Natasha A. D. Yamamoto,Leah L. Lavery,Bruno Nowacki,Isabel R. Grova,Gregory L. Whiting,Brent S. Krusor,Eduardo Ribeiro de Azevêdo,Leni Akcelrud,Ana Claudia Arias,Lucimara S. Roman +9 more
TL;DR: In this paper, a new series of donor-acceptor copolymers were synthesized via the Witting route and applied as an active layer in organic thin-films solar cells.
Journal ArticleDOI
Two-photon excitation and optical limiting in polyfluorene derivatives
Daniel S. Correa,Leonardo De Boni,Bruno Nowacki,Isabel R. Grova,Bruno D. Fontes,Paula C. Rodrigues,José Roberto Tozoni,Leni Akcelrud,Cleber Renato Mendonça +8 more
TL;DR: In this paper, the authors reported a new class of polyfluorene derivatives poly(9,9′-n-dihexyl-2,7-fluorenedilvinylene-alt-1,4-phenylenevinylene), poly( 9,9-di-hexylfluorenediylvinylene,alt- 1,4)-phenylene-vinylene)-co-((9, 9′-(3-t-butylpropanoate) fluorene-1.4 s/photon)
