采用丁二酸酐插层酯化法，对高结晶性的海链藻β-甲壳素进行了酯化，并对其结晶性进行了表征。由于引入了游离羧基，甲壳素酯晶体在水溶液中对金属离子表现出离子交换能力。溶液重金属离子如Pb 2+结合到β-几丁质琥珀酸酯上给出了特征性的X射线衍射图，表明金属离子的规则排列。这种材料代表了一种新型的有机金属结构，可能导致新的功能。
The highly crystalline β-chitin from diatomThalassiosira weissflogiiwas esterified via intercalation with succinic anhydride followed by simple heating, maintaining the original crystalline order. Due to the introduced free carboxyl groups, the chitin ester crystal showed ion exchange ability for metal cations in aq. solution. Heavy metal cations such as Pb2+bound to the β-chitin succinate gave characteristic X-ray diffraction patterns, indicating regular alignment of metal ions. Such materials represent a new type of organometallic architecture, possibly leading to novel functionalities.
