Fluorescence spectra of 4-methyl-7-anilinocoumarin (MAC), 4-methyl-7-diethylaminocoumarin (MDC) and dansyl-L-alanine (DNS-L-Ala) were measured in aqueous solutions of poly (oxy ethylene) nonylphenyl ethers (NP) of various poly (oxyethylene) chain lengths.
CMC could be determined by the measurement of the solubilization curves of fluorescent probes into surfactant micelles. The polarities of the solutions in which MAC and MDC were solubilized increase with increasing poly (oxyethylene) chain length. On the other hand, the polarity of the solution in which DNS-L-Ala was solubilized decreases.
