Back-and-Forth Energy Transfer during Electronic Relaxation in a Chlorin-Perylene Dyad

Autor: Sergei Tretiak, Victor M. Freixas, Johan F. Galindo, Sebastian Fernandez-Alberti

Publikováno v: The journal of physical chemistry letters. 12(42)

Donor-acceptor dyads represent a practical approach to tuning the photophysical properties of linear conjugated polymers in materials chemistry. Depending on the absorption wavelength, the acceptor and donor roles can be interchanged, and as such, th
