. A product comprising a substrate on which is provided a fullerene thin film. A method of manufacturing a product comprising a substrate on which is provided a fullerene thin film, comprising providing on a substrate of a thin film comprising a fullerodendrimer and decomposing of at least the dendrimer constituting the fullerodendrimer by heating in a non-oxidizing atmosphere.
A concise and efficient photoinduced rearrangement of (E)-3-arylvinyl-4H-chromen-4-ones for the synthesis of benzoaryl-5-yl(2-hydroxyphenyl)methanones is described. Benzoaryl-5-yl-(2-hydroxyphenyl)methanones were obtained in 77–95% yields via the irradiation of (E)-3-arylvinyl-chromones in the 95% EtOH with a high-pressure mercury lamp at room temperature under Ar atmosphere. The reported method provides
The sign of circularly polarized luminescence (CPL) of a chiral 21-helical columnar organic fluorophore was successfully controlled in the solid-state by changing an achiral fluorescence component molecule, and not by using a chiral component molecule with opposite chirality.

Polycyclic aromatic hydrocarbons were found to be promising universal bases in PNA.DNA double helices. Several of the arenes paired promiscuously with any of the four canonical bases. However, the stabilities of the duplexes depended on the size and shape of the arene. (C) 2007 Elsevier Ltd. All rights reserved.
