We study the effects of molecular structure on the electronic transport and mechanical stability of single-molecule junctions formed with Au point contacts. Two types of linear conjugated molecular wires are compared: those functionalized with methylsulfi

A novel and facile method for direct CC acetylenic bond formation from the C=C double bond by treatment with potassium t-butoxide (t-BuOK) in N,N-dimethylformamide in the air has been found in a 9,10-bis(4-substituted styryl)anthracene series, in 4-substituted 4'-nitrostilbene series, and in 1-(p-nitrophenyl)-4-(p-substituted phenyl)-1,3-butadiene series; its scope and limitations have been examined.The ESR spectrum of the reaction against 4-diethylamino-4'-nitrostilbene was measured to identify an anion radical specied expected for explanation of the mechanism of the dehydrogention reaction.Further, cyclic voltammetric measurements of a series of stilbenes and diphenylacetylenes were carried out in connection with the abovw mechanism.In many cases, interestingly, the use of a large excess of t-BuOH brought about succeeding hydroxylation into the ortho-position of a nitro group on the benzene nucleus.The simple hydroxylation is useful for the synthesis of substituted 5-(arylethynyl)-2-nitrophenols, which are expected to function as non-linear optical materials with the corresponding non-hydroxy compounds.The ultraviolet-visible and fluorescence spectral properties were measured and discussed also with those of the related compounds.
Models for intramolecular exchange in organic π-conjugated open-shell systems. A comparison of 1,1-ethenediyl and carbonyl linked bis(arylnitrenes)

Linkage of two phenylnitrene electron-spin-bearing units by exchange coupling linker groups leads to model open-shell π-conjugated systems of the general structure :N-Ph-X-Ph-N: of various possible connectivity types. Use of variable-temperature electron
