Strategies for the Synthesis of Higher Acenes
نویسندگان
چکیده
The outstanding performance of pentacene-based molecules in molecular electronics, as well as the predicted enhanced semiconducting properties of extended acenes, have stimulated the development of new synthetic methods and functionalization strategies for the preparation of stable and soluble acenes larger than tetracene with the aim of obtaining improved functional materials.

The synthesis, crystal structure and charge-transport properties of hexacene.
Acenes can be thought of as one-dimensional strips of graphene and they have the potential to be used in the next generation of electronic devices. However, because acenes larger than pentacene have been found to be unstable, it was generally accepted that they would not be particularly useful materials under normal conditions. Here, we show that, by using a physical vapour-transport method, pl...
متن کاملIndeno[1,2-b]fluorenes: fully conjugated antiaromatic analogues of acenes.
Acenes such as pentacene have been widely studied over the last decade because of their highly promising potential as organic semiconductors, and have found use in devices such as photovoltaics and field-effect transistors. Nonetheless, the locked s-cis diene units within acenes are an Achilles' heal, in that many acenes readily dimerize and react with oxygen. As a possible alternative, we have...
متن کاملSynthesis and structural characterization of crystalline nonacenes.
Acenes and functionalized acenes have played a pivotal role in the development of organic electronic materials. From the first report of high-mobility organic transistors based on vapor-deposited pentacene, to high-efficiency organic lightemitting diodes based on anthracene, and the remarkable transport properties of rubrene, these linearly fused hydrocarbons have made significant contributions...
متن کاملThe larger N-heteroacenes*
The history and development of pyrazineand pyridine-type heteroacenes and their use in solid-state organic electronics are discussed and reviewed. The larger N-heteroacenes are potential electronor hole-transporting materials and should therefore complement acenes in organic electronics. As they feature electronegative nitrogen ring atoms in their molecular skeleton, issues with oxidation shoul...
متن کاملRealist Synthesis of the International Theory and Evidence on Strategies to Improve Childhood Vaccination in Low- and Middle-Income Countries: Developing Strategies for the Nigerian Healthcare System
Background Childhood vaccination coverage rates in low- and middle-income countries (LMICs) vary significantly, with some countries achieving higher rates than others. Several attempts have been made in Nigeria to achieve universal vaccination coverage but with limited success. This study aimed to analyse strategies used to improve ...
