Clusters for alkyne-azide click reactions
Dalton Transactions, 2010The clusters Ti(6)O(4)(OPr)(8)(OOC(CH(2))(2)C[triple bond]CH)(8) and [Zr(6)O(4)(OH)(4)(OOC(CH(2))(3)C[triple bond]CH)(12)](2) with acetylenic carboxylate ligands were prepared and structurally characterized in solution and in the crystalline state. Model reactions showed that they are suitable candidates for the formation of cluster-based inorganic ...

Chemoselective derivatization of a bionanoparticle by click reaction and ATRP reaction
Chemical Communications, 2007Horse spleen apoferritin, the hollow protein shell derived from ferritin, a special biological nanoparticle, can be chemoselectively modified at the lysine residues, which affords a robust scaffold for further chemical reactions including Cu(i)-catalyzed azide-alkyne cycloaddition reaction and atom transfer radical polymerization reaction.

Intramolecular Nitrone Interrupted Click Reaction
Organic LettersWe document the intramolecular interception of a Cu-catalyzed azidoalkyne cycloaddition employing a suitably placed nitrone group, providing a simple route to the unprecedented spiro-polyheterocyclic scaffold. The reaction is comprised of a Cu-catalyzed [3 + 2]-cycloaddition of (2-azidoaryl)isatogen with a terminal alkyne and the intramolecular ...

Radical-mediated click-clip reactions
ScienceClick reactions, which are characterized by rapid, high-yielding, and highly selective coupling of two reaction partners, are powerful tools in synthesis but are rarely reversible. Innovative strategies that reverse such couplings in a precise and on-demand manner, enabling a click-clip sequence, would greatly expand the technique’s versatility. Herein,

Heterovalent Click Reactions on DNA Origami
Bioconjugate ChemistryNucleic acid nanoparticles (NANPs) fabricated by using the DNA origami method have broad utility in materials science and bioengineering. Their site-specific, heterovalent functionalization with secondary molecules such as proteins or fluorophores is a unique feature of this technology that drives its utility.

Core functionalization of polydiacetylene micelles by a “click” reaction
Soft Matter, 2011Diacetylene amphiphile bearing terminal alkyne moiety form micelles which can be further photopolymerized. Herein we address the covalent grafting of a fluorescent label within the micelles by a “click” reaction. Fluorescence experiments revealed that micelles act for the label as a protective shield from the bulk water.

Two-color emissive probes for click reactions
Chem. Commun., 2014CuAAC is visualized using a BODIPY reaction system by the bathochromic shift of the fluorescence wavelength in ensemble and microscopy experiments. Reaction progress is correlated with chromophore elongation fading out disturbing background fluorescence.

Polymer “Clicking” by CuAAC Reactions
Macromolecular Rapid Communications, 2008AbstractThe CuAAC “click” reaction has developed as one of the most useful and widely employed reactions in ligation within polymer chemistry. This is due to the unique properties of the Cu(I) catalysis which renders the reaction quantitative even at low concentrations, orthogonal with other chemistries and extremely robust.
