How Micelles Influence the Optical Limiting Properties of Zinc Porphyrins and J-Aggregates for Picosecond Pulse Trains

In this work, we studied nonlinear dynamics and optical limiting (OL) effects of pulse trains in zinc porphyrins meso-tetrakis methylpyridiniumyl (Zn2+TMPyP) sulfonatophenyl (Zn2+TPPS) porphyrin J-aggregates. The environments were selected as aqueous solutions micelles sodium dodecyl sulfate (SDS) cetyltrimethyl ammonium bromide (CTAB). Our numerical results show that both Zn2+TMPyP Zn2+TPPS are good limiters all solutions. shows the best OL effect. Micelles SDS CTAB produced less than main reason lies first excited singlet state intersystem crossing depending on electronic structures different environments.
