We aim to grow specific-sized metal and semiconductor nanoparticles inside rigid molecular cages called cucurbiturils, and subsequently assemble them into functional nano-chains. Combining these filled cages with well-defined connector molecules allows us to precisely define particle geometries, particle separations and particle interfacing. This in turn enables the robust construction of plasmonic optical antennae at visible wavelengths, room-temperature single-electron-tunnelling transistors and combined photovoltaics. Such functional properties open up novel alternative methods for directed assembly using irradiation with precisely-tuned lasers, nano-electrochemistry or ac-electric fields. This approach will constitute the basis of a new nanotechnology platform for organic-inorganic ordered nano-composites.

我们的目标是在称为葫芦脲的刚性分子笼内生长特定尺寸的金属和半导体纳米颗粒，然后将它们组装成功能性纳米链。将这些填充笼与定义明确的连接分子相结合，使我们能够精确定义颗粒几何形状，颗粒分离和颗粒界面。这反过来又使得在可见光波长下的等离子体光学天线、室温单电子隧道晶体管和组合光电晶体管的稳健构造成为可能。这种功能特性开辟了新的替代方法，用于使用精确调谐的激光器，纳米电化学或交流电场照射的定向组装。这种方法将构成有机-无机有序纳米复合材料的新的纳米技术平台的基础。
