Abstract

Molecular materials formed from aggregated TDBC dye and PVA have been shown to have high, metal-like reflectivity. This property enables them to support a surface exciton polariton mode, despite their inherent disorder [1]. Here we build on this work, showing first that several dyes have these properties, and second that these properties can be controlled in fabrication. These new materials could be used to create novel nanophotonic modes [2], with choice of dye and method of fabrication giving control over the guided mode. The quantum behaviour of these materials is also of interest. The strong intermolecular coupling present in J-aggregates produces a delocalised exciton ground state that could facilitate coherent energy transport [3].
