Journal ArticleDOI
Discotic liquid crystals: a new generation of organic semiconductors
TL;DR: This critical review covers various aspects of recent research on discotic liquid crystals, in particular, molecular design concepts, supramolecular structure, processing into ordered thin films and fabrication of electronic devices.
Journal ArticleDOI
Thieno[3,2-b]thiophene-Diketopyrrolopyrrole-Containing Polymers for High-Performance Organic Field-Effect Transistors and Organic Photovoltaic Devices

TL;DR: The synthesis and polymerization of a novel thieno[3,2-b]thiophene-diketopyrrolopyrrole-based monomer is reported, which has a maximum hole mobility of 1.95 cm(2) V(-1) s(-1), which is the highest mobility from a polymer-based OFET reported to date.
Journal ArticleDOI

TL;DR: The thermoelectric properties of various poly(3,4-ethylenedioxythiophene) samples are measured, and a marked increase in the Seebeck coefficient is observed when the electrical conductivity is enhanced through molecular organization, which initiates the transition from a Fermi glass to a semi-metal.
Journal ArticleDOI
Charge transport properties in discotic liquid crystals: a quantum-chemical insight into structure-property relationships.
Vincent Lemaur,Demetrio A. da Silva Filho,Veaceslav Coropceanu,Matthias Lehmann,Yves Geerts,Jorge Piris,Michael G. Debije,Anick M van de Craats,Kittusamy Senthilkumar,Laurens D. A. Siebbeles,J. M. Warman,Jean-Luc Brédas,Jérôme Cornil +12 more
TL;DR: A significant increase in the charge mobility when going from triphenylene to hexaazatrinaphthylene is predicted; this finding has been confirmed by measurements carried out with the pulse-radiolysis time-resolved microwave conductivity technique.
Journal ArticleDOI
Electrochemistry, Spectroscopy and Electrogenerated Chemiluminescence of Perylene, Terrylene, and Quaterrylene Diimides in Aprotic Solution
TL;DR: In this article, the electrochemistry, UV−vis spectrophotometry, photoluminescence, and electrogenerated chemilumininescence (ECL) of perylenedicarboxylic imide, perylenetetetracarboxymoxylic diimide (PDI), terrylenetetricarboxylic diimides (TDI), and quaterrylenecarboxynecaroxylinear diimidemide (QDI) were investigated.
