Visible-light-mediated catalyst-free synthesis of unnatural α-amino acids and peptide macrocycles
Nature Communications, 2021 To address the shortcomings in the application of bioactive peptides as drugs, incorporation of unnatural amino acids (UAAs) has been used. Here, the authors report an ionic compound-promoted C-N cleavage of alkyl pyridinium to generate alkyl radicals ...

Advanced Functional Materials, EarlyView.This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

The alkyl moieties in wax esters and alkyl diacyl glycerols af sharks
Journal of Lipid Research, 1971 The alkyl moieties in wax esters and alkyl diacyl glycerols from the liver of the dogfish, soupfin shark, and silky shark are almost exclusively saturated and monounsaturated, the main alkyl moieties being the C16 and C18 chains in both lipid classes ...

Functionalizing Graphene Oxide with Alkylamine by Gamma-ray Irradiation Method
Nanomaterials, 2017 A gamma-ray irradiation technique was used to functionalize graphene oxide (GO) with alkylamines of various alkyl chain lengths. Functionalization of the alkyl chains onto the GO was confirmed by nuclear magnetic resonance (1H NMR), Fourier transform ...

Oxygen-Induced Dimerization of Alkyl-Manganese(II) 2,6-Bisiminopyridine Complexes: Selective Synthesis of a New Ditopic NNN-Pincer Ligand [PDF]
, 2016 The outcome of the reaction of manganese(II) dialkyls with 2,6-bisiminopyridine (BIP) ligands is dramatically altered by the presence of very small amounts of oxygen (< 0.5 mol %), leading to binuclear species.
