Abstract:Assemblies of quantum-confined semiconductor nanoparticles into block copolymer micelles and silica shell open the door to “tunable” optical, electrical, and even mechanical properties. Sharp tuning of 3D spherical morphology in water solution is a fascinating target owing to favourable optical properties in biological delivery. Here we reported that spherical assemblies of blue-emitting CdSe nanoclusters into CTAB-Micelles, namely CdSe-doped micelles, were well-dispersed in water for a few weeks and revealed a blue emission at 480 nm. Furthermore, the CdSe-doped nanoclusters were self-arranged along the copper phenanthroline-based polymeric chains (1DOP-Cu) to give rise to one-dimensionally redox-specific heterostructures that show fluorescence resonance energy transfer (FRET) process from CdSe Qdots (480 nm) to 1DOP-Cu (364 nm) superstructure. This fascicle technology opens up a new avenue for assemblies of inorganic nanoparticles in 1D nanoparterning structure, which is indispensable for photocatalysts and homogenous assays of phototoxic drugs.
