Cover illustration: Electron donor–acceptor molecules play an important role in the understanding of charge-transfer processes. In the compound C24H19N, the electron donor N,N-dimethylaniline (DMA) is covalently linked to the electron acceptor pyrene (Py). The structural and physical characteristics of these donor and acceptor groups strongly influence the electron-transfer mechanism, which leads to unusual absorption and emission spectra in the optical regime of PyDMA, making it a molecular diode in which electron-donor and electron-acceptor moieties are twisted against each other, thus modulating the electron charge-transfer processes. The dimethylamino group is inclined to the benzene ring by 2.81 (9)°. The mean plane through these groups makes a dihedral angle of 64.12 (2)° with the mean plane of the pyrene ring system.

Research communications

Research communications are designed to help authors bring out the science behind their structure determinations. Authors are encouraged to report more than one structure in the same communication and also to include the results of investigations with other techniques. The Research communications format makes Acta E the natural home for structure determinations with interesting science to report.

Emerging Sources Citation Index
