Paper published 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 published 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.
