Inorganic-organic hybrid materials have been obtained at room temperature in aqueous solution without using the templates of surfactants. The materials are care- fully characterized by anion-exchange measurement, ele- ments analysis, X-ray diffraction, and infrared spectroscopy. Notably, the anion-exchange capacity of the samples (3.9 mmol·g-1) is even higher than anion-exchangeable resins. Interestingly, both small and large anions could be easily exchanged into the samples due to the plasticity of the sam- ples, along with the phase transition.
