However, due to the low solubility of PEDOT, some copolymers incorporating EDOT and 3-alkylthiophene, pyrenes, or fluorenes
have been synthesized.
Indeed, the DWH oil is mainly composed of PAH: naphthalenes, fluorenes
, and phenanthrenes (Forth et al.
The degree of intra-molecular charge transfer in 9-(1, 3- dithiol-2-ylidene) fluorenes
bearing fused thiophene and 2,5-dihydrothiophene units has been investigated by ultraviolet-visible spectroscopy.
The molecular thermometer consists of dyes such as porphyrins, metallo-porphyrins, fluorenes
, and triphenylamines.
Common PAHs include phenanthrenes, fluorenes
, naphthalenes, fiuoranthrenes, and pyrenes, many of which are known mutagens and carcinogens (19-22).
Major PAH components of DEP include phenanthrenes, fluorenes
, naphthalenes, fluoranthrenes, and pyrenes (7).
The structure, an alternated copolymer of fluorene
and terpyridine, namely, poly[(9,9-bis(3-((S)-2- methylbutylpropanoate))fluorene-alt-6,6'-(2,2':6' ,2" terpyridin-6-yl)] (LaPPS71), is depicted in Figure 1.
ClSFDBAO and SFDBAOO from a mixture of dichloromethane/alcohol and a mixture idines in ClSFDBAO are incompletely perpendicular with fluorene
plane according to X-ray crystallography, obviously different from spirobifluorenes.
For example, a combination of three metabolites of fluorene
(row 23 of Figure 6) occurs in at least one-third of U.S.
The relative abundance of dibenzothiophene (SF) in TFs, which include fluorene
(F), dibenzothiophene (DBT) and dibenzofuran (DBF), is very high, even up to 78.94% (Fig.
The facile functionalization at the 9-position of fluorene
unit also offers the ability to control interchain interactions, crosslinking ability, and electrical and optical properties.
His thesis, entitled "Synthesis of Fluorene
Based Monomers for Application in Polymerization Reactions Aimed at the Synthesis of Thermally Stable Polyfluorene Based Blue Emitting Materials for Application in Opto-electronic Devices," explores synthetic routes to new substituted dibromofluorenes.
