P(g2T-T)

CAS Number 1974310-62-7

High Performance Stretchable Redox-active Semiconducting Polymer

Highly desirable for organic electrochemical transistors (OECTs)

Specifications | MSDS | Literature and Reviews

P(g2T-T) is polythiophene derivative functionalized with methoxy-terminated triethylene glycol (TEG) chains. Polythiophene backbone allows for chain flexibility, and polar triethylene-glycol side chains for the penetration of hydrated ions.

P(g2T-T) is a high-performance stretchable redox-active semiconducting polymer (RASP) highly desirable for organic electrochemical transistors (OECTs), i.e. bioelectronics. With great stretchability and skin-like softness compatibility, P(g2T-T) has the great potential to achieve seamless tissue–electronics interfaces for accurate signal acquisition in on-skin electrocardiogram (ECG) recording.
