Mono-ketone modified C60s for acceptor materials in organic photovoltaic cells

We designed and synthesized methanofullerene derivatives with several types of thiophenyl mono-ketone for application in organic photovoltaic cells (OPVCs) as new accepter materials. The various mono-ketones having thiophene rings were substituted onto fullerene through application of Hirch-Bingel reaction under mild condition to compete with donor materials especially P3HT [Poly(3-hexylthiophene)] for nano-networking bulk-heterojunction structure where efficient light-induced charge separation is enable by a large-area donor-acceptor interface. The newly synthesized methanofullerene derivatives were characterized through 1H-NMR and FAB Mass spectroscopy. The compounds were also applied in OPV cell devices with P3HT as a donor material and measured electrochemical the property and power conversion efficiency.

Synthesis of 1,3,6,8-tetra-substituted pyrene derivatives and application of pyrene derivatives in organic field-effect transistors

The invention aims to develop synthesis of 1,3,6,8-tetra-substituted pyrene derivatives of the same category having semiconductor properties and application of the derivatives in organic field-effecttransistors. Series thiophene units are introduced into positions 1, 3, 6 and 8 of pyrene to construct the tetra-substituted pyrene derivatives, and material preparation is performed by utilizing a chemical reaction. Moreover, a silicon wafer serves as a gate, and the pyrene derivatives serve as organic semiconductor materials, so that bottom-gate top-contact field-effect transistors are prepared.R refers to the following groups as shown in the specification.

1,8-Substituted Pyrene Derivatives for High-Performance Organic Field-Effect Transistors

There have been many reports on the application of pyrene derivatives as organic semiconductors, but 1,8-subsituted pyrene semiconductors are less well-developed. Two p-type 1,8-substituted pyrene derivatives were synthesized that were composed of a pyrene core, thiophene or bithiophene arms, and end-capped octyl chains. These structures were not completely symmetrical and the dihedral angles between the pyrene core and the adjacent thiophene units had a difference of approximately two degrees. The field-effect performance of these materials was tested on a variety of dielectric surfaces. The performance of both materials with a spin-coated polystyrene layer on SiO2 (PS-treated SiO2) was better than that with an octadecyltrichlorosilane self-assembled monolayer on SiO2 (OTS-treated SiO2), which was mainly attributed to the presence of large grains on the low-leakage and high-capacitance PS films. The thiophene-contained compound presented a hole mobility of up to 0.18 cm2 V?1 s?1 on PS-treated SiO2, which was 45 times that of the bithiophene-contained compound, owing to less steric hindrance, high crystallinity, and large grain size.
