The convergent synthesis of inherently highly fluorescent nanocars incorporating 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY)-containing axles and p-carborane wheels is reported. These nanocars are expected to exhibit rolling motion with predetermined patterns over smooth surfaces, depending on their chassis. Their quantum yields of fluorescence (Phi(F) > 0.7) make them excellent candidates for imaging and tracking by single-molecule fluorescence microscopy. An analogue as a stationary control with tert-butyl groups instead of p-carborane wheels was also synthesized.
本文报道了内在高度荧光的纳米车的会聚合成，该纳米车包含含有 4,4-二氟-4-硼-3a,4a-二氮杂-s-茚（BODIPY）的车轴和 p-碳硼烷车轮。这些纳米车有望在光滑表面上按照它们的底盘以预定的模式进行滚动运动。它们的荧光量子产率（Phi(F) > 0.7）使它们成为单分子荧光显微镜成像和跟踪的优秀候选者。还合成了一个类似物作为带有叔丁基而不是 p-碳硼烷车轮的固定对照。
