Abstract

A new molecule, 1,3,6,8-tetramethylpyrene (TMPY), with a similar shape to the luminescent material perylene has been successfully synthesized. The co-crystals with perylene doping have been grown and their crystal structure has been clarified by X-ray analysis. Optical spectra indicate that effective energy transfer has been achieved in the doping systems and the luminescence efficiency has reached as high as 78%. The pure TMPY shows p-type characteristics during the FET operation. The hole mobility is up to 0.26 cm2 V−1s−1.
