Abstract This study investigates the critical role of polymer matrices in optimizing luminescence and energy transfer, utilizing commercial dyes Coumarin 6 (C6) Rhodamine B (RhB) as a donor‐acceptor pair. Solution‐phase experiments revealed dependence transfer efficiency on solvent dielectric constant. Furthermore, embedding within Poly(methyl methacrylate) (PMMA) or Poly(vinyl butyral) (PVB) significantly enhance due to increased molecular proximity. A modified approach for calculating overlap integral J(λ) was employed analyze solid state, providing insights beyond traditional Förster‐type calculations. Photostability studies demonstrated superior performance PVB films compared PMMA under exposure monochromatic (405 nm, 515 nm) white light irradiation. Finally, proof‐of‐concept device developed harness this enhanced light‐to‐electricity conversion, achieving maximum 7.28 %.

Published: Nov. 9, 2024

Artificial light-harvesting systems (LHSs) are of growing interest for their potential in energy capture and conversion, but achieving efficient fluorescence aqueous environments remains challenging. In this study, a novel tetraphenylethylene (TPE) derivative, TPEN, is synthesized co-assembled with poly(sodium 4-styrenesulfonate) (PSS) to enhance its via electrostatic interactions. The resulting PSS⊃TPEN network significantly increased blue emission, which further harnessed by an energy-matched dye, 4,7-di(2-thienyl)benzo[2,1,3]thiadiazole (DBT), produce LHS yellow emission. Moreover, system successfully applied develop color-tunable light-emitting diode (LED) devices. findings demonstrate cost-effective environmentally friendly approach designing tunable luminescent materials, promising future advancements energy-efficient lighting technologies.
