Facile Preparation Methods for Triarylmethyl‐Type Stable Luminescent Diradicals and Higher Multiradicals

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
A range of synthetic methods for photophysically attractive stable luminescent diradicals have been developed, enabling the preparation of diverse derivatives. Direct substitution of the tris(2,4,6‐trichlorophenyl)methyl radical introduces donor groups to afford acceptor–donor–acceptor luminescent diradicals, while halogenated triarylmethanes are ...

Anion–π interactions influence pKa values

open access: yesBeilstein Journal of Organic Chemistry, 2011
Five 8-(4-R-phenyl)-1-naphthol derivatives were prepared by PdCl2-catalysed electrophilic aromatic substitution. The pKa' values for these 1,8-disubstituted arene naphthols have been measured in acetonitrile/water (R = NO2, 8.42; R = Cl, 8.52; R = H, 8 ...

Synthesis and application of novel heterocyclic dyes based on 11-amino-13H-acenaphtho[1,2-e]pyridazino[3,2-b]quinazolin-13-one [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
A new fused heterocyclic compound, 11-amino-13H-acenaphtho[1,2-e]pyridazino [3,2-b]quinazolin-13-one was synthesized and used to prepare a novel series of heterocyclic mono azo dyes by coupling with various naphthols.

Application of a mechanistic UV/hydrogen peroxide model at full-scale : sensitivity analysis, calibration and performance evaluation [PDF]

open access: yes, 2011
Numerous mechanistic models describing the UV/H2O2 process have been proposed in literature. In this study, one of them was used to predict the behavior of a full-scale reactor.
