ABSTRACT

Cocrystal nanofibres of cobalt octaethylporphyrin and tetracyanoquinodimethane were prepared by a facile solution method and fully characterized by SEM, AFM, XRD, Raman, EDX, and UV-vis-NIR. The as-prepared cocrystal nanofibres had smooth surfaces and uniform dimension. When incorporated into prototype devices, they exhibited good photoresponse at ambient conditions. Additionally, the phototransistor characteristics with a maximum I(on)/I(off) ratio of -460 was demonstrated. The facile synthesis and good photoresponse may boost the potential applications of cocrystal-based nanostructures in future miniaturized devices.
