Uses
Used in chemical research. PTCDI is used extensively as an industrial pigment. It is used as tunable laser dye, light-harvesting material, transistor, molecular switched, solar cell, and optoelectronic device. Planar perylene- and naphthalene-based diimide linkers can be employed to tether the Watson- Crick and the Hoogsteen strands of a DNA triplex, thus providing conjugates capable of targeting singlestranded nucleic acids with the formation of hairpin triplexes.
