An aromatic amine compound capable of satisfactorily forming a cured product having exceptional alkali resistance by reaction with an epoxy compound; a curing agent for an epoxy compound, the curing agent including the aromatic amine compound; a curable composition including the curing agent for an epoxy compound; a cured product of the curable composition; a method for producing the cured product; and a method for producing the abovementioned aromatic amine compound. The aromatic amine compound has a structure such that a specific position in a central skeleton comprising a fused ring such as a fluorene ring is substituted with a side-chain group including two aromatic groups linked by a flexible bond such as an amide bond, at least one amino group is bonded to the end of the side-chain group, and the structure has no hydroxyl groups.

However, examples of using other oxidants in the presence of copper compounds are rather rare. 2 Polyhaloalkanes (most often, carbon tetrachloride) can act as such oxidants. 3-8 We found a novel redox reaction of double carboncarbon bond formation catalyzed by copper salts, which permits the preparat ion of 2,2-dichlorostyrenes from N-unsubstituted hydrazones of aromatic aldehydes.

The invention relates to a light harvesting array or dye comprising an acceptor linked to a donor, wherein at least one of the acceptor or the donor is an oligomeric unit comprising a first optionally substituted rylene linked via a linker group to a second optionally substituted rylene, the first optionally substituted rylene is linked to the acceptor or the donor and the second optionally substituted rylene is capable of energy transfer to at least one of the first optionally substituted rylene, the acceptor or the donor. The invention also relates to compounds which may be used as light harvesting arrays, methods for their manufacture, and devices and materials comprising the light harvesting array or dye, for example, chromophoric materials, light guides, photobioreactors, photoluminescent algae systems, photodetectors, photovoltaic devices and luminescent/fluorescent solar concentrators.
The present invention relates to a process for preparing dithioesters in which a dithiocarboxylic acid and/or a dithiocarboxylic salt is reacted with a vinyl compound and/or an alkyl compound which includes a leaving group, the reaction being carried out in a biphasic system in which one of the phases comprises water and the weight ratio of the aqueous phase to the organic phase lies in the range from 95:5 to 5:95.
