Journal ArticleDOI

Enhancing the n-Type Conductivity and Thermoelectric Performance of Donor–Acceptor Copolymers through Donor Engineering

TL;DR: The results demonstrate that proper donor engineering can enhance the n-doping efficiency, electrical conductivity, and thermoelectric performance of D-A copolymers.
Journal ArticleDOI

Unraveling the Solution-State Supramolecular Structures of Donor-Acceptor Polymers and their Influence on Solid-State Morphology and Charge-Transport Properties.

TL;DR: It is shown that the solution-state structures of the BDOPV-based conjugated polymer can be tuned such that it forms a 1D rod-like structure in good solvent and a 2D lamellar structure in poor solvent.
Journal ArticleDOI

Transition metal-catalysed molecular n-doping of organic semiconductors

TL;DR: In this article, a general concept of catalysed n-doping of organic semiconductors using air-stable precursor-type molecular dopants is presented, where the incorporation of a transition metal (for example, Pt, Au, Pd) as vapour-deposited nanoparticles or solution-processable organometallic complexes, as assessed by experimental and theoretical evidence, enables greatly increased η in a much shorter doping time and high electrical conductivities.
Journal ArticleDOI

A thermally activated and highly miscible dopant for n-type organic thermoelectrics.

TL;DR: A computer-assisted screening approach is used to rationally design a triaminomethane-type dopant, which exhibit extremely high stability and strong hydride donating property due to its thermally activated doping mechanism and shows excellent counterion-semiconductor miscibility, high doping efficiency and uniformity.
