Abstract: Since the discovery of donor-acceptor (D-A) type molecules in the field of material science, they have found great applicability in the field of photocatalysis. Most of these compounds are based on complex D-A-D structures or multi-D-A systems, such as the 4CzIPN. Whereas these systems have been widely studied and applied as photocatalysts, simpler D-A structures remain less explored. Nevertheless, the simplicity of D-A structures makes them the ideal structures to further understand the structure-property relationship of donor-acceptor (D-A) molecules for optimizing their photocatalytic performance by simpler modification of the different D-A subunits. In particular, D-A structures featuring sulfur-based acceptors and nitrogen donors have gained increasing attention for their use as photoredox catalysts. This study introduces a new family of D-A molecules by exploring various sulfur-based acceptors and nitrogen donors, including a novel tribenzo[b,d,f]azepine (TBA) unit and 5H-dibenz[b,f]azepine (IMD). Our findings demonstrate that these simple D-A structures exhibit promising photocatalytic properties, comparable to those of more complex D-A-D systems.
