A two-phase radical polymerization was applied for the synthesis of fullerenecontaining poly(4-vinylpyridine), which were used as polyelectrolytes in the fabrication of photovoltaic devices. Two-phase radical polymerization resulted in the products of poly(4-vinyl pyridinated) fullerenes (PVPyF) containing a high fullerene content and poly(4-vinylpyridine) arms of short length. These polyelectrolytes with a C 60 content of up to 35% by weight are soluble in organic solvents and water at a low pH. High efficient photoinduced charge transfer in samples of PVPyF and polyanionic polythiophene derivatives fabricated by the electrostatic layer-by-layer deposition technique in producing self-assembled multilayers (SAMs) was demonstrated. As a result, high response to the increase of photoinduced conductivity was observed on the 75 bilayer device of PVPyF-3 + /H-PURETupon irradiation. Photoconductivity was found to increase in more than one order of magnitude from 0.024 to 0.31 S/cm at an applied voltage of 1.0 volt. The sign of short-circuit photocurrent was consistent with electrons flowing from Al electrode towards the ITO modified substrate.

“…PPV precursor was synthesized via tetrahydrothiophene (THT) route [11 ]. Sulfonated polyaniline (SPAn) was synthesized using the procedure described by Epstein et al [12] and poly(thiophene-3-acetic acid) (PTAA) was prepared by the ferric chloride polymerization of ethyl thiophene-3-acetate (Lancaster Synthesis) followed by acid hydrolysis of the ester group [13]. Polyallylamine hydrochloride (PAH) (MW = 28,000 g/mole) and sulfonated polystyrene (SPS) (MW = 70,000 g/mole) were used without further purification (from Aldrich Chemical).…”

Multilayer thin film heterostrutuctures comprised of alternating layers of a poly(phenylene vinylene) (PPV) precursor and various polyanions were fabricated using a new self-assembly technique. Thermal treatment of these films produced multilayers of the fully conjugated form of PPV. Alternating multilayers fabricated with inert polyanions such as sulfonated polystyrene exhibited a very strong photoluminescence whereas alternating multilayers fabricated with electron acceptor polyanions such as sulfonated C60 and poly(thiophene acetic acid) displayed a highly quenched luminescence. This latter behavior suggests that self-assembled multilayers can be used to examine photoinduced charge transfer interactions between PPV and various electron acceptors.

“…Amongst the preparation methods for thin films of soft materials, the Layer-by-Layer (LbL) self-assembly technique has received recent attention partly due to its experimental simplicity, and because it enables studies of molecular interactions between a wide variety of materials [3,4]. In addition, when working with materials in the form of thin films, rather than as powder or solution, it is possible to obtain highly organized structures at the molecular level and controlling the thickness of according to the purpose of study or application for the film.…”
