Regioregular poly(3-hexylthiophene-2,5-diyl). Commonly known as P3HT.
The highest regioregularity P3HT (M104, RR = 96.3%) produces highly crystalline films and is recommended for OFETs, nanofibril formation and fast drying OPVs at the thin interference peak (90 nm). However, the exceptionally high regioregularity of this P3HT means that gelling and surface roughness can be an issue for slow-drying thick-film OPVs (>200 nm). Lower molecular weight and regioregularity P3HT is recommended for inkjet and other large area or slow drying deposition techniques where gelling/aggregation and surface roughness need to be avoided.
A fabrication report with mobility measurements of 0.12 cm2/Vs for M104 can be found below.
All the P3HT below is highly soluble (50 mg/ml) in chlorinated solvents such as chloroform, chlorobenzene, dichlorobenzene and trichlorobenzene. The 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.
Regioregular poly(3-hexylthiophene-2,5-diyl), commonly known as P3HT, is a popular low band gap polymer donor with applications in organic photovoltaics, polymer solar cells, OLEDs and OFETs. We sell a full range of P3HT with different molecular weights and regioregularities for a variety of research purposes. Produced by Merck KGaA, this high quality P3HT collection allows a wide range of science and engineering to be undertaken.
