      The suppression of columnar π-stacking in 3-adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl 

      Constantinides, Christos P.; Berezin, Andrey A.; Zissimou, Georgia A.; Manoli, Maria; Leitus, G. M.; Koutentis, Panayiotis Andreas (2016)
      3-Adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl(4) crystallizes as chains of radicals where the spin bearing benzotriazinyl moieties are isolated from each other. Magnetic susceptibility studies in the 5-300 K ...

      Synthesis and Characterization of Isodiphenylfluorindone and Isodiphenylfluorindinone 

      Zissimou, Georgia A.; Kourtellaris, Andreas; Koutentis, Panayiotis A. (2018)
      Isodiphenylfluorindone 6 and isodiphenylfluorindinone 7 are synthesized. The former reacts with NaOMe to give the 13-methoxyisodiphenylfluorindone 22 (95%), while the latter reacts with 70% perchloric acid to give the ...

      Tetraphenylhexaazaanthracenes: 16π Weakly Antiaromatic Species with Singlet Ground States 

      Constantinides, Christos P.; Zissimou, Georgia A.; Berezin, Andrey A.; Ioannou, Theodosia A.; Manoli, Maria; Tsokkou, Demetra; Theodorou, E.; Hayes, Sophia C.; Koutentis, Panayiotis Andreas (2015)
      Tetraphenylhexaazaanthracene, TPHA-1, is a fluorescent zwitterionic biscyanine with a closed-shell singlet ground state. TPHA-1 overcomes its weak 16π antiaromaticity by partitioning its π system into 6π positive and 10π ...
