Abstract
A binary (1?:?1) charge transfer cocrystal composed of 1-aminopyrene and 7,7′,8,8′-tetracyanoquinodimethane (TCNQ) is expected to possess potentially intriguing n-type semiconductor properties. The cocrystal was characterized by single crystal analysis, electrical conductivity measurements and spectroscopic methods including EPR, IR and UV-vis in the solid state. The supramolecular features and origin of semiconductor nature of the cocrystal were explored by theoretical studies with a special emphasis given on the effect of amino substitution. The estimated degree of charge transfer (?0.24e) in the cocrystal is predictive of its substantial transport ability for electrons under ambient conditions.
