Synthesis, photophysical and electrochemical properties and DSSC applications of triphenylamine chalcone dendrimers via click chemistry

Fluorene-cored dendrimers containing a triphenylamine chalcone unit at the periphery have been synthesized by click chemistry approach, and their photophysical and electrochemical properties have been investigated.

The Rise of Azide–Alkyne 1,3-Dipolar 'Click' Cycloaddition and its Application to Polymer Science and Surface Modification

New methods to synthesize and functionalize polymers are of constant interest to the polymer scientist. The 1,3-dipolar cycloaddition between an azide and terminal alkyne has received much attention since the reports that copper(i) provides high yields and regioselective synthesis of 1,4-substituted 1,2,3-triazoles. This coupling chemistry has been rapidly adopted by polymer scientists in the synthesis and post-polymerization modification of polymers. This Review will provide the historical context of the recent development of the copper-mediated azide–alkyne cycloaddition and its use in polymer science, particularly in dendrimer synthesis/functionalization, surface immobilization/modification, orthogonally functionalizing polymers, and its integration with ATRP (atom transfer radical polymerization).

Facile Approach for Diblock Codendrimers by Fusion between Fréchet Dendrons and PAMAM Dendrons

For the first time, a simple and facile approach for the synthesis of diblock codendrimers by fusion between the azide focal point functionalized Fréchet-type polyether and the propargyl focal point functionalized Tomalia-type PAMAM dendrons has been described based on click chemistry, i.e., the copper-catalyzed cycloaddition reaction between alkyne and azide.
