( 2 ) an aminobenthiazole schiff base has been synthesized as a new fluorescence carrier by reacting 2 - aminobenthiazole with p - allyoxybenzoldohyde. the new kind of schiff base can be utilized for preparing an optical sensor, used for determining furazolidone based on the fluorescence quenching. aminobenthiazole schiff base immobilized on a glass plate surface by covalent bonding can circumvent the leakage of the fluorephore from the sensor surface and guarantee a relatively long working lifetime
