Molecular Engineering of Nonplanar Porphyrin and Carbon Nanotube Assemblies: A Linear and Nonlinear Spectroscopic and Modeling Study
Figure 1
(a) Normalized UV-VIS absorption spectra of TPP, DETPP, tTETPP, cTETPP, HETPP, and OETPP and their (1 : 1) SWNT composites (0.001 mg/mL, DMF, 25°C). (b) The VIS-NIR absorption spectra of DETPP, its (1 : 1) SWNT composite, and a dispersion of SWNT alone in DMF show the characteristic Q Bands and Van Hove peaks and show that the absorption spectrum of the composite solution is intermediate between that of the porphyrin and the SWNT with characteristics of both.
