Abstract

Among many other applications femtosecond spectroscopy has been used to reveal details of excitation energy (exciton) relaxation and transfer in various types of chromophore complexes One of the most fascinating object in this context is the light harvesting complex located in the photosynthetic unit of bacteria and higher plants /1/ But of actual interest are also dendrimers forming artificial antennae systems where similar definite spatial arrangement of chromophores can be achieved as in biological antennae.
