(α-Man)-containing neoglycoconjugates possessing aliphatic-, aromatic-, and carbohydrate-centered architectures and differing in structural characteristics such as valency, topology, and nature of the linker have been synthesized using click chemistry that shows its value as an efficient and versatile methodology for accessing tailor-made multivalentneoglycoconjugates. The binding behaviour of these

Goldnanoparticle decorated glycodendrimers 1, 2, 3 and 4 were synthesized using a click chemistry approach. Goldnanoparticles (NPs) were synthesized in good yields either by stabilization or encapsulation of the triazolyl glycodendrimers. Goldnanoparticles were stabilized (DSNPs) by the zeroth generation dendrimer and encapsulated (DENPs) by the first generation glycodendrimer. The Au–DSNPs and
Triazole-based novel dendrimers with ferrocenyl surface groups have been achieved through click chemistry, both by divergent and convergent approaches. The presence of more ferrocenyl and triazolyl units in dendrimers 1–4 alters the current potential curve in the voltammogram and also the absorption coefficient in the UV-vis spectrum.
Phenothiazine dendritic architectures with 1,2,3-triazole as a bridgingunit are synthesized through a convergent approach using click chemistry and when used as additives in dye-sensitized solar cells (DSSCs) show increased efficiency in solar energy harvesting systems. The presence of a greater number of phenothiazine and triazoleunits increased the molar absorption coefficient and fluorescence
