这项研究检查了量子点 (QD) 与其表面分子之间的电子耦合,作为它们相互作用模式的函数。作为探针,监测和评估了 CdSe QD 和酞菁 (Pcs) 之间的能量转移 (ET),包括轴向酞菁配体的官能化、桥接 QD 供体和 Pc 受体的官能团的体积以及数量功能化的轴向配体。合成了新的硅 PC 及其与 CdSe 量子点的共轭物。通过稳态和飞秒时间分辨吸收光谱研究了 ET 效率和动力学。我们观察到 ET 效率随着官能团体积的增加而降低,这可以通过增加 ET 对之间的空间位阻来解释。此外,

Eight alkoxysilanated phosphorylcholine (PC) compounds were synthesized from CuAAC (copper-catalyzed azide/alkynecycloaddition) and thiol-ene “click” reactions. This methodology will provide simple and efficient routes for the synthesis of alkoxysilanated PC modifiers. To demonstrate modification ability of these products, they were implanted onto silica beads, and the loading rates were quantified.

the energy transfer (ET) between CdSe QDs and phthalocyanines (Pcs) was monitored and evaluated with regard to the functionalization of the axialphthalocyanine ligand, bulkiness of the functional group bridging the QD donor and Pc acceptor, and the number of the functionalized axial ligands. New silicon PCs and their conjugates with CdSe QDs were synthesized. The ET efficiency and kinetics were studied
