With the goal to identify a computational feasible approach to investigate the absorption properties of PP-containing materials and extended biological systems, we compare the semiempirical sTDA, sTD-DFT and canonical TD-DFT (RPA and TDA) for UV/Vis spectra calculations of porphyrinoids. After a short summary of computational details, we assess diverse DFT functionals regarding their performance for the calculations of absorption energies of the Q-bands. This includes the (for sTDA unsuccessful and unnecessary) attempt to improve the results by an empirical scaling of excitation energies can improve results significantly.
