Abstract

Summary form only given: Nonlinear absorption of metallated tetraphenylporphyrin (TPP), halogene substituted TPP and bis-TPP covalent ensembles is studied in a wide spectral range of visible and infrared light. Advantages of complexation with Pb and π-conjugation of bis-porphyrin ensembles for reverse saturable and two-photon absorptions were demonstrated. The compounds are useful for optical power limiting applications.
