Description

General description

C8-BTBT is a conducting polymer with [1]benzothieno[3,2-b][1]- benzothiophene (BTBT) as the base material for the development of air-stable semiconductors. It can form a spin coated thin film that can be used as a p-type semiconductor with charge mobility of 43 cm2V-1s-1. It exhibits highly ordered self-assembled monolayer (SAM) on graphene and hexagonal boron nitride (hBN).

Application

C8-BTBT is a conjugating polymer that can be used in a variety of organic electronics based applications which includes organic photovoltaic cells (OPV), organic light emitting diodes (OLEDs) and organic thin film transistors (OTFTs).

High field-effect mobility of 5.5-5.7 cm2/Vs and high On/Off ratio of 109 ; solution-processed (solubility of 80 mg/mL) OFETs

Packaging

100, 250 mg in glass insert
