Description

General description

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.

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.

Application

P3OT forms a nanocomposite with carbon nanotubes (CNTs) for devising a high performance semiconducting material. It can also be used as a π-conjugating polymer for the fabrication of organic electronic based devices which include polymeric diodes, solar cells and photovoltaic modules.

Conducting polymer.
Rechargeable battery electrodes, electrochromic devices, chemical and optical sensors, light-emitting diodes, microelectrical amplifiers, field-effect transistors and non-linear optical materials.

Used in organic field-effect transistors and in polymer-based solar cells.

Features and Benefits

Good processability, environmental stability and electroactivity.
