Mixed Ionic–Electronic Conduction in Binary Polymer Nanoparticle Assemblies

Polymer-based mixed ionic–electronic conductors (MIECs) are desired for both bulk and interfacial materials in next-generation energy storage and electronic devices. Polymer-based MIECs contain two principal components, one for electronic…

Polymer nanostructures through packing of spheres.

This chapter discusses about the polymer nanostructures through packing of spheres. The current protocols for the synthesis of org. nanoparticles and methods of self-assembly of nanoparticles, which may serve as a starting point for researchers…

Time- and Polarization-Resolved Photoluminescence of Individual Semicrystalline Polythiophene (P3HT) Nanoparticles

We report on a remarkable size and internal structure dependence on time- and polarization-resolved photoluminescence (PL) from individual regioregular rrP3HT (poly-3-(hexylthiophine)) nanoparticles. For the smallest particles (similar to 34 nm) with…

In this Perspective, we discuss the possibility of constructing binary nanoparticle superlattices for organic photovoltaic applications and some of the interesting new photophysics emerging from preliminary studies. We summarize recent advances in…

Tuning Aggregation of Poly(3-hexylthiophene) within Nanoparticles

Nanoparticles derived from pi-conjugated polymers have gained widespread attention as active layer materials in various organic electronics applications. The optoelectronic, charge transfer, and charge transport properties of pi-conjugated polymers…

Fabrication conditions for efficient organic photovoltaic cells from aqueous dispersions of nanoparticles

For environmentally friendly and cost-effective manufacturing of organic photovoltaic (OPV) cells, it is highly desirable to replace haloarenes with water as the active layer fabrication solvent. Replacing an organic solvent with water requires…

Analysis of hole transport in thin films and nanoparticle assemblies of poly(3-hexylthiophene)

We report numerical simulation results on hole transport in layers of the organic polymer poly(3-hexylthiophene) (P3HT) of different nanostructures based on a deterministic, phenomenological drift diffusion-reaction model that accounts for hole…

Multiscale Active Layer Morphologies for Organic Photovoltaics Through Self-Assembly of Nanospheres

We address here the need for a general strategy to control molecular assembly over multiple length scales. Efficient organic photovoltaics require an active layer comprised of a mesoscale interconnected networks of nanoscale aggregates of…

Polymer Nanoparticle Assemblies: A Versatile Route to Functional Mesostructures

Fabricating macromolecular mesoscale assemblies containing disparate components with targeted molecular order for each of the components on the nanoscale and targeted assembly of the components in the mesoscale is a challenge. In this Perspective, we…
