      Effective exchange coupling in alternating-chains of a π-extended 1,2,4-benzotriazin-4-yl 

      Constantinides, Christos P.; Berezin, Andrey A.; Manoli, Maria; Leitus, G. M.; Bendikov, M.; Rawson, J. M.; Koutentis, Panayiotis Andreas (2014)
      Air stable 1,3,7-triphenyl-1,4-dihydrothiazolo[5′,4′:4,5] benzo[1,2-e][1,2,4]triazin-4-yl packs in 1D π stacks made of radical pairs with alternate short and long interplanar distances. The magnetic susceptibility exhibits ...

      Liquid-crystalline phase behavior in a zwitterionic tetraazapentacene 

      Riley, A. E.; Mitchell, G. W.; Koutentis, Panayiotis Andreas; Bendikov, M.; Kaszynki, P.; Wudl, F.; Tolbert, S. H. (2003)
      A 5,7-dioctadecylquinoxalinophenazine zwitterion 1 has been investigated to determine its thermal phase behavior. A combination of differential scanning calorimetry (DSC), variable temperature low- and high-angle X-ray ...

      A magnetostructural investigation of an abrupt spin transition for 1-phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl 

      Constantinides, Christos P.; Berezin, Andrey A.; Zissimou, Georgia A.; Manoli, Maria; Leitus, G. M.; Bendikov, M.; Probert, M. R.; Rawson, J. M.; Koutentis, Panayiotis Andreas (2014)
      1-Phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl is the first example of a hydrazyl radical that shows a reversible sharp spin transition fully completed within 5(1) K. The nominally first-order transition ...

      Spin-triplet excitons in 1,3-diphenyl-7-(fur-2-yl)-1,4-dihydro-1,2,4- benzotriazin-4-yl 

      Constantinides, Christos P.; Carter, E.; Murphy, D. M.; Manoli, Maria; Leitus, G. M.; Bendikov, M.; Rawson, J. M.; Koutentis, Panayiotis Andreas (2013)
      7-(Fur-2-yl)benzotriazinyl 1 is the first example of a hydrazyl radical dimer with a thermally accessible triplet state. The triplet exciton (|D| = 0.018 cm-1, |E| = 0.001 cm-1) was observed by solid-state VT-EPR spectroscopy ...
