Abstract:Discerning the impact of the coherent motion of the nuclei on the timing and efficiency of charge transfer at the donor−acceptor interface is essential for designing performance-enhanced optoelectronic devices. Here, we employ an experimental approach using photocurrent detection in coherent multidimensional spectroscopy to excite a donor aromatic macrocycle and collect the charge transferred to a 2D acceptor layer. For this purpose, we prepared a cobalt phthalocyanine-graphene (CoPc−Gr) interface. Unlike blen… Show more
