Fluorimetric Detection of Vapor Pollutants with Diketopyrrolopyrrole Polymer Microcavities.

ABSTRACT: The increasing prevalence and detrimental effects of volatile organic compounds are driving the need for selective on-site sensors that do not require complex sampling or instrumentation. Broadband selective sensors exhibiting selectivity based on their distinct response mechanism is becoming of increasing technological relevance in both industrial and urban settings. In this context, we propose a label-free sensor based on a polymeric planar microcavity embedded with a fluorescent organic dye, designed to detect various pollutants in the vapor phase. The sensor consists of alternating layers of cellulose acetate and poly(N-vinylcarbazole) and contains a polystyrene defect layer doped with a quadrupolar diketopyrrolopyrrole. Both the structural properties of the polymer microcavity
