23_25i/2013Photochemistry: Photochemical Transformation of Fullerenes (Adv. Funct. Mater. 25/2013)

On page 3220 Ludvig Edman and co-workers report that the efficiency of the photochemical monomer-to-dimer transformation of the fullerene [6,6']-phenyl-C61-butyric acid methyl ester (PCBM) is strongly dependent on the light intensity. This information is used to demonstrate that direct patterning of electronically active PCBM films can be effectuated by subsecond UV-light exposure. It is demonstrated that the fullerene dimer formation must constitute a bi-excited reaction between two neighboring monomers photoexcited to the triplet state.
