The cover picture shows the fourfold oxidative photocyclization and the significantly differing electrochemical behavior of tetrakis[β‐(thienyl)‐ p ‐styryl]methane and the cyclization product tetrakis(naphthothienyl)methane. Whereas the styryl derivative decomposes upon anodic oxidation, the naphthothienyl derivative displays an oxidative polymerization in cyclic voltammetry. Besides significant bathochromic shifts in the absorption and emission spectra as a consequence of pronounced intramolecular electronic coupling, tetrakis[(hetero)phenanthryl]methanes show remarkable Stokes shifts and are of interest as blue‐violet emitters. The article by T. J. Zimmermann and T. J. J. Müller on p. 2269ff. highlights the synthesis and electronic properties of the hitherto unknown class of tetrakis[(hetero)phenanthryl]methanes.
