Synthesis and Electronic Properties of Donor−Acceptor π-Conjugated Siloles

An efficient method is presented for the synthesis of novel donor−acceptor silole chromophores through selective monohalogenation of 2,5-dimetallosiloles followed by Negishi alkyne cross-coupling reactions. The electronic properties and crystal packing of these new siloles can be controlled through...

Summary:An efficient method is presented for the synthesis of novel donor−acceptor silole chromophores through selective monohalogenation of 2,5-dimetallosiloles followed by Negishi alkyne cross-coupling reactions. The electronic properties and crystal packing of these new siloles can be controlled through judicious combinations of peripheral functional groups.
