Fluorescent N-alkylated acrylamide copolymers and optical pH sensors

摘要：

A water-insoluble copolymer which is composed of (a) from 39.9 to 60% by weight of N,N-dimethylacrylamide or N,N-dimethylmethacrylamide; (b) from 60 to 39.9% by weight of N-alkylated acryl amides or N-alkylated methacryl amides; (c) from 0.1 to 0.7% by weight of a proton-sensitive fluorophore which is covalently bonded to the copolymer; and (d) from 0 to 20% by weight of a diolefinic crosslinking component. The copolymer is used in the form of a membrane on a transparent support material as an optical sensor for ionic strength-independent pH value determination.

摘要（中）：

由（a）39.9-60重量％的N，N-二甲基丙烯酰胺或N，N-二甲基甲基丙烯酰胺组成的水不溶性共聚物; （b）60〜39.9重量％的N-烷基化丙烯酰胺或N-烷基化甲基丙烯酰胺; （c）0.1〜0.7重量％的共价键共价键合的质子敏感荧光团; 和（d）0至20重量％的二烯烃交联组分。共聚物以透明载体材料上的膜的形式用作用于离子强度非依赖性pH值测定的光学传感器。
