Isomeric pyridyloxalamide derivatives 1–3, which differed in the position of the nitrogen atom on the pyridyl ring, showed remarkably different gel‐forming aptitudes in the presence of CuCl2 salt in alcohols. Whilst derivatives 1 and 3 formed a soluble complex and a solid precipitate, respectively, ligand 2 generated a remarkably metal‐ and anion‐specific metallogel.
异构体pyridyloxalamide衍生物1 - 3,其不同在吡啶环上的氮原子的位置,显示出显着不同的凝胶形成性向在CuCl存在下2盐在醇中。衍生物1和3分别形成可溶的络合物和固体沉淀物,而配体2则产生显着的金属和阴离子特异性金属对苯二酚。
