Fungal degradation of fluorene
Chemosphere, 2000A selection of 30 strains of micromycetes known as good degraders of polychlorinated aromatic compounds, mostly isolated from soil and belonging to various taxonomic groups, have been investigated to degrade fluorene. Toxicity assays, first evaluated on solid media, have shown high growth inhibition at concentrations above 0.001 g l-1 only towards 23 ...

In fluorene-1-carboxylic acid, C14H10O2, the sole hydrogen bond is of the cyclic dimer type about a center of symmetry. The carboxyl H atom is ordered. Distances in the fluorene core are very similar to those in fluorene itself; the fluorene core dihedral angle is, however, larger than in fluorene.

Dispiro(fluorene-9,4'-[1,3]dithiolane-5',9''-fluorene)
Acta Crystallographica Section C Crystal Structure Communications, 1995The crystal structure of dispiro(fluorene-9,4'-[1,3]dithiolane-5',9-fluorene), C 27 H 18 S 2 , is reported. The C4-C5 bond connecting the two fluorenyl groups is 1.580 (4) A which is slightly longer than the C-C bond lengths [1.36-1.49 A] in other 1,3-dithiolanes.

Vapor pressure measurements on fluorene and methyl-fluorenes
Fluid Phase Equilibria, 2004Vapor pressures, molar enthalpies of sublimation, and molar enthalpies of vaporization of fluorene, 9-methyl-fluorene, and 1-methyl-fluorene have been determined by the transpiration method. Results were tested for internal consistency and compared with available literature data.

Anisotropic electron mobility in fluorene-PPV and fluorene-MEH-PPV
Molecular Physics, 2016ABSTRACTPolyfluorene copolymers are attractive semiconductor materials, in particular for applications in the organic electronics field. They are versatile to be chemically modified and allow a tuning of the emission to cover the entire visible spectrum.

Novel Soluble Fluorene–Thienothiadiazole and Fluorene–Carbazole Copolymers for Optoelectronics
Macromolecular Symposia, 2010AbstractSummary: Optical, photophysical, electrochemical and photoelectrical properties of novel soluble low‐bandgap fluorene – thienothiadiazole based copolymers (CHTF and CDTF) and luminescent fluorene – carbazole copolymers, (CFCzE and CFCZA) were studied.
