It has now been more than 30 years since buckminsterfullerene became a real thing. An exclusive field of study called fullerene chemistry arises and is discovered to be unique in many respects. In a very short time, a great deal of effort has been devoted on the fullerene chemistry and properties of fullerene derivatives. The fields of fullerene and light-induced processes considerably overlapped, and now numerous wonderful examples are on exhibition. The large number of these systems has been designed to take advantage of the electron-accepting property of fullerene and broadcasts the fullerenes as universal spin converter advertising its perfect intersystem crossing (ISC) quantum yield where a spin converter can be identified as a chromophore that undergoes efficient ISC with a low first excited state (S1), but does not necessarily strongly harvest visible light. Thus, donor-acceptor systems in the field of light-induced processes within multicomponent fullerene arrays have been proposed as models for optical limiters, owing to the singlet oxygen production efficiency of C60 and the C60 derivatives in the field of medicinal chemistry.
