Statistics of optical spectra from single-ring aggregates and its application to LH2

Article Abstract:

Studies done on the statistics of the optical spectra of individual ring-shaped molecular aggregates in which the site energies and transfer interactions are perturbed by both weak random disorder and a regular modulation due to a deformation of the ring. An analytical expression for the joined probability distribution of the splitting between the spectrums dominated by two lines and their average position is presented.

Structure, spectroscopy and microscopic model of tubular carbocayanine dye aggregates

Article Abstract:

Cryo-transmission electron microscopy experiments on 3,3-bis(3-sulfopropyl)-5,5', 6,6'-tetrachloro-1,1'-dioctylbenzimidacarbocynine aggregates that reveal double-layer tubular structure is reported. The basis of theoretical analysis of the spectroscopic data is the formation of the inner and outer cylinders by rolling cyanine sheets with a brick-layer structure onto cylindrical surfaces with diameters of 11 and 16 nm.
