singlet fission process of organic molecules attached to neon clusters — •sharareh izadnia, aaron laforge, and frank stienkemeier — Institute of Physics, University of Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg, Germany

Charge and excitation transfer along with the corresponding decay and loss mechanism are fundamental aspects in light harvesting, organic photovoltaics, and optoelectronic devices.

In particular, singlet fission is a unique decay mechanism where a molecule excited to its singlet state can partially transfer its energy to a neighboring ground state molecule, and thereby create two molecules excited to a triplet state. As such, singlet fission can increase the efficiency of organic electronics and photovoltaic by creating multiple charge carriers from one single photon. Here, we report a systematic study of acene complexes attached to the surface of neon clusters. Depending on the system parameters, singlet fission and other lifetime reduction mechanisms are observed.
