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.

discovery. Reactions that directly transform inexpensive chemical feedstocks into versatile carbon electrophiles would therefore be highly enabling. Herein, we report the catalytic, regioselective oxidative cyanation of conjugated and nonconjugated alkenes using a homogeneous copper catalyst and a bystanding N-F oxidant to furnish branched alkenyl nitriles that are difficult to prepare using existing methods
