A strategy is reported for the controlled assembly of organic-inorganic heterostructures consisting of individual single-walled carbon nanotubes (SWCNTs) selectively coupled to single semiconductor quantum dots (QDs). The assembly in aqueous solution was controlled towards the formation of monofunctionalized SWCNT-QD structures. Photoluminescence studies in solution, and on surfaces at the single nanohybrid level, showed evidence of electronic coupling between the two nanostructures. The ability to covalently couple heterostructures with single particle control is crucial for the design of novel QD-based optoelectronic and light-energy conversion devices.
本文报道了一种策略，用于控制组装由单个单壁碳纳米管（SWCNTs）选择性偶联到单个半导体量子点（QDs）组成的有机-无机杂化结构。在水溶液中进行组装，以形成单官能化的 SWCNT-QD 结构。在溶液中和在单纳米杂化物水平的表面上的光致发光研究表明，两种纳米结构之间存在电子耦合的证据。用单粒子控制共价偶联杂化结构的能力对于设计新型基于 QD 的光电和光能量转换器件至关重要。
