| Abstract: | The femtosecond dynamics of excitation relaxation of the zinc porphyrinate trimer was studied by the pumping—scanning method. The obtained results were examined using semi-empirical quantum chemical calculations. The dynamics of excitation relaxation shows that the application of similar systems as models for studying photosystems and development of artificial analogs of natural photosynthetic centers is promising. An explanation for the observed coherent dynamics of exciton bands was proposed. |
