Poly(2,3-dihexylthieno(3,4-b)pyrazine). A New Processable Low Band-Gap Polyheterocycle

Abstract

A new soluble, low band-gap polymer, poly(2,3-dihexylthieno3,4-B pyrazine), which is dark blue-black in the neutral state and which becomes transparent light yellow when doped has been prepared and studied. The preparation involves a multistep synthesis which involves condensation of 3,4- diaminothiophene with 7,8-tetradecanedione to produce 2,3-dihexylthieno3,4-B pyrazine which is polymerized with ferric chloride. Poly(2,3-dihexylthieno3,4-B pyrazine) has a doped film conductivity of 3.6 x 10-2 S cm-1 and a band-gap (film) of ca. 0.95 eV making it one of the lowest band-gap polymers prepared to date. Poly(2,3-dihexylthieno3,4-B pyrazine, Low Band-Gap, Conducting polymer, Processable.
