Amino-substituted phenol red as pH indicator and process |
| abstract |
(57) [Summary] [Object] To provide an indicator and a support that can be easily and easily immobilized on the tip of an optical fiber and maintain sensitivity over a wide pH range for a long time, and a method for producing the same. On the sulfonated ring, preferably 4- Nitrogen-containing phenol red compounds containing amino or nitro groups substituted in position, ie para to the central carbon. This allows the dye to be covalently bonded to the polymeric support with minimal interaction with the dye functional groups and minimal intramolecular interaction with the polymeric support. This compound is useful as a physiological pH indicator and can be placed at the tip of an in vivo fiber optic sensor. Synthetic methods are described that give compounds of high purity. Novel indicator binding polymers and blends of indicator binding polymers with a second ionic polymeric material are also described, which provide compositions with selectively varying apparent pKa, hydrophilicity and ion permeability. |
