The cover picture shows a series of selected absorption spectra (solid lines) from different substituted pyrrolopyrrole cyanine (PPCy) dyes. This is a new class of chromophores recently developed at the University of Konstanz, located at Lake Constance (upper left). PPCys feature preciously unattainable high fluorescence quantum yields in the near infrared region, which besides other applications makes them attractive as fluorescence labels. One emission spectrum is shown as a dotted line. The core structure of the PPCys is depicted in the upper right corner. Proper substitutions of the core structure allow the generation of dyes absorbing over a broad wavelength range. Details are discussed in the article by A. Zumbusch et al. on p. 3421 ff.
