Abstract

Self-assembled nanoparticles have important applications in energy systems, optical devices and sensors, via the formation of aggregates with controlled interparticle spacing. Here we report aqueous self-assembly of rigid macrocycle cucurbit[7]uril (CB[7]) and fluorescent quantum dots (QDs), and demonstrate the potential of the system for efficient energy transfer and sensing of small molecules.

摘要

通过形成具有可控颗粒间间距的聚集体，自组装纳米颗粒在能源系统、光学器件和传感器中具有重要应用。在此，我们报道了刚性大环葫芦[7]脲（CB[7]）和荧光量子点（QDs）在水中的自组装，并证明了该系统在高效能量转移和小分子传感方面的潜力。
