On March 1, 2011, Kucuk, Asuman C.; Matsui, Jun; Miyashita, Tokuji published an article.Recommanded Product: 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was Langmuir-Blodgett films composed of amphiphilic double-decker shaped polyhedral oligomeric silsesquioxanes. And the article contained the following:
New amphiphilic polyhedral oligomeric silsesquioxanes (POSSs) were synthesized, and their monolayer behavior on a water surface and Langmuir-Blodgett (LB) film formation were studied. Two kinds of amphiphilic POSS mols., which have two or four di(ethylene glycol) units (2OH-DDSQ and 4OH-DDSQ, resp.), were synthesized by direct hydrosilylation of di(ethylene glycol) vinyl ether with double-decker shaped polyhedral oligomeric silsesquioxanes (DDSQs). Surface pressure (π)-area (A) isotherms and Brewster angle microscope (BAM) measurements indicated that both amphiphilic DDSQs form a stable monolayer at the air-water interface. 4OH-DDSQ can be deposited on a solid substrate by the LB technique. Atomic force microscope (AFM) images of a 1-layer 4OH-DDSQ film showed a homogeneous uniform surface on a hydrophilic silicon substrate, whereas nanometer scale dots were formed on a hydrophobic silicon substrate. Multilayer deposition on a hydrophobic substrate resulted in an increase of dot size with increasing deposition number of layers. Also, homogeneous multilayer films with a few voids were obtained on a hydrophilic substrate. 4OH-DDSQ is a good candidate for preparing hybrid nanoassemblies. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Recommanded Product: 2-(2-(Vinyloxy)ethoxy)ethanol
