Attempts to apply mechanisms of quantum control to porphyrinoids in solution. Molecules which belong to this class are structural analogs of porphin, a molecule so common in living organisms (for instance in heme and chlorophyll) that it is called the pigment of life. According to theory, two processes can be controlled by light in these molecules: excitation of ring currents in highly symmetric metallated porphyrins and double hydrogen transfer in porphycenes.
Studies of surfaces and interfaces by nonlinear optical spectroscopy. Optical phenomena based on second-order nonlinearity can be effectively utilized to achieve very high selectivity of optical spectroscopy of air/liquid and liquid/liquid interfaces. Application of second harmonic generation or frequency summing for spectroscopic study of oil/water interfaces allows modeling of behavior of molecules adsorbed at cellular membranes.
Photophysical characterization of newly synthesized molecules which can be potentially used as photosensitizers in photodynamical therapy of cancer. Time-resolved, nano- and femtosecond spectroscopy is used as a tool for measurements of photophysical parameters relevant for phototherapeutical application of molecules. The results are then used as feedback information useful for synthesis of improved photosensitizers.
