We have successfully visualized the surface terminal structure of polymer-metal complex [{Cu(μ-Br)(PPh)}(μ-bpy)] nanocrystals (NCs) using Prussian blue (PB) nanoparticles (NPs). From TEM observation and analysis of the electron beam diffraction pattern, it was found that the (010) plane had grown well, and that the terminal ends of main chains would be located on the (010) plane of the present NCs as a dangling bond. Actually, PB NPs were selectively adsorbed on the (010) plane of [{Cu(μ-Br)(PPh)}(μ-bpy)] NCs. This fact clearly means bipyridine ligands having a nitrogen-terminal located on the surface of the (010) plane would coordinate and bind to Fe ions in PB NPs, which would lead to a new class of polymer-metal complex NCs materials.
我们已成功利用普鲁士蓝（PB）纳米颗粒（NPs）可视化了聚合物 - 金属配合物[{Cu(μ - Br)(PPh)}(μ - bpy)]纳米晶体（NCs）的表面末端结构。通过透射电子显微镜（TEM）观察和电子束衍射图案分析发现，（010）面生长良好，并且主链的末端会作为悬空键位于当前NCs的（010）面上。实际上，PB NPs选择性地吸附在[{Cu(μ - Br)(PPh)}(μ - bpy)] NCs的（010）面上。这一事实清楚地表明，位于（010）面表面且具有氮末端的联吡啶配体将与PB NPs中的铁离子配位并结合，这将导致一类新型的聚合物 - 金属配合物NCs材料。
