The use of 1,3-dipolar cycloaddition reactions between azides and alkynes (click chemistry) has been extremely successful as a versatile synthetic tool to construct novel polymeric systems.[1] Whereas the main thrust has been focused on building up highly elaborate polymeric architectures, such as block copolymers, star polymers, dendrimers, and hyperbranched polymers, it is also noted that the physical properties of such poly(triazole)-based materials are little studied.[1c]Additionally, although there are many examples of the synthesis of dendrimers using click chemistry, only a few concern the preparation of dendronized polymers.[2] These are polymers incorporating multiple dendron segments stemming from a linear polymer backbone and are commonly prepared by graft-to, graft-from, or macromonomer polymerization approaches.[3] The major challenges for these approaches are the difficulty in ensuring complete dendron coverage in the graft-to and graft-from strategies, and the sometimes poor polymerization efficiency in the macromonomer strategy. To improve the synthetic efficacy, it is necessary to make use of reactions that offer perfect conversion efficiency (such as click chemistry). Herein we wish to report a) the successful click synthesis of two different series of dendronized polymers (DPs), AmDP1-AmDP3 and EsDP1-EsDP3, from heterobifunctional amide-linked macromonomers (AmM1-AmM3) and ester-linked macromonomers (EsM1--EsM3), respectively, b) the novel and unique organogelation property of one such poly(triazole)-based dendronized polymer AmDP2, c) the remarkable functionalgroup synergistic effect on polymer interchain H-bonding, owing to the placing of many amide functionalities in close proximity along the polymer chain, and most importantly d) that the macromolecular interactions among the dendronized polymer chains are strongly influenced by the size of dendritic appendages and the nature of the linker functionality. To our knowledge, synthesis of dendronized polymers by AB-type macromonomer polymerization has not been reported before. Moreover, although physical organogels based on dendrimers [4] and linear polymers [5] are known, those based on click poly(triazole) polymers [6] and dendronized polymers [7] are extremely rare.The click macromonomer polymerization is basically a step-growth polymerization. Therefore, to achieve a higher degree of polymerization (DP), it must be ensured that the AB-hetero-bifunctional monomers AmM1-AmM3 are of perfect purity and structural homogeneity. For this purpose, we made use of the symmetrical aliphatic hydrocarbon-based Meldrums acids 1-3[8] as our starting materials. Simple functional-group transformations then led to the target amide-linked macromonomers AmM1-AmM3 in good yields and high purities (see Supporting Information). The macromonomers AmM1-AmM3 were then polymerized in the presence of sodium ascorbate and CuSO 4 in a 1:1:1 solvent mixture of THF, DMF, and water at 25 8C for 4 days. To counteract the poor solubility of the products, DMF was added to m...
