Theobromine and direct arylation: a sustainable and scalable solution to minimize aggregation caused quenching

Author affiliations

Abstract

A green and scalable method to synthesize organic luminophores with minimal aggregation caused quenching (ACQ) is reported where direct arylation is used to attach alkylated theobromine moieties onto luminophores. The resulting compounds demonstrated high photoluminescence quantum yields (PLQYs) in solution and as aggregates. The minimized ACQ can be ascribed to the large dihedral angles that theobromine moieties introduce into these molecules, preventing π–π interactions between the luminophores. Furthermore, the large dihedral angles promote the formation of hybridized local and charge-transfer states in these molecules. Finally, amplified spontaneous emission measurements were performed to explore their potential in lasers.
