Can H-aggregates serve as light-harvesting antennae? Triplet-triplet energy transfer between excited aggregates and monomer thionine in aerosol-OT solutions
Article Abstract:
Research was conducted to examine the concept of directional energy transfer between different dye aggregates and monomer thionine by confining them in a reverse micellar environment. Varying amounts of monomer, dimer and higher order aggregates were obtained in dilute dye solutions by controlling the ratio of (dye)/(aerosol-OT). Results suggest the possibility of using H-type dye aggregates as antenna molecules to harvest light energy.

Harvesting infrared photons with tricarbocyanine dye clusters
Article Abstract:
The absorption of 4,5-benzoindotricarbocyanine dye (IR 125) in the infrared is tuned by controlling the type of aggregation in different media. The presence of long-lived transient species has confirmed the charge separation in these films following IR excitation.

Photoinduced charge separation and stabilization of clusters of a fullerene-aniline dyad
Article Abstract:
Fullerene-aniline dyad creates optically transparent microscopic clusters in mixtures of acetonitrile and toluene at room temperature. The charge stabilization processes are very efficient in the clusters of the dyads compared with homogenous medium.
