The present invention relates to a new method of cross-coupling aryl moieties comprising reacting an arylhalide with an arylboronic acid in the presence of a palladium compound and a compound comprising a di-alkylphosphine moiety.
A general synthetic approach to polycyclic aromatic hydrocarbons containing a fluoranthene ring system is described. The method entails fusion of an indeno ring to an alternant hydrocarbon via reaction of an aryllithium derivative with cyclohexene oxide.

The present invention relates to various methods of sensitizing and modifying nanosensor platforms. In one embodiment, the present invention provides a method of increasing sensitivity by inhibiting oxidation of one or more 1,4-hydroquinone (HQ) molecules, functionalizing the nanosensor by using one or more diazonium molecules, creating one or more oxidized carbon groups on the nanosensor, and/or depositing one or more metal clusters on the nanosensor.
1 h, and with a high torsion angle in 1 c and 1 d. Radicals 1 c and 1 h form unusual infinite chains with crisscrossing hetero‐co‐facial π–π interactions, whereas radical 1 d forms analogous homo‐co‐facial arrangements. Infinite chains of homo‐co‐facial π–π dimers are found in 1 b, 1 f and 1 g; in the latter the position of the CF3 group controls the slippage of the dimers in the chain. No π–π parallel
