Acceptor Energy Offset Manages Ultrafast Recombination Dynamics in Donor-Acceptor Mixtures
We study charge recombination rates in blends of MEH-PPV and a comprehensive set of low molecular-weight fluorine-based acceptors, using visible-pump - IR-probe photoinduced absorption technique. The positions of acceptor’s HOMO-LUMO levels are engineered by addition of different chemical substituen...
