TL;DR: In this article, the triplet state of benzophenone oxidizes Ni((14)aneN/sub 4/sup 2 +/ to a Ni(III) intermediate which subsequently produces the dimer of the complex as a product.
Abstract: The triplet state of benzophenone oxidizes Ni((14)aneN/sub 4//sup 2 +/ to a Ni(III) intermediate which subsequently produces the dimer of the complex as a product. The nature of the product was confirmed by structural studies. (Ni(13-At))/sup +/ reacts with the triplet of fluorenone and /sup 2/Estate of Cr(bpy)/sub 3//sup 3 +/ forming also a dimer in a reaction that involves different intermediates. Intermediates in the photoinduced oxidations of the macrocycles have been investigated by flash photolysis. The mechanism of the photoinduced oxidation is discussed in terms of the reported properties of the macrocycles.

TL;DR: In this article, the electrochemical reductions of fluorenone hydrazone (Fl=NNH2) and benzophenone analogs were studied at platinum cathodes in DMF−0.1 M(n-Bu)4NClO4 in the absence and presence of an added proton donor.

TL;DR: In this paper, a photoconductive layer is produced upon a substrate by coating the substrate with a solution in an organic solvent of a polyamic acid and of 2,4,7-trinitro-9-fluorenone (TNF) and/or 2.4,5,7,tetranitro 9-fluororenone and heating the coated substrate at a temperature not exceeding 150° C.
Abstract: A photoconductive layer is produced upon a substrate by coating the substrate with a solution in an organic solvent of a polyamic acid and of 2,4,7-trinitro-9-fluorenone (TNF) and/or 2,4,5,7-tetranitro-9-fluorenone and heating the coated substrate at a temperature not exceeding 150° C. to form on the substrate a polyimide coating containing the said fluorenone compound as a photosensitizer.
