{rac-5-[Meth-oxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II)
(2011)The title compound, [Ni(C40H28N4O)], was obtained from a Grignard reaction of the respective formyl-porphyrin to yield {5-[hy-droxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II), followed by crystallization from ... -
Radical-mediated thiol–ene ‘click’ reactions in deep eutectic solvents for bioconjugation
(2022)Herein, we report the first application of deep eutectic solvents (DESs) in radical-mediated hydrothiolation reactions. Under UV and atmospheric-oxygen mediated conditions, the thiol–ene reac tion was applied to amino ... -
Raman modes of index-identified freestanding single-walled carbon nanotubes
(2005)Using electron diffraction on freestanding single-walled carbon nanotubes, we have determined the structural indices (n,m) of tubes in the diameter range from 1.4 to 3 nm. On the same freestanding tubes, we have recorded ... -
Rapid and Large-Area Visualization of Grain Boundaries in MoS 2 on SiO 2 Using Vapor Hydrofluoric Acid
(2020)Grain boundaries in two-dimensional (2D) material layers have an impact on their electrical, optoelectronic, and mechanical properties. Therefore, the availability of simple large-area characterization approaches that can ... -
Rapid Iron(III)¿Fluoride¿Mediated Hydrogen Atom Transfer
(2021)We anticipate high-valent metal-fluoride species will be highly effective hydrogen atom transfer (HAT) oxidants because of the magnitude of the H-F bond (in the product) that drives HAT oxidation. We prepared a dimeric ... -
Reaction of porphyrin-based surface-anchored metal?organic frameworks caused by prolonged illumination
(2018)Crystalline surface-anchored metal–organic framework (SURMOF) thin films made from porphyrin-based organic linkers have recently been used in both photon upconversion and photovoltaic applications. While these studies ... -
Reactions of 2-Oxo-2H-1-benzopyran-3-carbonitrile
(1998)Synthetic reactions of2-oxo-2H -1-benzopyran-3-carbonitrile afford productswhich establish that partial or complete cleavage of the startingmaterial occurs in the course of reaction. -
The reactivity of diazabutadienes towards low oxidation state group 13 iodides and the synthesis of a new gallium(I) carbene analogue
(2002)The reactions of two diazabutadiene ligands, Ar-DAB [(ArN[double bond, length as m-dash]CH)2 , Ar = 2,6-Pri2C6H3] and But-DAB [(ButN[double bond, length as m-dash]CH)2] with either GaI or an AlI3/Al mixture have afforded ... -
The reactivity of Gallium-(I), -(II) and -(III) heterocycles towards group 15 substrates: Attempts to prepare gallium-terminal pnictinidene complexes.
(2006)The reactivity of a series of Ga(I), Ga(II) and Ga(III) heterocyclic compounds towards a number of Group 15 substrates has been investigated with a view to prepare examples of gallium–terminal pnictinidene complexes. ... -
Reactivity Properties of Mixed- and High-Valent Bis(μ-Hydroxide)-Dinickel Complexes
(2021)Despite their potential role in enzymatic systems, there is a dearth of hydroxide-bridged high-valent oxidants. We recently reported the synthesis and characterization of NiIINiIII(μ-OH)2 (2) and Ni2 III(μ-OH)2 (3) species ... -
Real-world natural passivation phenomena can limit microplastic generation in water
(2022)Previous studies using Deionized (DI) water found that household plastic products used in food preparation and storage are a local and immediate source of extremely high quantities of microplastics (MPs) released ... -
Recent advances in the development of 1,8-naphthalimide based DNA targeting binders, anticancer and fluorescent cellular imaging agents.
(2013)The development of functional 1,8-naphthalimide derivatives as DNA targeting, anticancer and cellular imaging agents is a fast growing area and has resulted in several such derivatives entering into clinical trials. This ... -
Recent advances in the development of synthetic chemical probes for glycosidase enzymes
(2015)The emergence of synthetic glycoconjugates as chemical probes for the detection of glycosidase enzymes has resulted in the development of a range of useful chemical tools with applications in glycobiology, biotechnology, ... -
The Red Color of Life Transformed – Synthetic Advances and Emerging Applications of Protoporphyrin IX in Chemical Biology
(2020)Protoporphyrin IX (PPIX) is the porphyrin scaffold of heme b, a ubiquitous prosthetic group of proteins responsible for oxygen binding (hemoglobin, myoglobin), electron transfer (cytochrome c) and catalysis (cytochrome ...
