A Simplified Approach to N- and N,N′-Linked 1,2,4-Triazoles by Transamination

, 2008
A facile one-step procedure for the preparation of 4,4'-bis-1,2,4-triazole is reported. Direct transamination of N,N-dimethylformamide azine dihydrochloride by heating with 4-amino-1,2,4-triazole in refluxing benzene readily yields the target molecule in

Controlling Aggregation in Highly Emissive Pt(II) Complexes Bearing Tridentate Dianionic N∧N∧N Ligands. Synthesis, Photophysics, and Electroluminescence

, 2011
Neutral Pt(II) complexes bearing tridentate dianionic 2,6-bis(1H-1,2,4-triazol-5-yl)pyridine and ancillary alkyl-substituted pyridine ligands have been synthesized and characterized. They show bright green emission, reaching 73% photoluminescence quantum

Introducing Catalytic Diversity into Single-Site Chabazite Zeolites of Fixed Composition via Synthetic Control of Active Site Proximity

, 2017
We report a synthesis–structure–function relation describing how different routes to crystallize single tetrahedral-site (T-site) zeolites of fixed composition lead to different arrangements of framework Al atoms and, in turn, of extraframework proton ...

Solution of the One‐Dimensional N‐Body Problems with Quadratic and/or Inversely Quadratic Pair Potentials

, 1971
The quantum‐mechanical problems of N 1‐dimensional equal particles of mass m interacting pairwise via quadratic (``harmonical'') and/or inversely quadratic (``centrifugal'') potentials is solved.

New approaches to the analysis of high connectivity materials: design frameworks based upon 4(4)- and 6(3)-subnet tectons.

Accounts of Chemical Research, 2005
Coordination framework polymers derived from lanthanide metal ions with N,N'-dioxide ligands (4,4'-bipyridine-N,N'-dioxide, pyrazine-N,N'-dioxide, 1,2-bis(pyridin-4-yl)ethane-N,N'-dioxide, trans-1,2-bis(pyridin-4-yl)ethene-N,N'-dioxide) exhibit such ...

The Decamethylferrocenium/Decamethylferrocene Redox Couple: A Superior Redox Standard to the Ferrocenium/Ferrocene Redox Couple for Studying Solvent Effects on the Thermodynamics of Electron Transfer

, 1999
The solvent dependence of the formal redox potentials of the ferrocenium/ferrocene (Fc+/0) and 1,2,3,4,5-pentamethylferrocenium/1,2,3,4,5-pentamethylferrocene (Me5Fc+/0) couples versus the decamethylferrocenium/decamethylferrocene (Me10Fc+/0) couple ...

Synthesis and biological evaluation of N-naphthoyl-phenylglyoxamide-based small molecular antimicrobial peptide mimics as novel antimicrobial agents and biofilm inhibitors.

Organic and biomolecular chemistry, 2016
Antimicrobial peptides (AMPs) are a key component of the human immune system. Synthetic AMP mimics represent a novel strategy to counteract the increasing incidence of antimicrobial resistance.

On the Reality of the Eigenvalues for a Class of -Symmetric Oscillators

, 2002
We study the eigenvalue problem with the boundary conditions that decays to zero as z tends to infinity along the rays , where is a real polynomial and . We prove that if for some we have for all , then the eigenvalues are all positive real.

Structure-activity relationships for cytotoxic ruthenium(II) arene complexes containing N,N-, N,O-, and O,O-chelating ligands.

Journal of Medicinal Chemistry, 2006
We report structure-activity relationships for organometallic RuII complexes of the type [(eta6-arene)Ru(XY)Cl]Z, where XY is an N,N- (diamine), N,O- (e.g., amino acidate), or O,O- (e.g., beta-diketonate) chelating ligand, the arene ranges from benzene ...

Information theory and coding

, 1963
(a) Show that for an alphabet of unlimited size, it is possible to create a uniquely decodable prefix code for its letters such that their average codeword length is no more than 2 bits, provided that the alphabet letters obey a certain probability ...
