Study on the volatility of halogenated fluorenes
Chemosphere, 2016This work reports the experimental determination of relevant thermophysical properties of five halogenated fluorenes. The vapor pressures of the compounds studied were measured at different temperatures using two different experimental techniques. The static method was used for studying 2-fluorofluorene (liquid and crystal vapor pressures between 321 ...

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.

Mutagenicity of methylated fluorenes and benzofluorenes
Mutation Research Letters, 1981Methylated fluorenes were assayed for mutagenic activity towards Salmonella typhimurium TA98 and TA100. None of these methylfluorenes were mutagenic in the absence of metabolic activation. In the presence of 9000 X g supernatant from Aroclor-induced rats, 9-methylfluorene and 1,9-dimethylfluorene were active towards TA98 and TA100.

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.

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.

Macrospirocyclic Oligomers Based on Carbazole and Fluorene
Organic Letters, 2010Monodisperse macrospirocyclic oligomers were prepared using self-condensation of the Friedel-Crafts reaction. Through the C-9s of the central fluorene units of four surrounding oligofluorenes, four carbazole units are connected in a series to form a macrocyclic core.
