General description
Dendrimers and dendrons are symmetrically branched polymer structures that possess a well-defined spatial distribution of functional groups.[1] Dendrimers are chemically modified by attaching poly ethylene glycol (PEG) molecule to increase its solubility and prolong circulation half-life.[2] “Clickable groups”, such as primary acetylenes, are introduced to the mono dispersed dendritic structures, using “click” chemistry.[1][3]

Click chemistry is an efficient and chemoselective synthetic method for coupling molecular fragments under mild reaction conditions. Since the advent in 2001 of methods to improve stereochemical conservation, the click chemistry approach has been broadly used to construct diverse chemotypes
