Acyl derivatives of 2-aminopyridine, 2-aminopyrimidine, 4-amino-2,2,6,6-tetramethylpiperidine-1-oxyl, and 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl were obtained from long-chain diacetylenic acyl chlorides and the corresponding heterocyclic compounds. Spreading isotherms of monolayers on a water surface show that lengthening of the hydrocarbon chain and replacement of the pyridyl groups in these
2-氨基吡啶、2-氨基嘧啶、4-氨基-2,2,6,6-四甲基哌啶-1-氧基和4-羟基-2,2,6,6-四甲基哌啶-1-氧基的酰基衍生物获自长链二炔酰氯和相应的杂环化合物。在水表面上展开单层的等温线表明,烃链的延长和这些化合物中的吡啶基被更亲水的嘧啶基取代,使膜更加凝聚。硝酰基自由基的长链酰基衍生物形成具有低塌陷压力的单层。记录了这些自由基在光聚合之前和之后的 Langmuir-Blodgett 膜的 ESR 光谱。
