高温合成后重排 (PSR) 化学反应,然后与分子氧进行固气反应。与酯化合物 Me 2 bpdcOCH 2的常规熔体反应相比,在多孔 MOF 环境中发现初始分子重排的选择性是倒置的CCH 并且比从 H 2 bpdcOCH 2 CCH的固态转化更容易进行,这表明 MOF 有可能产生不同的化学反应。主要的氧化过程是色烯环的热解,具有烯丙基型氧化的次要途径,以产生杂环色烯酮官能团。该序列在一系列由热反应 H 2 bpdcOCH 2 CCH 和耐热 H 2制备的双组分多元 IRMOF 框架上也取得了成功bpdCOMe 接头,证明这些反应可以与已知的晶体工程策略一起使用。正如表面积分析和
