The performance of organic semiconductor devices is linked to highly-ordered nanostructures of self-assembled molecules and polymers. We employ many-body perturbation theory and study the excited states in bulk compolymers. We discover that acceptors in the polymer scaffold introduce a, hitherto unrecognized, conduction impurity band. The donor units are surrounded by conjugated bands which are only mildly perturbed by the presence of acceptors. Along the polymer axis, mutual interactions among…

A general relationship between disorder, aggregation and charge transport in conjugated polymers.

TLDR
A unified model of how charge carriers travel in conjugated polymer films is proposed and it is shown that in high-molecular-weight semiconducting polymers the limiting charge transport step is trapping caused by lattice disorder, and that short-range intermolescular aggregation is sufficient for efficient long-range charge transport.

Approaching disorder-free transport in high-mobility conjugated polymers

TLDR
A comparative transport study of several high-mobility conjugated polymers by field-effect-modulated Seebeck, transistor and sub-bandgap optical absorption measurements is reported, showing that in several of these polymers, the charge transport properties approach intrinsic disorder-free limits at which all molecular sites are thermally accessible.

Two-dimensional charge transport in self-organized, high-mobility conjugated polymers

Self-organization in many solution-processed, semiconducting conjugated polymers results in complex microstructures, in which ordered microcrystalline domains are embedded in an amorphous matrix.

Narrow Band Gap Conjugated Polyelectrolytes.

TLDR
That no doping is observed with cationic NBGCPEs indicates that the interplay between electrostatic forces and the redox chemistry of the organic semiconducting chain is essential for stabilizing the polaronic states and increasing the conductivity of the bulk.

General strategy for self-assembly of highly oriented nanocrystalline semiconducting polymers with high mobility.

TLDR
A sandwich tunnel system separated by functionalized glass spacers is designed to induce capillary action for controlling the polymer nanostructure, crystallinity, and charge transport and creates a promising pathway toward high performance, solution processable, and low-cost organic electronics.

TLDR
Evidence that interchain electronic species do form in conjugated polymer films is reviewed and their number and chemical nature depend on processing conditions; the chain conformation, degree of interchain contact, and rate of energy transfer can be controlled by factors such as choice of solvent, polymer concentration, thermal annealing, presence of electrically charged side groups, and encapsulation of the polymer chains in mesoporous silica.

Molecular origin of high field-effect mobility in an indacenodithiophene-benzothiadiazole copolymer.

TLDR
It is argued that charge transport in high-mobility semiconducting polymers is quasi one-dimensional, that is, predominantly occurring along the backbone, and requires only occasional intermolecular hopping through short π-stacking bridges.

Spontaneous Charge Carrier Localization in Extended One-Dimensional Systems.

TLDR
It is shown for the first time by means of first-principles computations that charge carriers can spontaneously localize due to a purely electronic effect in otherwise perfectly ordered structures.
