Photoelectrochemistry of Nanocrystalline Aggregates of Cyanine Dyes on the Semiconductor Electrodes

Spontaneous aggregation of cyanine dyes in solution and at liquid/solid interfaces is perhaps the most prominent example of molecular self-organization. The optical properties of aggregates of cyanine dyes differ radically from those of single molecules, being strongly dependent on a number of associated dye molecules and on the aggregate's structural features; the aggregates of cyanine dyes may be thus considered as the model systems for studies on the Q-sized molecular nanocrystals.
