New Macromolecular Research Data Have Been Reported by Investigators at Soochow University (Sequential "Click" Synthesis of "Nano-Diamond-Ring-like" Giant Surfactants Based on Functionalized Hydrophilic POSS/C-60 Tethered with Cyclic

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Macromolecular Research have been published. According to news reporting out of Suzhou, People's Republic of China, by NewsRx editors, research stated, "This paper reports the design and facile synthesis of a novel series of 'nano-diamond-ring-like' giant surfactants composed of a functionalized hydrophilic polyhedral oligomeric silsesquioxane (such as dihydroxyl-functionalized DPOSS) or fullerene (such as carboxylic acid-functionalized AC(60)) head as the 'diamond' and a hydrophobic, cyclic polystyrene (CPS) tail as the 'ring'. The synthetic route combines several steps of 'click-type' reactions, demonstrating highly efficient and modular features."

Our news journalists obtained a quote from the research from Soochow University, "Starting from a specifically designed initiator, trifunctional linear polystyrene (LPS) precursors bearing vinyl, bromo, and alkyne groups were prepared by atom transfer radical polymerization (ATRP). Upon the subsequent azidation of LPS, copper-catalyzed Huisgen [3 + 2] cycloaddition reaction was employed to afford vinyl-functionalized CPS ring in high yield and purity. The vinyl group was then subjected to the thiol-ene reaction to introduce an azide group onto the CPS, providing an azide-functionalized CPS (CPS-N-3) as a 'clickable' cyclic building block to construct giant molecules. Various 'nano-diamond-ring-like' giant surfactants decorating with different 'diamonds', such as hydrophilic DPOSS or AC(60) molecular nanoparticles, can be readily synthesized via the modular sequential 'click' approaches based on this CPS-N-3 building block."

According to the news editors, the research concluded: "These giant surfactants with structural precision represent a novel member in the MNP-based giant surfactant family which might have distinct self-assembly behaviors compared to their linear analogues."
