A reaction strategy for the post-functionalization of hexavanadate derivatives is presented herein. In this study, five polyoxovanadate-based organic-inorganic hybrids TBA[VO{(OCH)CCOO(CH)CH}] (2), TBA[VO{(OCH)CCOO(CH)CH[double bond, length as m-dash]CH}] (3), TBA[VO{(OCH)CCOOCHCF}] (4), TBA[VO{(OCH)CCOO(CHCHO)CH}] (5), and TBA[VO{(OCH)CCOO(CH)OH}]·2CHCHOH (6) were successfully synthesized via esterification of carboxylic acid groups-containing TBA[VO{(OCH)CCOOH}] (1) with five alcohols possessing different functional groups. These hybrids were characterized by single crystal X-ray diffraction, IR, ESI-MS, H and C-NMR spectroscopies, and elemental analysis. Moreover, the formation of large vesicles was observed in a mixed solution of compound 2 due to its surfactant-like structure.
本文提出了一种六钒酸盐衍生物后功能化的反应策略。在本研究中，通过含羧酸基团的TBA[VO{(OCH)CCOOH}]（1）与五种具有不同官能团的醇进行酯化反应，成功合成了五种基于多钒酸盐的有机-无机杂化物TBA[VO{(OCH)CCOO(CH)CH}]（2）、TBA[VO{(OCH)CCOO(CH)CH[双键，长度为m-短划线]CH}]（3）、TBA[VO{(OCH)CCOOCHCF}]（4）、TBA[VO{(OCH)CCOO(CHCHO)CH}]（5）和TBA[VO{(OCH)CCOO(CH)OH}]·2CHCHOH（6）。这些杂化物通过单晶X射线衍射、红外光谱、电喷雾电离质谱、氢谱和碳谱核磁共振光谱以及元素分析进行了表征。此外，由于化合物2具有类似表面活性剂的结构，在其混合溶液中观察到了大囊泡的形成。
