Synthesis and Characterization of Dendronized Polymers

Abstract

This research aims at the synthesis of several dendrons with different functional groups on their surface, and their use as functionalizing agents of synthetic polymers. Two principal products were synthesized and characterized: dendronized MDI oligomers and dendronized PMMI. The results of the characterization studies of dendronized polymers demonstrated the influence of the polarity of dendrons and the dendronization pathway on the properties of the final products.

Synthesis of Organic/Inorganic Hybrid Quatrefoil-Shaped Star-Cyclic Polymer Containing a Polyhedral Oligomeric Silsesquioxane Core

“…Nuclear Magnetic Resonance (NMR) Spectroscopy. All 1 H, 13 C, and 29 Si NMR spectra were recorded on a Bruker AV300 NMR spectrometer operated in the Fourier transform mode. CDCl 3 was used as the solvent.…”

“…The synthesis of polymers with varying chain topologies has always been the focus of polymer chemistry field due to that chain architectures play an important role in determining macromolecular properties and functions in bulk and solution states. − In the past decade, a variety of polymers with intriguing topologies, such as cyclic, − linear-cyclic, , linear-dendritic, , dendronized, − Y-shaped, , H-shaped, − ABC miktoarm star, − hyperbranched, − and dendritic polymers − have been prepared, partially due to the boom of controlled radical polymerization techniques and new concepts (click reaction, Diels−Alder reaction) “borrowed” from modern organic chemistry.…”

Electrochemical Study of a Dendritic Family at the Water/1,2-Dichloroethane Interface

“…In summary, dendritic building blocks are extensively used as nanoscopic auxiliaries for construction of dendronized polymers, [15][16][17][18] self-assembly, [19][20][21] and macromonomers 22,23 or for dendronization of other materials 24,25 or surfaces. 26,27 In previous works 28,29 we reported the synthesis and chemical characterization of a family of dendrons as shown in Figure 1. Construction of these molecules, which bear different numbers and kinds of functional groups on their surface, was based on a synthetic strategy to achieve a dendritic effect on the properties of the resulting building block and the subsequently constructed product.…”

Synthesis of amphiphilic dendrons and their interactions in aqueous solutions with cetyltrimethylammonium p-toluenesulfonate (CTAT)

“…To this aim, a variety of molecular building blocks have already been combined. Recently, dendrimers and their segments, dendrons, have fostered scientific interest as a class of molecular building blocks in the construction of supramolecular systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”
