This article reports two discoveries. (1) 2-Methoxyethanol induces unprecedented selectivity for etherification of 5-hydroxy-2-nitrobenzic acids without forming undesired esters. (2) Such compounds are precursors for amides showing unusual robustness against oxidative degradation, essential for molecular electrets that transfer strongly oxidizing holes at about −6.4 eV vs. vacuum.
本文报告了两个发现。(1) 2-甲氧基
乙醇对 5-羟基-2-硝基
苯甲酸的醚化具有前所未有的选择性,而不会形成不需要的酯。(2) 此类化合物是酰胺的前体,显示出不同寻常的抗氧化降解能力,这对于在约 -6.4 eV与真空条件下转移强氧化空穴的分子驻极体至关重要。
