摘要
研究了含吡啶丙烯酰胺与n -乙烯基吡咯烷酮(VP)或n -异丙基丙烯酰胺(IPA)共聚物中邻苯酞染料Ni(II)配合物的热致变色性。共聚物中悬垂的吡啶基团影响显色的灵敏度和色种的稳定性。VP与2-丙烯酰胺- n -3-吡啶基丙酰胺吡啶的共聚物对温度有较大的依赖性,而n -3-吡啶基丙酰胺与IPA的共聚物颜色稳定。
Thermochromism of metallophthalein in acrylamide copolymers with pendant pyridine substituents
The thermochromism of Ni(II) complexes of cresolphthalein dye was studied in pyridine-containing acrylamide copolymers with N-vinyl-pyrrolidone (VP) or N-isopropylacrylamide (IPA). Pendant pyridine moieties in the copolymers affect the sensitivity of color development and stability of color species. A large temperature dependence was obtained in the copolymer 2-acrylamido-N-3-pyridylpropanoamide pyridine with VP and the developed color was stable in copolymer of N-3-pyridylacrylamide with IPA.
