Design, synthesis and characterization of new series of first-generation V-shaped dendrimers bearing phenylenevinylene dendritic branches in periphery and pyridine as a core is described. A preliminary study of the optical properties of the resulting compounds was conducted by UV/vis and fluorescence spectroscopy.

A new series of V-shaped pyridine-cored pi-conjugated oligomers are synthesized utilizing two-fold Heck/Suzuki coupling reactions. Optical properties of these compounds (lambda(max)=390-449 nm, phi(eta)=79-5%, in solutions) are discussed. They are shown to be thermally stable and soluble in common organic solvents. Stilbenoid oligomers exhibited much higher fluorescence quantum yields than tri- and tetra-phenylethylene substituted oligomers in solutions. (C) 2012 Elsevier Ltd. All rights reserved.
