The influence of additives on the J-aggregation behavior of a cyanine dye

The J-aggregation behavior of the well known 5,5'-6,6'-tetrachloro-1,1'-diethyl-3,3'-bis(sulfobutyl)-benzimidazolocarbocyanine (TDBC) is examined in the presence of the zwitterionic N-dodecyl-N,N-dimethyl-N-carboxymethyl betain.
