Synthesis, characterization, and optical response of dipolar and non-dipolar poly(phenylenevinylene) dendrimers

New dipolar and non-dipolar poly(phenylenevinylene) dendrimers bearing electron-donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta-substitution pattern, large Stokes shifts can be observed when π-donor and π-acceptor groups are connected by a m-phenylenevinylene system.

A Horner-Wadsworth-Emmons approach to dipolar and non-dipolar poly(phenylenevinylene)dendrimers

The synthesis of first generation phenylenevinylene dendrimers is described. The Horner-Wadsworth-Emmons reaction is used for this purpose. The reported methodology permits the preparation of dipolar and non-dipolar structures. A second generation dendron bearing peripheral electron donor groups is also reported.

Mild ruthenium-catalyzed intermolecular alkyne cyclotrimerization

Grubbs' catalyst [(PCy3)2Cl2Ru=CHPh, 7] was shown for the first time to be an effective catalyst for the mild intermolecular cyclotrimerization of terminal alkynes (1-6). The reaction is general and the isomeric trisubstit
