Nonlinear absorption and excited state dynamics of porphyrin and phthalocyanine in the presence of explosive molecules

- Nonlinear absorption of a porphyrin, phthalocyanine studied in presence of explosive molecules.
- Excited state decay times calculated in the presence of explosive molecule.
- NLA coefficients increased with increase in concentration of quencher molecules.
- Excited state decay times decreased with increase in concentration of quencher molecules.
