New paper out in ACS Appl. Polym. Mater.

Congratulations to current and former group members Morton and James whose paper entitled “Luminescent Solar Concentrators Based on Energy Transfer from an Aggregation-Induced Emitter Conjugated Polymer” has been accepted for publication in ASC Applied Polymer Materials.

This work reports a multilumophore LSC design that circumvents the problems of incomplete solar harvesting and aggregation-caused quenching through a combination of nonradiative Forster resonance energy transfer (FRET) and aggregation-induced emission (AIE): this LSC system incorporates a green-emitting polymeric AIEgen, named poly(tetraphenylethylene), as an energy donor, and a red-emitting perylene bisimide molecular dye (PDI-Sil) as the energy acceptor, within an organic-inorganic hybrid diureasil waveguide. The FRET process was shown to occur from p-O-TPE to PDI-Sil, resulting in an internal photon efficiency of 20% at optimised donor-acceptor ratio, demonstrating a viable design for LSCs ultilizing AIE-based FRET approach to improve the solar-harvesting performance.
