What is Energy transfer between J-aggregates of quinocyanine dyes in the sodium alginate films about?

New optical materials such as the J-aggregate of quinocyanine dyes in polymer films were fabricated and studied. 1,1'-diethyl-2,2'-cyanine chloride and iodide (dye I, X = CI or I); as well as 5,6,5',6'-dibenzo-l,l'-diethyl-2,2'-cyanine chloride (dye II) in the sodium alginate (SA) films easily formed the J-aggregate, characterized by a sharp absorption of the J-band and the resonance fluorescence. The evidence of long distance energy transfer between extended donor and extended acceptor J-aggregates was presented. The critical distance of the energy transfer of about 55 ,~ was estimated on the base of spectral and fluorescence lifetime measurements.
