The surface of magnetite nanoparticle (MNP) was modified with poly(acrylic acid)(PAA)-poly(ethylene glycol) methyl methacrylate (PEGMA) (co)polymer to obtain water dispersible MNP pH sensitive surfaces via atom transfer radical polymerization (ATRP) tert-butyl acrylate (t-BA), followed by the t-BA group deprotection. Molar compositions were systematically varied, namely 100:0, 75:25, 50:50 and ...

This short note describes the synthesis of compound 6,6′-di-(2″-thiophenol)-2,2′-bipyridine from its methyl phenyl sulfane precursor via deprotection groups. The product as well intermediate in synthetic route have been characterized by UV-Vis spectroscopy, 1H- and 13C-NMR FT-IR HR-MS analysis. work presents a rare example tetradentate chelators that bears pyridyl backbones thiophenol donors fo...

A new approach to the synthesis of Z-dehydrotryptophan (ΔTrp) peptides is described. This uses Fmoc-β-HOTrp(Boc)(TBS)-OH as a building block, which readily prepared in high yield and incorporated into using solid-phase Fmoc chemistry. The tert-butyldimethylsilyl-protected indolic alcohol eliminated during global deprotection/resin cleavage give ΔTrp exclusively thermodynamically favored Z isome...

The synthesis of a methanofullerene platform bearing on one side an alkyne and the other protected is reported. This clickable fullerene building block was functionalized by two distinct BODIPY azido derivatives using 1st CuAAC/alkyne deprotection/2nd CuAAC, sequence, through either stepwise or one-pot processes in efficient manner. triad displays strong absorption from 300 to 700 nm. fluoresce...

(Oligo)phenothiazinyl thioacetates, synthesized by a one-pot sequence, are electrochemically oxidizable and highly fluorescent. SAMs can be readily formed from thiols prepared by in situ deprotection of the thioacetates in the presence of a gold-coated silicon wafer. Monolayer formation is confirmed by ellipsometry and the results compared to those obtained by force field and DFT calculations.
