Abstract: The organic semiconductor polymers relates to the synthesis of a carbazole-based ladder polymer. The synthesis of the ladder polymer includes forming a precursor conjugated polymer by Suzuki step growth polymerization of 2,7-dibromocarbazole with 1,4-dibromo-2,5-divinylbenzene, followed by end capping with 2-bromostyrene and 2-vinyl-phenylboronic acid. Then, the pendent vinyl groups are closed by ring-closing olefin metathesis to obtain the ladder polymer.

Abstract: A polypentenamer-silica composite can include a surface-modified silica compound and a polypentenamer chain grafted onto the surface-modified silica compound. The polypentenamer has physical properties similar to natural rubber. The polypentenamer-silica composite is recyclable. As such, the polypentenamer-silica composite can be used for manufacturing recyclable tires.

Abstract: The organic semiconductor polymers relate to polymers containing an indolo-naphthyridine-6,13-dione thiophene (INDT) chromophore. The organic semiconductor polymers are formed by polymerizing INDT monomer with thiophene to obtain a conjugated polymer of the chromophore linked by thiophene monomers (INDT-T), with phenyl to obtain a conjugated polymer of the chromophore linked by phenyl monomers (INDT-P), with selenophene to obtain a conjugated polymer of the chromophore linked by selenophene monomers (INDT-S), or with benzothiadazole to obtain a conjugated polymer of the chromophore linked by benzothiadazole monomers (INDT-BT).
