Abstract

<p>Aromatic compounds(1-4)connected with gallic acid bearing amphiphilic oligo(ethylene glycol)groups were synthesized using an ethylene diamine spacer. Their thermoresponsive properties(lower critical solution temperature behaviors)were investigated on the basis of their solute concentration dependence and the effect of salt or organic solvent addition in their aqueous solutions. In addition, temperature-sensitive fluorescence properties induced via aggregation during phase transition of the aromatic compounds(4 and 8)bearing pyrenyl groups were investigated.</p>
