Grafting nitroxide radicals on nanodiamond surface using click chemistry.
We demonstrate grafting of nitroxide radicals on the surface of nanodiamonds (NDs). The surface of NDs is functionalized by azide groups. Nitroxide radicals are covalently bonded using Cu(I)-catalyzed azide/alkyne-click chemistry approach. The reaction is confirmed by infrared spectroscopy. The grafting of nitroxides is also verified by studying the rotational correlational time using electron ...
متن کاملSurface-Supported Hydrocarbon π Radicals Show Kondo Behavior
Stable hydrocarbon radicals are utilized as spin standards and prototype metal-free molecular magnets able to withstand ambient conditions. Our study presents experimental results obtained with submolecular resolution by scanning tunneling microscopy and spectroscopy from monomers and dimers of stable hydrocarbon π radicals adsorbed on the Au(111) surface at 7-50 K. We provide conclusive eviden...
متن کاملThermal and UV Hydrosilylation of Alcohol-Based Bifunctional Alkynes on Si (111) surfaces: How surface radicals influence surface bond formation
Using two different hydrosilylation methods, low temperature thermal and UV initiation, silicon (111) hydrogenated surfaces were functionalized in presence of an OH-terminated alkyne, a CF3-terminated alkyne and a mixed equimolar ratio of the two alkynes. XPS studies revealed that in the absence of premeditated surface radical through low temperature hydrosilylation, the surface grafting procee...
متن کاملOn Radicals of Module Coalgebras
We introduce the notion of idempotent radical class of module coalgebras over a bialgebra B. We prove that if R is an idempotent radical class of B-module coalgebras, then every B-module coalgebra contains a unique maximal B-submodule coalgebra in R. Moreover, a B-module coalgebra C is a member of R if, and only if, DB is in R for every simple subcoalgebra D of C. The collection of B-cocleft co...
متن کامل) radicals
We report on the production of a pulsed molecular beam of metastable NH (a 1∆) radicals and present first results on the Stark deceleration of the NH (a 1∆, J = 2,MΩ = −4) radicals from 550 m/s to 330 m/s. The decelerated molecules are excited on the spin-forbidden A 3Π ← a 1∆ transition, and detected via their subsequent spontaneous fluorescence to the X 3Σ−, v” = 0 ground-state. These experim...
