Abstract
The molecular surgical approach, involving creation of an orifice on the empty fullerene cage, insertion of a small guest through the orifice, and closure of the orifice with retention of the guest, is a promising method to synthesize yet-unknown endohedral fullerenes. Herein wereport the synthesis of H2O@C60 with dynamic control of the orifice-size under mild conditions as well as application of open-cage C60 derivatives to organic photovoltaic devices.
