Donor-Acceptor Groups (DAGs) are a class of molecular species composed of a donor unit and an acceptor unit. These units are typically part of a larger molecular framework, and are arranged in a specific manner to facilitate the transfer of electrons. The donor and acceptor units are often characterized by their ability to donate or accept electron density, respectively.

The donor unit is usually a strongly electron-donating functional group, such as an amino or ethynyl group, which can donate a pair of electrons to an acceptor. The acceptor unit, on the other hand, is typically a strongly electron-withdrawing functional group, such as a nitro or cyano group, which can accept an electron pair from a donor.

Cisoid and transoid arrangements of DAGs have been studied extensively, with the cisoid arrangement showing a higher degree of electronic coupling between the donor and acceptor units. This increased electronic coupling is thought to be responsible for the observed increase in reactivity and catalytic activity of DAGs in certain reactions.

DAGs have been found to exhibit a number of unique properties, including high electron transfer rates and selectivity for specific reaction partners. These properties make DAGs useful in a variety of applications, including electrocatalysis, energy storage, and biomedical sensing. Further research is ongoing to fully elucidate the potential uses and limitations of DAGs.
