The ground state absorption spectra, spectra and lifetimes of the luminescence originating from the lowest S1 (Q(0,0)) and higher S2 (B) excited states of porphyrin core in the dendrimers with ether-linked carbazole dendrons have been studied in detail. The relationship between the molecular design of the dendritic shell and the optical features of the dendrimer core in solution is presented. The influence of the axial ligation of the porphyrin core and the conformational flexibility of the dendritic shell on the luminescent properties of the studied dendrimers is revealed.
