Tavares, Ines G. published the artcileIntramolecular interchromophore singlet-singlet and triplet-singlet energy transfer in a metal-free donor-acceptor emitter, Name: tert-Butyl piperidin-4-ylcarbamate, the main research area is intramol interchromophore singlet triplet energy transfer donor acceptor emitter.
In this work we demonstrate the occurrence of singlet to singlet, and triplet to singlet, intramol. energy transfer between two thiophene-comprising donors (D) and a central perylene bisimide acceptor (A) covalently linked to each other trough a linker that separates the donor and acceptor moieties in a D-A-D structure. The designed metal-free organic tandem luminophore is herein designated as ARC-1467. Energy transfer from the excited triplet state of the thiophene donor to the singlet state of the perylene bisimide acceptor is observed in solution and in solid films of ARC-1467 dispersed in polystyrene. When the perylene bisimide acceptor is directly excited, the fluorescence decays with 4.9 ns lifetime. However, upon excitation of the donor unit in the near-UV region, delayed fluorescence of perylene bisimide with 5.7 μs lifetime is distinctly observed demonstrating the occurrence of energy transfer from the triplet state of the D unit to the perylene bisimide acceptor.
