摘要
The synthesis of new chromogenic p(o,m,pcarboxylazo)Calixarenes derivatives through the couping of diazotized o,m,paminobenzene carboxylic acid and calixarenes was described.Their structures were comfirmed by IR,1H NMR and elemental analysis.Their chromogenic properties and UVVis absorption spectra were investigated under different pH conditions.Experimental results show that the synthesized derivatives can be used as new indicators and host
