Abstract

Cyclophane BIMCP-1 undergoes ionic self-assembly with surfactant sodium dodecylbenzenesulfonate (SDBS) at a concentration far below its CMC value to form aggregates with spherical morphology. The rotational restriction of rings in these aggregates facilitates 32-fold enhancement in emission intensity (AIEE) to allow fluorescence based determination of SDBS with 4 μM (1.4 ppm) as the lowest detection limit. Sodium salts of fatty acids and inorganic anions halides, CN^-, HSO₄^-, SO₄ ^2-, H₂PO₄^-, SCN^-, and NO₃^- do not interfere in the estimation of SDBS.
