一种新的配体，5-巯基甲基四唑，适用于高发光（量子产率高达60%）的水溶性CdTe纳米晶体的直接胶体合成。在合成中，5-巯基甲基四唑的行为类似于广泛使用的巯基乙酸，提供了所得纳米晶体在甲醇中的溶解度的额外优点。此外，5-巯基甲基四唑封端的纳米晶体具有独特的能力，可逆地形成精细的3D网络（水凝胶）后，添加金属盐。
A novel ligand, 5-mercaptomethyltetrazole, is applied to the direct colloidal synthesis of highly luminescent (quantum yield of up to 60%) water-soluble CdTe nanocrystals. In the synthesis the 5-mercaptomethyltetrazole behaves analogously to the widely used thioglycolic acid, providing the additional advantage of solubility of the resulting nanocrystals in methanol. Moreover, the 5-mercaptomethyltetrazole-capped nanocrystals possess the unique ability to reversibly form fine 3D networks (hydrogels) upon the addition of metal salts.
