Abstract:
Following a report that highlights the importance of intramolecular hydrogen bonds for improved NIR-TADF efficiency in CAT-1 [Leng et al., J. Phys Chem. A, 2021, 125, 2905], an intramolecularly doubly hydrogen-bonded base design is investigated and compared to singly and non-bonded derivatives. It is found that the potential to form more intramolecular hydrogen bonds correlates with decreasing internal reorganization energies in most of the designed structures. In addition, our proposed base design facilitates the desired interlocking of charge transfer donor-, linker- and acceptor-planes through steric gauche-interactions to both linker-plane sides, allowing to trap also smaller heterocyclic linkers.
