Functional polystyrenes (ASAPS) with salicylic acid (ASA) ligands on side chains were prepared with chloromethylated polystyrene (CMPS) as starting substance via twostep polymer reactions

phasetransfer catalytic esterification with sodium glyoxylic acid as reagent and Schiff reaction with 5\|aminosalicylic acid in a homogeneous system. The functional polymer ASAPS was allowed to be coordinated and chelated with Eu(Ⅲ) ion

obtaining polymerrare complex ASAPSEu(Ⅲ). The luminescence property of this complex was preliminarily examined. The experimental results show that with the phasetransfer catalysis action of quaternary ammonium salts

the esterification reaction between the chloromethyl groups of CMPS in organic phase and sodium glyoxylate in water can be carried out effectively

forming a lineartype and aldehyde (AL) groupfunctionalization polystyrene ALPS. The structure of the phasetransfer catalysts and the polarity of the solvents affect the phasetransfer catalytic reaction greatly. The complex ASAPSEu(Ⅲ) possesses the characteristic fluorescence emission

and a remarkable antenna effect can be produced.
