This is a computational chemistry study in designing singlet fission chromophores based on a diazadiborine framework. Substitutions and additions are proposed to enhance diradical character of the diazadiborine so that the designed molecules satisfy the two energy criteria for singlet fission. Synthesizability of the designed molecules is discussed.

The Subject

Singlet fission, a multiple exciton generation process, can revolutionize existing solar cell technologies. Offering the possibility to double photocurrent, the process has become a focal point for physicists, chemists, software developers, and engineers. The following review is dedicated to the female investigators, predominantly theorists, who have contributed to the field of singlet fission. We highlight their most significant advances in the subject, from deciphering the mechanism of the process to designing coveted singlet fission materials.
