Abstract

In this study, the spectroscopic measurements of the second generation dendritic zinc phthalocyanine (phthalocyanine dendrimer with tris) 2 were made and its potential to be used in optoelectronic applications was investigated. To examine the intramolecular energy transfer properties, fluorescence quantum yields were calculated and the contribution of first (phthalocyanine dendrimer with triethyl methanetricarboxylate) 1 and second 2 generation dendrimers to this energy transfer was investigated. The photoluminescence properties and optical band gap of the second generation zinc phthalocyanine 2 were investigated depending on the temperature. In addition, the quantum efficiency of singlet oxygen was calculated to evaluate the usability of this compound in photodynamic therapy. Also, aggregation behavior of compound 2 was examined in different solvents (DMF, DMSO and THF) and different concentrations in THF. To the best of our knowledge, this is the first study to examine the photoluminescence properties and temperature dependent changes of dendritic phthalocyanines.
