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.
These fluorenes can be used as precursors to thermally-stable polyfluorene based materials.
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).
For example, a combination of three metabolites of fluorene (row 23 of Figure 6) occurs in at least one-third of U.
The relative abundance of dibenzothiophene (SF) in TFs, which include fluorene (F), dibenzothiophene (DBT) and dibenzofuran (DBF), is very high, even up to 78.
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.
They can be constructed using a variety of cathode materials including calcium, aluminum and magnesium alloys, and are useful in combination with a variety of hole transport layer materials including PEDOT/PSS (Baytron-P from Bayer), polyanilines and some fluorene copolymers.
