Journal ArticleDOI
Two-photon absorption and optical power limiting of bifluorene molecule
Yannick Morel,Adriana Irimia,Pawel Najechalski,Yann Kervella,Olivier Stéphan,Patrice L. Baldeck,Chantal Andraud +6 more
TL;DR: In this paper, the authors studied the nonlinear absorption spectra and optical limiting properties of 2,2′-(9,9-dihexyl) bifluorene.
Journal ArticleDOI
Two-photon absorption spectrum of poly(fluorene)
TL;DR: In this paper, the two-photon absorption (TPA) properties of poly(fluorene) have been characterized in the range 550-680 nm, and a resonance at λ =625 nm is observed with a cross-section of 2×10 −46 cm 4 s/photon-molecule.
Journal ArticleDOI
Photodynamic therapy and two-photon bio-imaging applications of hydrophobic chromophores through amphiphilic polymer delivery.

TL;DR: The synthesis and photophysical properties of two lipophilic quadrupolar chromophores featuring anthracenyl or dibromobenzene combined significant two-photon absorption cross-sections with high fluorescence quantum yield for 1 and improved singlet oxygen generation efficiency for 2, in organic solvents.
Journal ArticleDOI
Fluorene–fluorenone copolymer: Stable and efficient yellow-emitting material for electroluminescent devices
TL;DR: In this paper, a 9-fluorenone monomeric unit (FOne) has been used as comonomer in conjunction with the more classical 9,9-di-n-nonylfluorene unit.
Journal ArticleDOI
Monodisperse fluorene oligomers exhibiting strong dipolar coupling interactions
TL;DR: Well-defined fluorene oligomers were prepared step by step using Suzuki and Yamamoto couplings, while absorption and photoluminescence properties evidenced very large dipolar coupling interactions between fluorenes moieties.
