Molecular Engineering of Nonplanar Porphyrin and Carbon Nanotube Assemblies: A Linear and Nonlinear Spectroscopic and Modeling Study

Figure 3

PL emission of TPP and its 10 : 1 SWNT composite upon photoexcitation in the Soret band region at 417 nm (a) and the Q band region at 590 nm (b) as a function of concentration for high concentration solutions. Also shown is the ratio of composite to porphyrin emission as a function of concentration upon excitation at both wavelengths. The 2-mm cuvette was used for all solutions at concentrations higher than 0.001 mg/mL.
