polycycloalkane is directly fused to the core or fused to a substituent of the core: and a new organic compound usable in the organic light emitting device. Furthermore, the present invention provides a charge carrier extracting, injecting or transporting material which has a polycyclic aromatic hydrocarbon as a core and comprises a derivative in which a substituted or unsubstituted C

Efficient syntheses of the novel, pyrene containing branched building blocks 10, 13, 22, 25 and of a pyrene based core molecule 16 for the construction of dendrimers are reported. The main tool is a Suzuki cross-coupling. The functional groups for further growth are amines and carboxylic acids, which were used in an orthogonally protected fashion. It was proven that the building blocks could be assembled to a low generation dendrimer 17.

Two efficient dye-sensitizedsolarcells have been fabricated by two novel D–D–π–A phenothiazine-based organicdyes (PH2 and PH3) with an encapsulated insulated molecular wire (EIMW) as an auxiliary donor. The cell sensitized by PH2 with EIMW as an auxiliary donor shows a much higher photovoltage (Voc) relative to the reference dye PH1 without EIMW, because the former dye can inhibit dye aggregation

A highly reactive electrophilic bromodifluoromethylthiolating reagent, α-cumyl bromodifluoro-methanesulfenate 1, was prepared to allow for direct bromodifluoromethylthiolation of aryl boron reagents. This coupling reaction takes place under copper catalysis, and affords a large range of bromodifluoromethylthiolated arenes. These compounds are amenable to various transformations including halogen exchange
