Beginning from the first steps of a long standing and fruitful cooperation with Prof. G. Ponomarev and Dr. A. Shulga and inspired by their high professional level, a variety of highly organized multiporphyrin complexes of various morphology as well as nanoassemblies based on semiconductor quantum dots and porphyrins were formed based on a “bottom-up” approach. Using steady-state, time-resolved methods in combination with high spectral resolution experiments some specific and/or rare processes of excitation energy relaxation were found and discussed (fluorescence line narrowing and spectral hole burning, triplet-triplet energy transfer in dimers, photoinduced electron transfer at low temperature, distant superexchange charge transfer, etc.).
