We report a new family of oligomeric alkyl phosphine ligands for nanocrystal quantum dots. These oligomeric phosphines show effective binding affinity to quantum dot surfaces. They form thin and secure organic shells that stabilize quantum dots in diverse environments including serum and polymer matrices. They maintain the initial as-grown photoluminescence quantum yield of the quantum dots and enable homogeneous incorporation into various matrices. They present a chemically flexible structure that can be used for further chemistry, such as cross-linking, copolymerization, and conjugation to biomolecules.
我们报道了一种用于纳米晶体量子点的新型低聚烷基膦配体家族。这些低聚膦对量子点表面显示出有效的结合亲和力。它们形成薄而稳定的有机壳层，可在包括血清和聚合物基质在内的多种环境中稳定量子点。它们保持量子点最初生长时的光致发光量子产率，并能均匀地掺入各种基质中。它们具有化学灵活的结构，可用于进一步的化学反应，如交联、共聚以及与生物分子偶联。
