Abstract:

The exposure of solutions of 6,13-dithienylpentacenes to sunlight in air afforded their endoperoxides. The solutions and thin films of the endoperoxides were irradiated with UV light to reproduce the 6,13-dithienylpentacenes. These conversions are of interest as an ecological film-formation technology in the study of organic semiconductors.
