Towards understanding the competition of electron and energy transfer in “molecular” nanographenes on the example of hexa-peri-hexabenzocoronene
Beneventi, G. M., Krug, M., Reger, D., Jux, N., Guldi, D. M., Journal of Photochemistry and Photobiology C: Photochemistry Reviews 2023, 56, 100602. https://doi.org/10.1016/j.jphotochemrev.2023.100602 Bottom-up strategies have allowed the synthesis of “molecular” nanographenes with full control over size, shape and functionality. In recent years, the progress on wet chemical approaches, oxidative cyclodehydrogenation amongst all, has […]Beneventi, G. M., Krug, M., Reger, D., Jux, N., Guldi, D.
