✦ Synopsis

The fluorescence kinetics of a new single crystal, R-phycoerythrin (R-PE), has been studied by picosecond laser spectroscopy. An excitonic band, which is much more narrow than that of the molecular fluorescence, is observed. At high pump density, superradiance of excitons in the bulk pure single crystal is recorded. The experimental results of fluorescence kinetics and exciton superradiance of R-PE crystal demonstrate that exciton energy transfer is natural, effective and rapid. It is concluded that excitons play an important role in energy transfer in the antennae of photosynthetic systems.

Time-resolved emission spectroscopy of "push-pull" stilbene derivatives has revealed the presence of an anomalous emission band appearing in the 5200-5600 8, spectral range. This anomalous band appears only in derivatives where the donor group is able to twist and depends on the solvent polarity, co
