Abstract
Reports have suggested that polar porphyrins such as tetraphenylporphine tetrasulfonate (TPPS) can serve as carbohydrate receptors in water. Here we find that TPPS shows changes in UV-visible absorption when treated with glucose, but that these are best explained by altered aggregation states and not by formation of a closely-bound complex.
摘要
有报道称，诸如四苯卟啉四磺酸盐（TPPS）之类的极性卟啉在水中可作为碳水化合物受体。在此，我们发现TPPS在与葡萄糖处理时，其紫外可见吸收会发生变化，但这些变化最好用聚集状态的改变来解释，而非紧密结合复合物的形成。
