Mild selective photochemical oxidation of an organic sulfide using OxP-polyimide porous polymers as singlet oxygen generators.

ABSTRACT: A series of porous organic polymers based on a singlet oxygen generating oxoporphyinogen ('OxP') has been successfully prepared from a pseudotetrahedral OxP-tetraamine precursor (OxP(4-NH₂Bn)₄) by its reaction with tetracarboxylic acid dianhydrides under suitable conditions. Of the compounds studied, those containing naphthalene (OxP-N) and perylene (OxP-P) spacers, respectively, have large surface areas (~530 m² g^-1). On the other hand, the derivative with a simple benzene spacer (OxP-B) exhibits the best ¹O₂ generating capability. Although the starting OxP-tetraamine precursor is a poor ¹O₂ generator, its incorporation into OxP</
