Regioregular P3HT (CAS 104934-50-1) is a popular low-bandgap polymer donor with applications in organic photovoltaics, polymer solar cells, OLEDs, and OFETs. Choose from different molecular weights and regioregularities across our range of P3HT to suit your specific research purpose.
The highest regioregularity P3HT (M1011, RR = 97.6%) produces highly crystalline films and is recommended for OFETs, nanofibril formation and fast drying OPVs at the thin interference peak (90 nm). For slow-drying, thick-film OPVs (>200 nm), lower molecular weight and regioregularity P3HT is recommended. These batches are well-suited to inkjet and other large-area or slow-drying deposition techniques where gelling, aggregation, and surface roughness need to be avoided.
All the P3HT available is highly soluble (50 mg/ml) in chlorinated solvents such as chloroform, chlorobenzene, dichlorobenzene and trichlorobenzene. Intermediate and lower molecular weight P3HT materials are recommended for use with non-chlorinated solvents such as xylene, toluene, and THF due to their increased solubility.

MSDS Documentation
P3HT MSDS sheetOFET Fabrication Guide
This procedure details the fabrication and charge mobility measurements for OFETs made from the M104 batch of P3HT. Field effect mobilities in excess of 0.12 cm2/Vs are recorded using M104 when the active layer is dispensed on OTS-treated silicon oxide dielectric by static spin coating from an optimized high/low boiling point solvent mix.
High hole mobility in conjunction with good solubility and partial air stability make regioregular P3HT a reference material of choice for both fundamental and applied research in organic electronic, physics and chemistry. As one of the most well-studied organic semiconductor, P3HT is often acknowledge to be one of the benchmark against which any new p-type or donor conjugate molecule should be compared and evaluated.
Mobility has previously been found to be positively correlated with increasing region-regularity, slow drying time (achieved using high boiling point solvent), lowering of the surface energy, and molecular weight in excess of 50 kD. These conditions favor p-p stacking parallels to the OFET substrate, which in turn results in improved charge transport across the transistor channel [1-13].
