Description générale

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) with sheet resistance: <1,000 ohm/sq

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

High Crystalline, Solution-Processable Organic Field-Effect Transistors

Dr. Chan and researchers highlight flexible transistors are the building blocks of next-generation soft electronics. Among all the reported material systems that can be fabricated by researchers, such as circuits, biosensors, stretchable displays, and others,1–5 small molecular weight organic semiconductors are among the most promising candidates for flexible transistor applications. For these small molecular weight organic semiconductors, the semiconductor forming the conductive channel dominates the device performance.

Polymer Semiconductors for Intrinsically Stretchable Organic Transistors

Intrinsically stretchable active layers for organic field-effect transistors (OFET) are discussed. Polymer structural modification & post-polymerization modifications are 2 methods to achieve this.
