Silole-core Dendrimers: A Facile Synthesis and Photophysical Properties

Silole-core dendrimers having benzyl ether-type dendron units, readily synthesized by the Ni-catalyzed reaction of benzyloxy-substituted diphenylacetylenes with 1,1,2,2-tetramethyldisilane, display, upon excitation of the dendron units, efficient energy transfer from the dendron units to the silole...

Description
Summary:Silole-core dendrimers having benzyl ether-type dendron units, readily synthesized by the Ni-catalyzed reaction of benzyloxy-substituted diphenylacetylenes with 1,1,2,2-tetramethyldisilane, display, upon excitation of the dendron units, efficient energy transfer from the dendron units to the silole core, resulting in strong emission from the silole ring.
