End-capped, conjugated (dimethylamino)naphthyl nanostructures with alternating (1-naphthylethynyl-p-phenylethynyl)x branches on a 1,3,5-substituted benzene core

Alternating (1-naphthylethynyl-p-phenylethynyl)x 1,3,5-trisubstituted benzene dendrons were efficiently synthesised by the heterocoupling reaction between (1-naphthylethynyl-p-phenyl) xacetylene (x = 1) and 1,3,5-triiodobenzene in the presence of a palladium-copper catalyst system. A longer terminal acetylene chain (x = 2) was obtained from the heterocoupling between 1,3,5-tri(1-ethynyl-5-naphthylethynyl)- benzene and the appropriate iodoaryl derivative. The alternating chains, and their dendron structures, show fluorescence emission, with similar wavelengths and quantum yields. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005.
