The donor-acceptor interface is a research area that focuses on the interaction between two molecules or materials, one acting as a donor and the other as an acceptor. This interaction typically involves the transfer of electrons or energy between the donor and acceptor, leading to various important phenomena such as charge transfer, energy transfer, and exciton formation. Researchers in this field aim to understand the fundamental mechanisms underlying these interactions, as well as to develop new materials and devices based on donor-acceptor interfaces for applications in areas such as organic electronics, photovoltaics, and sensors.
