A structural interpretation of the acidity of groups associated with the hemes of hemoglobin and hemoglobin derivatives [PDF]
, 1940 Since the discovery by Bohr and coworkers in 1904 of the effect of acidity on the oxygen equilibrium of hemoglobin, there have been a large number of investigations directed towards clarification of the physicochemical relationships of acid groups with ...

Crystal structure and thermal behaviour of pyridinium styphnate
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the crystal structure of the title molecular salt, C5H6N+·C6H2N3O8− (systematic name: pyridinium 3-hydroxy-2,4,6-trinitrophenolate), the pyridinium cation and the 3-hydroxy-2,4,6-trinitrophenolate anion are linked through bifurcated N—H...(O,O ...

Zeolite-dye micro lasers [PDF]
, 1998 We present a new class of micro lasers based on nanoporous molecular sieve host-guest systems. Organic dye guest molecules of 1-Ethyl-4-(4-(p-Dimethylaminophenyl)-1,3-butadienyl)-pyridinium Perchlorat were inserted into the 0.73-nm-wide channel pores of ...

In Situ Construction of Imidazopyridinium Fluorescent Labels for Bioconjugation
Angewandte Chemie International Edition, EarlyView.Chromophore engineering of isoquinoline aldehydes generates TICT‐based fluorogenic dyes for in situ labeling of diverse (bio)molecules with large Stokes shifts compatible with cell imaging. ABSTRACT Simple, efficient transformations of fluorogenic nature that proceed under biocompatible conditions without the formation of byproducts are of high ...

Imidazole aldoximes effective in assisting butyrylcholinesterase catalysis of organophosphate detoxification. [PDF]
, 2014 Intoxication by organophosphate (OP) nerve agents and pesticides should be addressed by efficient, quickly deployable countermeasures such as antidotes reactivating acetylcholinesterase or scavenging the parent OP.

Bis(4,4′-bipyridin-1-ium) cis-bis(1,2-dicyano-2-sulfidoethene-1-sulfinato-κ2S,S′)platinate(2−)
IUCrDataCrystals of the sulfinate-containing platinate salt, (C10H9N2)2[Pt(C4N2O2S2)2], were obtained from a solution of [Pt(4,4′-bpy)2(mnt)] after a long period with minimal light (4,4′-bpy is 4,4′-bipyridine and mnt is maleonitriledithiolate). In the crystals,
