Nanoscale morphology, dimensional control, and electrical properties of oligoanilines

While nanostructures of organic conductors have generated great interest in recent years, their nanoscale size and shape control remains a significant challenge. Here, we report a general method for producing a variety of oligoaniline nanostructures with well-defined morphologies and dimensionalities. 1-D nanowires, 2-D nanoribbons, and 3-D rectangular nanoplates and nanoflowers of tetraaniline are produced by a solvent exchange process in which the dopant acid can be used to tune the oligomer morphology. The process appears to be a general route for producing nanostructures for a variety of other aniline oligomers such as the phenyl-capped tetramer. X-ray diffraction of the tetraniline nanostructures reveals that they possess different packing arrangements, which results in different nanoscale morphologies with different electrical properties for the structures. The conductivity of a single tetraaniline nanostructure is up to 2 orders of magnitude higher than the highest previously reported value and rivals that of pressed pellets of conventional polyaniline doped with acid. Furthermore, these oligomer nanostructures can be easily processed by a number of methods in order to create thin films composed of aligned nanostructures over a macroscopic area.

Delineating poly(aniline) redox chemistry by using tailored oligo(aryleneamine)s: Towards oligo(aniline)-based organic semiconductors with tunable optoelectronic properties

The simple and elegant Buchwald-Hartwig cross-coupling reaction has been used to synthesise a designed range of new aniline-based tetramers in one step, and without the need for protecting groups. Variation of the central aromatic ring has provided the opportunity to carefully tune the optoelectronic properties in this series, thus enabling a structure-activity relationship study by using a range of photophysical and electrochemical techniques. As a result, the long-proposed sequences of electron-electron (EE) and electron-chemical (EC) processes that support the complex redox and proton-transfer reactions involved in the well-known switching of redox states of poly- and oligo(aniline)s are revealed here for the first time. We also present the initial results from time-dependent DFT calculations to clarify the optoelectronic behaviour of these oligomers. The dc-conductivity measurements of conducting thin films of this series, doped with the prototypical poly(aniline) protonating agent d,l-camphor-10-sulfonic acid (CSA), externally plasticised with triphenyl phosphate (TPP), and processed from m-cresol (MC) solutions, are also presented. Aniline black, blue, orange and red! The Buchwald-Hartwig cross-coupling reaction is used to synthesise a range of new aniline-based tetramers with carefully tunable optoelectronic properties (see figure; EB=emeraldine base; PANI=poly(aniline)). The long-proposed sequences of electron-electron and electron-chemical processes that support the complex redox and proton-transfer reactions involved in the switching of redox states of poly- and oligo(aniline)s are revealed for the first time.

Preparation of Linear Oligoaniline Derivatives Using Titanium Alkoxide as a Condensing Agent

Linear oligoaniline derivatives were prepared by the reaction of aromatic amines and phenols using various titanium alkoxides as condensing agents. The oligomers obtained were silver white microscopic crystals. Titanium alkoxides used were titanium alkoxide or titanium alkoxide aryloxide and the latter showed high dehydration condensation activity in comparison with the usual titanium alkoxides.
