Photoexcitations in polythiophene at high pressure
Physical Review B, 1993We report optical-absorption, photoluminescence (PL), and picosecond photoinduced absorption (PA) decay in films of poly-3-hexyl-thiophene at pressures up to 80 kbar. The spectral bands redshift nonlinearly with pressure and the PL intensity decreases markedly. Thermochromic transitions are completely inhibited at pressures as low as 14 kbar.

Optoelectronic Properties of Hyperbranched Polythiophenes
The Journal of Physical Chemistry B, 2011Branched conjugated architectures should possess the advantage of isotropic charge transport compared to conventional linear conjugated polymers, as for example poly(3-hexylthiophene) (P3HT) which is commonly used in organic solar cells. This contribution investigates the optoelectronic properties of branched poly(thiophene)s p3T and p4T synthesized in

A Versatile Approach to Affinitychromic Polythiophenes
Journal of the American Chemical Society, 2002The preparation of both postfunctionalizable and chromic poly[3-(N-succinimido-p-phenylcarboxylate(tetraethoxy)oxy)-4-methylthiophene] is reported. The N-hydroxysuccinimide ester side group can easily react with different amine-bearing molecules in the solid state to yield a library of new polythiophene derivatives.

This review reports the synthesis and the properties of chiral polythiophenes (PTs) and in particular it is focused on PTs bearing a sulfur atom directly bonded to the thiophene ring. These polymers show remarkable properties, related to their chirality and electrical conductivity and to the ability to interact with chiral molecules opening the ...

Preparation of Gold Nanoparticles on Ultrathin Films of Polythiophene and Polythiophene Derivatives
European Journal of Inorganic Chemistry, 2005AbstractTwo different methods were used to immobilise gold nanoparticles on ultrathin films of polythiophene and polythiophene derivatives. The first method utilised ultrathin films of polythiophene to prepare gold nanoparticles by direct reduction of HAuCl4.

In this study, polythiophene(PTP)/montmorillonite(MMT) nanocompositeswere synthesized by in situ intercalative polymerization and chemical oxidativepolymerization. In in situ intercalative polymerization method, compositescontaining 90 and 95% MMT were prepared. In chemical oxidativepolymerization method, a series of composites ranging from 1 to 15% by

Polythiophenes (PT) belong to the class of Conducting organic polymers and Conducting organic polymers that possess chirality present some unique opportunities when used as chiral substrates or as chiral electrode materials. The properties of chiral conducting PT can be tunable modifying the functional groups to the polymer backbone) and since these ...
