Degradation of chlorinated benzaldehydes in aqueous solutions by UV-irradiation

open access: yesInternational Journal of Photoenergy, 2002
Photoinduced degradation of chlorinated benzaldehydes was investigated using UV light with λ = 253.7 nm in aerated aqueous solutions. Substrate degradation rate as expressed by first order reaction kinetics revealed rate constants, k; 7.45×10−3 min-1, 3 ...

Synthesis and Characterization of Chiral Nitrobenzaldehyde - Schiff Base Ligands

open access: yesMolecules, 2003
Three chiral nitrobenzaldehyde/Schiff base ligands (2a-c) were prepared by the reaction of ortho, meta, and para-NO2 substituted benzaldehydes (1a-c) with (1R,2R)-(-)-1,2-diaminocyclohexane. The structures of ligands 2a-c were characterized by IR, 1H-NMR,

Large acceleration under highly concentrated conditions: Synthesis of chalcones using a small amount of DMF or [emim]N(CN)2

open access: yesResults in Chemistry, 2022
A variety of chalcones were synthesized by the reactions between benzaldehydes and acetophenones catalyzed by Ba(OH)2. The reactions in the presence of a small amount of DMF or 1-ethyl-3-methylimidazolium dicyanamide ([emim]N(CN)2) were faster than those

Benzaldehyde-Functionalized Polymer Vesicles [PDF]

open access: yesACS Nano, 2009
Polymer vesicles with diameters of ca. 100-600 nm and bearing benzaldehyde functionalities within the vesicular walls were constructed through self-assembly of an amphiphilic block copolymer PEO(45)-b-PVBA(26) in water. The reactivity of the benzaldehyde functionalities was verified by cross-linking the polymersomes and also by a one-pot cross-linking ...

1,3-Dipolar cycloadditions of azomethine imines [PDF]

open access: yes, 2015
Azomethine imines are considered 1,3-dipoles of the aza-allyl type which are transient intermediates and should be generated in situ but can also be stable and isolable compounds.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
