    Novel multichromophoric energy transfer cassettes based on functionalized BODIPY dyes
    (2012) Çeltek, Gizem
    Energy necessity is one of the leading problems in the world due to the developing technologies and strategies. There are many energy sources, which are being used for years, however; conversion and transfer of the energy is a problem in many fields due to energy loss. In this manner, the efficiency of energy transfer is very crucial. For this purpose, we have designed multichromophoric molecules, which can absorb the light with donor parts, then transfer the energy to the acceptor site. During this process, energy loss is tried to be prevented by lowering the distance between the donor and acceptor Boradiazaindacene (BODIPY) molecules. Three different energy transfer cassettes are synthesized and characterized. The design of the supramolecule, in means of spectral overlap and distance between the donor and the acceptor site are observed to affect the energy transfer efficiency. Through functional design, these molecules absorb and emit light in different wavelengths. Substation of distyryl and tetrastyryl groups to the acceptor BODIPY core changes the emission and absorption maxima. Increasing number of styryl groups attached to the molecule shifts the spectrum to the red part of the visible region. Through rational design, these molecules can be used in applications of energy transfer and broad spectrum absorber purposes.
