An axially chiral binuclear μ-hydroxo Pd complex (BPHP) first served as an excellent chiral sensor for discriminating a variety of analytes including amino alcohol, amino amide, amino acid, mandelic acid, diol, diamine, and monoamine by 31P1H} NMR. A detailed recognition mechanism was proposed based on the single crystal and mass spectrum of Pd-complexes. In general, BPHP sensor, through extracting
轴向手性双核μ-羟基Pd络合物(BPHP)首先是出色的手性传感器,可通过31 P 1 H来区分各种分析物,包括氨基醇,氨基酰胺,氨基酸,扁桃酸,二醇,二胺和单胺NMR。基于单晶和钯络合物的质谱,提出了一种详细的识别机理。通常,BPHP传感器通过其Pd-OH基团提取分析物的酸性氢,与分析物的两个对映异构体形成稳定的非对映异构体复合物,从而为手性鉴别提供了可分辨的31 P 1 H} NMR分离信号。
