By reacting alkynylthiacalix[4]arenes with polyethylene glycol azido compounds,a series of novel thiacalix[4]arene 1,2,3-triazole-polyethylene glycol netty polymers were conveniently prepared in good yields.Their structures and morphologies were studied by ^1H NMR,IR.and elemental analysis and SEM images.On average,approximately 28-31 thiacalixarene units exist in each polymeric molecule.These novel polymers possess excellent adsorption ability for both cationic and anionic dyes.The saturation adsorption capacity for Congo red reached 1.3-1.4 mmol/g.They exhibit high and stable adsorption ability in the scope of pH 5-9,and maintain good properties in five cycles. 展开更多
