Perylene diimide–hydroxyphenyl benzothiazole–based new class of radical anions/dianions: biochemical assay for glucose detection

Abstract

We report the design, synthesis and characterization of a perylene diimide-hydroxyphenyl benzothiazole (BT-PDI) dyad as a new class for the formation of radical anion (BT-PDI˙⁻) and dianion (BT-PDI²⁻) in aqueous medium using H₂S. We demonstrate the applications of BT-PDI˙⁻ for (i) the detection of H₂O₂; (ii) the detection of glucose in blood serum using a biochemical assay and (iii) the reduction of Ag⁺ to Ag⁰.
