摘要：

We have shown that the ICT fluorophores with longer alkyl substituents at the amino nitrogen atom of p-aminobenzoic acid, p-hexyl, methylaminobenzoic acid (HMABOA) and p-hexyl,ethylaminobenzoic acid (HEABOA), bind more strongly to CTAB and CTAC micelles and in CTAC micelle these fluorophores show higher ICT to LE fluorescence intensity ratio.
