DNA-assisted photoinduced charge transfer between a cationic poly(phenylene vinylene) and a cationic fullerene.
Water-soluble cationic conjugated poly(phenylene vinylene) (PPV) and cationic fullerene were complexed with negatively charged single stranded DNA and double stranded DNA via electrostatic interactions to achieve photoinduced charge transfer with efficiencies as high as those observed from oppositely charged, cationic PPV and anionic fullerene but with distinctly different quenching mechanisms.
متن کاملQuantum-Chemical Insights into the Self-Assembly of Carbon-Based Supramolecular Complexes.
Understanding how molecular systems self-assemble to form well-organized superstructures governed by noncovalent interactions is essential in the field of supramolecular chemistry. In the nanoscience context, the self-assembly of different carbon-based nanoforms (fullerenes, carbon nanotubes and graphene) with, in general, electron-donor molecular systems, has received increasing attention as a...
متن کاملSupramolecular assembly of graphene with functionalized poly(fluorene-alt-phenylene): the role of the anthraquinone pendant groups.
Hybrid materials composed of graphene and conjugated poly(fluorene-alt-phenylene) endowed with redox-active anthraquinone moieties are prepared. Remarkable changes in the electronic properties of the polymer are observed. Effective interactions among the pendant anthraquinone and graphene, likely due to π-π stacking, are confirmed.
متن کاملSolubilization and Encapsulation of Fullerenes by Amphiphilic Block Copolymers
Solubilization and encapsulation of fullerenes C60 and C70 by ultralarge hollow micelles formed by rod-coil diblock copolymers and characterization of the resulting self-organized fullerene-block copolymer assemblies are reported. The solubilization capacity of each fullerene in poly(phenylquinoline)-blockpolystyrene (PPQ-PS) micelles in binary solvents, trifluoroacetic acid/dichloromethane, an...
متن کاملProbing a conjugated polymer's transfer of organization-dependent properties from solutions to films.
The dynamic transfer of a conjugated polymer's organization-dependent properties from the solution state to the solid film state was probed by circularly polarized luminescence (CPL) and circular dichroism (CD) spectroscopy. Different supramolecular organizations within films and aggregate solutions of a chiral poly(p-phenylenevinylene) derivative led to opposite CPL and CD spectra. These drama...
