Cooperative enhancement of two-photon absorption in self-assembled zinc-porphyrin nanostructures
Femtosecond two-photon absorption (2PA) spectra were measured of a series of butadiynelinked zinc-porphyrin oligomers assembled in single- and double-strand linear and cyclic structures containing 6, 12 or 24 porphyrin units, in the excitation wavelength range 900–1600 nm. We observe s...
