Journal ArticleDOI
Characterization and magnetic properties of a "super stable" radical 1,3-diphenyl-7-trifluoromethyl-1,4-dihydro-1,2,4-benzotriazin-4-yl.

TL;DR: In this paper, it was shown that 1,3-Diphenyl-7-trifluoromethyl-1,4-dihydro, 1,2, 4-benzotriazin-4-yl (4), prepared in high yield via the catalytic oxidation of the corresponding amidrazone 5 by using Pd/C (1.6 mol %) and 1,8-diazabicyclo[5.0]undec 7-ene (0.1 equiv) in air,
Journal ArticleDOI
A DFT study of the ground state multiplicities of linear vs angular polyheteroacenes.
TL;DR: An analysis based on the SOMO-SOMO energy splittings, their spatial distributions, and the spin density populations for the triplet states is presented to clarify the factors that determine their ground state multiplicities.
Journal ArticleDOI
Route to benzo- and pyrido-fused 1,2,4-triazinyl radicals via N'-(het)aryl-N'-[2-nitro(het)aryl]hydrazides.
Andrey A. Berezin,Georgia A. Zissimou,Christos P. Constantinides,Yassine Beldjoudi,Jeremy M. Rawson,Panayiotis A. Koutentis +5 more
TL;DR: A two-step route to 1,3-disubstituted benzo- and pyrido-fused 1,2,4-triazinyl radicals is presented and requires a modification for aceto- and trifluoroacetohydrazides that involved a multistep synthesis of asymmetrically 1,1-diaryl-substituting hydrazines.
Journal ArticleDOI
Multifunctional Dithiadiazolyl Radicals: Fluorescence, Electroluminescence, and Photoconducting Behavior in Pyren-1'-yl-dithiadiazolyl.
Yassine Beldjoudi,Mitchell A. Nascimento,Yong Joo Cho,Hyeonghwa Yu,Hany Aziz,Daiki Tonouchi,Keitaro Eguchi,Michio M. Matsushita,Kunio Awaga,Igor O. Osorio-Román,Christos P. Constantinides,Jeremy M. Rawson +11 more
TL;DR: Comparative studies between the energies of the frontier orbitals of pyren-1'-yl nitronyl nitroxide and 1 reveal that the energy mismatch and poor spatial overlap between the DTDA radical SOMO and the pyrene π manifold in 1 efficiently inhibit the non-radiative electron-electron exchange relaxation pathway previously described for 2.
Journal ArticleDOI
Preparation of Blatter Radicals via Aza-Wittig Chemistry: The Reaction of N-Aryliminophosphoranes with 1-(Het)aroyl-2-aryldiazenes.

TL;DR: Reacting N-aryliminophosphoranes with 1-(het)aroyl-2-aryldiazenes in preheated diphenyl ether at 150-250 °C for 5-25 min affords in most cases the 1,3-diaryl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yls (aka Blatter radicals) in moderate to good yields.
