Abstract

We report the use of optofluidic hollow-core photonic crystal fibres as microreactors for Stern-Volmer (SV) luminescence quenching analysis of visible-light photocatalytic reactions. This technology enables measurements on nanolitre volumes and paves the way for automated SV analyses in continuous flow that minimise catalyst and reagent usage. The method is showcased using a recently developed photoredox-catalysed α-C-H alkylation reaction of unprotected primary alkylamines.
