The synthesis of novel bis(3-carbazoly1)methane linked bis-benzimidazoles is described. Construction symmetrical on the bis-carbazolylmethane scaffold was succeeded by condensation reaction benzene-1,2-diamine derivatives with bis(9-ethyl-9H-carbazole-3-carbaldehyde). structural analysis targeted compounds 4-7 were confirmed NMR, FT-IR spectroscopy and mass spectrometry. thermal stability final...

in this paper, two double helical dinuclear copper(ii) complexes of bis-n,o-bidentate schiff base ligands bis(3-methoxy-n-salicylidene-4,4'-diaminodiphenyl)sulfone (l1) and bis(5-bromo-n-salicylidene-4,4'-diaminodiphenyl)sulfone (l2) were prepared and characterized by elemental analyses (chn), as well as thermal analysis. elemental analyses (chn) suggested that the reaction between ligands and ...

A series of bis-BODIPYs 1-6 bridged via thiophene, furan, N-alkylcarbazole, triphenyl-amine, para- and meta-phenylene groups have been synthesized and characterized by various spectroscopic techniques. The change in the spectroscopic properties of bis-BODIPYs upon varying the size of spacers was studied. X-ray crystal structures of three bis-BODIPYs containing triphenylamine, para- and meta-phe...

The behavioral inhibition system (BIS) and behavioral approach system (BAS) are thought to influence sensitivity to reinforcement and punishment, making them useful for predicting mood-related drinking outcomes. This study provided the first examination of BIS and BAS as moderators of longitudinal within-person associations between mood and alcohol-related consequences in college student drinke...

Reaction of nitrobenzyl alcohol with glucose (200 mol%) in the presence NaOH water-ethanol medium gave 1,2-bis(4-(hydroxymethyl)phenyl)diazene oxide, 1,2-bis(2-(hydroxymethyl)phenyl)diazene oxide and 1,2-bis(4-(1-hydroxyethyl)phenyl)diazene 76%, 76% 72% yields, respectively.

Bis-spiropryran molecules were grafted onto the surface of upconverting nanoparticles. Fluorescence resonance energy transfer from the upconverting nanoparticles to the surface bis-spiropyran molecules triggered the transformation of the ring-closed bis-spiropyran to the ring-open bis-merocyanine forms.

(E,E)-1,4-bis(4'-aminostyryl)-2,5-bis(octyloxy)-benzene (6) and its derivative (E,E)-1,4-bis(4'-acetamidostyryl)-2,5-bis(octyloxy)-benzene (7) were synthesized and characterized after alkylation, bromomethylation, Horner-Emmons reaction and reduction from hydroquinone. In order to gain more molecular electronic data, HOMO and LUMO of compound 6 have been calculated by Gaussian 03 W.

2,2-Bis[4-(2-methacryloxyethoxy)phenyl] propane (bisEMA; CAS 24448-20-2) is an epoxy methacrylate that was developed as a substitute for another epoxy methacrylate, 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy) phenyl]propane (bis-GMA; CAS 1565-94-2), used in dental composite resins. In the 2012 Finnish Product Register of Chemicals, bis-EMA appears in some anaerobic glues and in one gelcoat. Som...

BACKGROUND Explicit recall (ER) is evident in approximately 0.2% of patients given general anaesthesia including muscle relaxants. This prospective study was performed to evaluate if cerebral monitoring using BIS to guide the conduction of anaesthesia could reduce this incidence significantly. PATIENTS AND METHODS A prospective cohort of 4945 consecutive surgical patients requiring muscle rel...
