      Normal and defective perylene substitution sites in alkane crystals 

      Leontidis, Epameinondas; Heinz, H.; Palewska, K.; Wallenborn, E. -U; Suter, U. W. (2001)
      The substitution nature of perylene in polycrystalline solid alkane matrices was examined. Low temperature excitation-emission matrix spectroscopy was used to determine substitution sites in alkane matrices from hexane to ...

      Novel BODIPY-based conjugated polymers donors for organic photovoltaic applications 

      Economopoulos, Solon P.; Chochos, Christos L.; Ioannidou, Heraklidia A.; Neophytou, Marios; Charilaou, C.; Zissimou, Georgia A.; Frost, J. M.; Sachetan, T.; Shahid, M.; Nelson, J.; Heeney, M.; Bradley, D. D. C.; Itskos, Grigorios; Koutentis, Panayiotis Andreas; Choulis, Stelios A. (2013)
      Five new polymers based on the 4,4'-difluoro-4-bora-3a,4a-diaza-s-indacene core (BODIPY) chromophore moiety have been synthesized as low bandgap polymers for optoelectronic applications. The polymers exhibited high solubility ...

      Simple and accurate computations of solvatochromic shifts in π → π* transitions of aromatic chromophores 

      Heinz, H.; Suter, U. W.; Leontidis, Epameinondas (2001)
      A new approach is introduced for calculating the spectral shifts of the most bathochromic π → π * transition of an aromatic chromophore in apolar environments. As an example, perylene in solid and liquid n-alkane matrixes ...

      Triplet excitation energy dynamics in metal-organic frameworks 

      Lin, J.; Hu, X.; Zhang, P.; Van Rynbach, A.; Beratan, David N.; Kent, C. A.; Mehl, B. P.; Papanikolas, J. M.; Meyer, T. J.; Lin, W.; Skourtis, Spiros S.; Constantinou, Martha G. (2013)
      Metal-organic frameworks (MOFs) are appealing candidates for use in energy harvesting and concentrating because of their high chromophore density and structural tunability. The ability to engineer electronic excitation ...
