Influence of pH and Salt on the Photocrosslinking in Polyelectrolyte Thymine-Containing Films

Photocrosslinking of thymine-based water-soluble polymer films was investigated at varying preparation conditions. Adding salt or decreasing the pH of the solution from which the films were cast resulted in the decreased efficiency of photoimmobilization, while increasing the pH was found to increas...

Summary:Photocrosslinking of thymine-based water-soluble polymer films was investigated at varying preparation conditions. Adding salt or decreasing the pH of the solution from which the films were cast resulted in the decreased efficiency of photoimmobilization, while increasing the pH was found to increase the photoimmobilization efficiency. A mechanistic rationale for the observed effects is proposed.
