poly(3-hexylthiophene)

polymer

Poly(3-hexylthiophene), or P3HT, is a conjugated organic polymer belonging to the polythiophene family, characterized by a regular backbone of thiophene rings with alkyl side chains that enhance processability and crystallinity. It is widely used in organic electronics research and commercial applications, particularly in organic photovoltaic (OPV) solar cells, organic field-effect transistors (OFETs), and organic light-emitting devices (OLEDs), where its semiconducting properties and tunable bandgap make it valuable for lightweight, flexible, and solution-processable devices. P3HT remains a benchmark material in the organic semiconductor field due to its good charge mobility, relative stability, and decades of optimization experience, though it is increasingly combined with fullerene or non-fullerene acceptors in modern high-efficiency solar cell designs.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
