Abstract

We present the one-dimensional polymeric structures of [Cu(SePh)]_∞1 and [Cu(SeMe)]_∞2 that were solved by using powder X-ray diffraction data. Using a field-effect transistor (FET) set-up, the hole mobility of complex 1 was found to be 4 × 10⁻² cm² V⁻¹ s⁻¹, comparable to that of regioregular poly(3-hexylthiophene) (P3HT). Phase-pure orthorhombic and cubic Cu₂Se were synthesized from 1 as a single precursor under vacuum and inert atmosphere, respectively.
