我们通过开发已建立的非均相反应工艺，成功制备了不溶性聚合物-金属配合物[{Cu-2(mu-Br)(2)(PPh3)(2)}(mu-bpy)](n) (bpy = 4, 4'-联吡啶)纳米晶，该纳米晶在固态下清晰地发光。通过应用改进的非均相反应工艺，光致变色的偶氮吡啶也被吸附和修饰在聚合物-金属复合物纳米晶的表面上。有趣的是，所获得的偶氮吡啶修饰的聚合物金属配合物纳米晶通过偶氮吡啶在纳米晶表面的交替光异构化而发射光响应荧光。
We have successfully fabricated insoluble polymer-metal complex [{Cu-2(mu-Br)(2)(PPh3)(2)}(mu-bpy)](n) (bpy = 4, 4'-bipyridine) nanocrystals by developing already-established heterogeneous reaction process, which clearly showluminescence in solid state. Photochromic azopyridine was also adsorbed and modified on the surface of polymer-metal complex nanocrystals through applying the improved heterogeneous reaction process. Interestingly, the obtained azopyridine-modified polymermetal complex nanocrystals emitted photoresponsive fluorescence by alternative photoisomerization of azopyridine on the nanocrystals surface.
