A new class of biomimetic J-aggregate based on an amphiphilic BF2-azadipyrromethene dye is reported by Z. Chen, F. Würthner, et al. in their Communication on page 5729 ff. The J-aggregate (aggregate II) is formed via kinetically favored metastable aggregate I intermediate and characterized by a sharp and intense J-band at 799 nm. The optical properties and the rod-like morphology of aggregate II resemble those of the natural bacteriochlorophyll J-aggregates found in chlorosomes of green bacteria.
