1H NMR determination of the self-association of an acridine homodimer and its complexation with ethidium bromide in aqueous solution [PDF]

, 2006
1H NMR spectroscopy (500MHz) has been used to investigate the self-association in aqueous buffered solution of a bis-intercalator, Acridine Homodimer (AcrH), and its hetero-association with the aromatic dye, Ethidium Bromide (EB).

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, EarlyView.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

Comparing Fragmentation Trees from Electron Impact Mass Spectra with Annotated Fragmentation Pathways [PDF]

, 2012
Electron impact ionization (EI) is the most common form of ionization for GC-MS analysis of small molecules. This ionization method results in a mass spectrum not necessarily containing the molecular ion peak.

Crystals as Rockets: Modulation of the Salient Temperature in Cocrystals by Solvent Mixture Composition

Angewandte Chemie, EarlyView.
Compositionally engineered mixed solvated cocrystals enable modulation of thermosalient actuation. Guest ratio controls thermosalient temperature and propulsion intensity, providing a tunable platform for designing crystalline systems that exhibit stimuli‐responsive mechanical motion.

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Novel acridine-based thiosemicarbazones as ‘turn-on' chemosensors for selective recognition of fluoride anion: a spectroscopic and theoretical study [PDF]

Royal Society Open Science, 2018
New thiosemicarbazide-linked acridines 3a–c were prepared and investigated as chemosensors for the detection of biologically and environmentally important anions. The compounds 3a–c were found selective for fluoride (F−) with no affinity for other anions,

The gentisic acid-based deep eutectic solvent mediated green synthesis of acridines

Catalysis Communications, 2023
A novel gentisic acid-based deep eutectic solvent (ETPPBr/GA-DES) was prepared by mixing of ethyltriphenylphosphonium bromide (ETPPBr) and gentisic acid (GA = 2,5-dihydroxy-benzoic acid), and its structure fully investigated by using the FT-IR, TGA/DTA ...
