Studies on aggregation of fluorescein derivatives by electroabsorption spectroscopy
Concentration dependence of linear and nonlinear optical property in a series of di-n-butyl fluorescein derivatives was investigated by absorption and electroabsorption measurements, in order to examine the aggregativeness of them. It was found that Br substitution prevents molecular aggregation which affects the third-order nonlinearity.
