Abstract: Two novel aromatic thiophene-containing annulated compounds, viz. 2-methoxy[b]naphtho[2,1-d]thiophene and 1,3-dimethoxy[b]naphtho[2,1-d]thiophene, were synthesized via the Mallory-type photocyclization. Their optical, redox and photophysical properties have been studied along with phosphorescence spectra and lifetimes at 77 K. The first compound exhibited much higher charge mobility in thin films than the second one suggesting the former being prospective for molecular electronics applications

Keywords: photocyclization, naphthothiophene, organic electronics, luminescence, charges carrier mobility.
