Abstract:
A new thiophene-based salphen-type ligand, 1, and its Cu(II) and Zn(II) complexes, 1 center dot Cu and 1 center dot Zn center dot MeOH, were designed and synthesized. These metal organic complexes (MOCs), with ultra-close p-stacking interactions were explored as a novel class of active materials for organic field effect transistors (OFETs). The top-contact bottom gated OFETs fabricated from solution-processed thin films of 1 center dot Cu and 1 center dot Zn center dot MeOH exhibited excellent p-type mobilities (up to 0.7 and 1.5 cm(2) V-1 s(-1), respectively).
