2-(2,3,4,5,6-Pentafluorophenyl)-1H-benzo[d]imidazole, a fluorine-rich building block for the preparation of conjugated polymer donors for organic solar cell applications
Neophytou, Marios; Ioannidou, Heraklidia A.; Ioannou, Theodosia A.; Chochos, Christos L.; Economopoulos, Solon P.; Koutentis, Panayiotis Andreas; Itskos, Grigorios; Choulis, Stelios A. (2012)We have introduced the pentafluorophenyl substituted benzimidazole as a building block of conjugated polymers for optoelectronic applications. We present the synthesis of a copolymer bearing fluorene as the comonomer. A ...

Manipulating the singlet-triplet energy gaps of arene-fused bis(1,2,3-dithiazoles): A computational study
Constantinides, Christos P.; Ioannou, Theodosia A.; Koutentis, Panayiotis Andreas (2013)Benzo- and azino-fused bis(1,2,3-dithiazoles) were investigated computationally using density functional theory (DFT) in an attempt to relate structure to ground state multiplicity preference. Structural changes on 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 ...
