The cover picture shows part of the synthetic possibilities opened now by using elemental fluorine as a starting material. Mixtures of F~2~ with inert gases such as N~2~ are commercially available or easily prepared from commercial 95% fluorine. During the last 15 years, chemists started to accept the notion that F~2~ could be used for fluorination purposes. More recently, they slowly started to get acquainted with yet another side of this element − its ability to perform difficult reactions leading to fluorine‐free derivatives. Thus, the most reactive element of the periodic table is an excellent tool for versatile regio‐ and stereospecific reactions which can not be performed without its “help”. Representative examples are presented in the Microreview by S. Rozen on p. 2433 ff.

## Abstract **The cover picture shows** a typical example of a fluorophore‐heterofullerene conjugate which represents a molecular energy transducer. The heterofullerene moiety is the C~59~N cluster and the fluorophore is, in this case, phenanthrene. In a similar way other fluorophores such as fluor
