摘要：

We describe the preparation and characterization of a solvatochromic dye-doped polymer for the detection of polar additives in hydrocarbon blends. This polymer is prepared by inclusion of the strongly solvatochromic Reichardt's dye (RD) into poly(methyl methacrylate) (PMMA). The influence of various parameters on the detection of methanol, tert-butyl alcohol (TEA) and tert-butyl methylether (TBME) in hydrocarbon blends is analysed by u.v.-visible spectroscopy. RD-PMMA spin-coated films can detect repeatedly down to 0.1% (v/v) methanol and TEA and 1.0% (v/v) TBME, which makes them potential candidates of a solvatochromic-based fibre optic chemical sensor for in situ monitoring of octane improvers in gasoline.
