Abstract

. π-Conjugated molecules with fused rings for organic field-effect transistors: design, synthesis and applications. Chemical Society Reviews, 39(5), pp. 1489-1502. doi: 10.1039/b813123f This is the accepted version of the paper.This version of the publication may differ from the final published version. π-Conjugated molecular materials with fused rings are the focus of considerable interest in the emerging area of organic electronics, since the combination of excellent charge carrier mobility and high stability may lead to their practical applications. This tutorial review discusses the synthesis, properties and applications of π-conjugated organic semiconducting materials especially those with fused rings. The achievements to date, the remaining problems and challenges, and the key research that needs to be done in the near future are all discussed. Permanent Snappy text:The synthesis, properties and applications of π-conjugated organic semiconductors especially those with fused rings are discussed in this tutorial review.

First‐Principles Investigation of the Electronic and Conducting Properties of Oligothienoacenes and their Derivatives

“…[1][2][3] However, oligothiophenes can easily deviate from planarity through torsion about the inter-ring single bonds as the conjugated chain length is elongated, which decreases the electron delocalization along the conjugated carbon backbone. Oligoacenes, with their more-rigid and planar structures, suffer from the disadvantages of oxidative instability and extreme insolubility.…”

Crystal structure of 6-cyclohexyl-5H-[1,3]dithiolo[4,5-f]isoindole-2,5,7- (6H)-trione, C15H13NO3S2

“…The title compound was an important intermediate in the preparation of tetrathiafulvalenes derivatives. The title compound, the title crystal structure is only built up by the C 15 H 13 NO 3 The phenyl ring and five-ring group planes (S1-C11-S2-C12-C10, C7-N1-C15-C14-C8) are almost planar, with maximum dihedral angles 1.8°(3) and 2.7°(3), respectively. The torsion angles of C7-N1-C6-C1, N1-C7-C8-C14, C11-S1-C10-C9 and C10-S1-C11-O3 are -121.6(3)°, 0.5(3)°, -175.7(2)°and 176.6(3)°, respectively.…”

“…The advances in the electronic performance of organic devices in the past few years have attracted a great interest not only from the academic world but also from large international companies [2,3]. Tetrathiafulvalenes (TTF) derivatives have gone beyond the field of organic conductors and superconductors, and have been used as building blocks for molecular machines, supramolecular assemblies, electrochemical sensors, OFETs, and solar cells [4,5].…”

Synthesis of Two Novels-Shaped Dibenzo[c,l] Chrysene Derivatives, Crystal Structure, and the Evaluation of their Photophysical Properties

“…Over the past decade significant research has been done and the search for the new π-conjugated systems has been ongoing because of the important, rapidly growing number of applications in electronic devices such as semiconducting materials [2][3][4][5], organic solar cells [6], sensors [7], organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and flexible displays. π-conjugated materials have been extensively studied for their optoelectronic properties due to the offering of low-cost, large-area, and flexible electronic devices [8][9][10].…”
