Description
Poly(3-octylthiophene-2,5-diyl) (P3OT) is an alkylthiophene based conductive polymer with high electroluminescence. It is soluble in most of the organic solvents and can be prepared by the electrochemical polymerization of 3-octylthiophene (3OT). It has hydrophobic properties and can be used as a transducer for ion selective electrodes.
Poly(3-alkylthiophene)s exhibit thermo- and solvatochromism. Regiorandom poly(3-octylthiophene) shows relatively weak red PL in dilute solution. The emission is largely quenched in concentrated solutions and solid thin films.1:1 (head-to-head):(head-to-tail) linkages of regioisomers.
