## Abstract The NMR assignments of all carbons of dibenzothiophene and its __S__‐oxides, dibenzofuran, various carbazoles, fluorene and fluorenone have been carried out using deuteriated derivatives and lanthanide shift reagents. Chemical shifts and coupling constants are discussed as a function of
## Abstract Poly(fluorene)‐type materials are widely used in polymer‐based emitting devices. During operation there appears, however, an additional emission peak at around 2.3 eV, leading to both a color instability and reduced efficiency. The incorporation of the carbazole units has been proven to
Abstr anthracene chars heat treated between 500 and 1200°C is developped and applied to d.c. electrical conductivity, paramagnetic susceptibility and apparent density. An inhomogeneous process for the carbonization is proposed, in agreement with recent results on the structure of these chars. acts 3
## Abstract The kinetics of thallation of fluorene with thallium triacetate (TTA) in HOAc‐H~2~SO~4~ solutions led to the rate expression The rate of thallation is found to increase with increasing acid concentration, and a sixth‐order dependence on [H~2~SO~4~] is observed. Decrease in solvent pol
