Exciton spectra and the microscopic structure of self-assembled porphyrin nanotubes.
The optical properties of tubular aggregates formed by self-assembly of zwitterionic meso-tetra(4-sulfonatophenyl)porphyrin (TPPS4) molecules are studied through a combination of experimental and theoretical techniques. The interest in these systems, with diameters of 18 nm and lengths extending up to micrometers, derives from their strong interaction with light and their similarity to natural ...
متن کاملEfficient exciton transport in layers of self-assembled porphyrin derivatives.
The photosynthetic apparatus of green sulfur bacteria, the chlorosome, is generally considered as a highly efficient natural light-harvesting system. The efficient exciton transport through chlorosomes toward the reaction centers originates from self-assembly of the bacteriochlorophyll molecules. The aim of the present work is to realize a long exciton diffusion length in an artificial light-ha...

DNA, well-known as the predominant molecule for storage of genetic information in biology and biochemistry, has also been recognized as a useful building material in the field of nanotechnology. DNA provides basic building blocks for constructing functionalized nanostructures with four major features: molecular recognition, self-assembly, programmability, and predictable nanoscale geometry. The...
متن کاملStructure vs. excitonic transitions in self-assembled porphyrin nanotubes and their effect on light absorption and scattering.
The optical properties of diprotonated meso-tetrakis(4-sulphonatophenyl)porphyrin (TPPS(4)) J-aggregates of elongated thin particles (nanotubes in solution and ribbons when deposited on solid interfaces) are studied by different polarimetric techniques. The selective light extinction in these structures, which depends on the alignment of the nanoparticle with respect to the polarization of ligh...
