Regioregular poly (3-hexylthiophene-2,5-diyl), commonly known as P3HT (CAS number 104934-50-1), 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.

2011年7月11日 · It provides some guiding principles toward the crystallization control and morphogenesis of conjugated polymers such as regioregular (P3HT). This article will deal with (i) the structure and polymorphism of P3AT, (ii) chain folding, (iii) growth from solution, (iv) nucleation in thin films and (v) epitaxial orientation and nanostructuration.

研究发现，基于p3ht:trbtic的混合osc溶液在老化40分钟后，活性层共混物达到了最优化的相分离形貌，从而有利于激子解离和电荷传输，最终的设备pce达到了8.25%，这在目前看来仍然是很高的效率。

2024年6月5日 · The simple and cheap spray coating technology for the rr-P3HT polymer films deposition, complemented with fast low level humidity detection of the tested SAW sensors (much faster than the commercially available Michell SF-52 device), highlight their potential in a low-medium range humidity sensing application.

Regioregular poly (3-hexylthiophene) (RR-P3HT) nanotubes (200 nm in diameter) with tunable aspect ratios from 25 to 300 were prepared using a polymer melt wetting technique. Aspect-ratio tunability was achieved by controlling the wetting behavior of RR-P3HT melts in a template.

2021年4月1日 · In this paper, the effect of both molecular weight (MW) and regioregularity (RR) of the P3HT hole-transporting layer (HTL) on the stability of perovskite solar cells is thoroughly investigated. We synthesized four P3HT polymers, following different synthetic routes, to modulate both MW and RR.

2020年12月5日 · The insertion of H-H units in the rr-P3HT undoubtedly introduces intramolecular steric hindrances between adjacent hexyl chains forcing a local distortion of the originally coplanar thiophene units of rr-P3HT, thus producing a modulation of the Raman and UV–vis spectra.

2023年6月29日 · Alignment of conjugated polymers such as regioregular poly(3-hexylthiophene-2,5-diyl) (rr-P3HT) is an effective means to enhance charge transport and thermoelectric properties of thin films doped with F 4 TCNQ. In this contribution, we investigate the impact of P3HT regioregularity (RR) on the alignment achieved in thin films by high ...

2020年6月1日 · Fabrication of oriented large area thin films of RR-P3ATs with varying alkyl chain lengths by ribbon-shaped FTM. Optical anisotropy (DR) of the oriented thin films decreases as function of increasing alkyl chain length. Decrease in DR was explained by the enhanced alkyl chain interdigitation as evidenced by XRD.

2014年1月1日 · The first major improvement in hole mobility was achieved by using highly regioregular head-to-tail P3HT (rr-P3HT) instead of the previously used regio-random P3HT . This advance was made possible by a new synthetic route now known as the McCullough method, which enabled high yields of head-to-tail P3HT [ 20 , 21 ] and the observation of ...
