On the front cover Hidemitsu Uno, Ehime University, and colleagues have prepared potential selective near-infrared (NIR) dyes by the fusion of boron-dipyrromethene (BODIPY) chromophores. Uno et al. designed these π-fused bis-BODIPY chromophores to show intensive absorption and strong fluorescence in the near-infrared region and not to have any strong absorption in the visible region.

The inside cover from Xin-Dong Jiang, Henan University, and co-workers demonstrates the synthesis of a novel BODIPY from a 3,4,4a-trihydroxanthene-fused pyrrole, that is non-cytotoxic and so is suited to the labeling of living cells in the NIR region.
