title: Synthesis of novel cross-conjugated dendritic fluorophores containing both phenylenevinylene and phenyleneethynylene moieties.
abstract: New dendrons and dendrimers with dendritic arms composed of alternate phenyleneethynylene and phenylenevinylene moieties have been efficiently synthesized using orthogonal and convergent syntheses that combine Sonogashira and Horner-Wadsworth-Emmons reactions. Two different iterative routes have been developed that allow specific control over the placement of double and triple bonds within the interior of the dendrimers. A preliminary study of the UV and photoluminescence (PL) properties of the resulting compounds is also described. All of the examples prepared are blue-luminescent.
