超分子聚芴醇能够组装成共轭聚合物纳米颗粒 (CPN)。通过再沉淀制备聚{9-[4-(辛氧基)苯基]芴-9-醇-2,7-二基}(PPFOH)基超分子纳米颗粒。在DMF溶液中加入不同量的水，得到直径为40~200 nm的PPFOH纳米颗粒。在基于 PPFOH 的氢键纳米粒子中观察到与聚（9,9-二辛基芴）不同的尺寸依赖性发光。最后，使用尺寸为80 nm的CPN的白光发射器件呈现出CIE坐标（0.31，0.34）的白光发射。两亲性共轭聚合物纳米粒子是用于制造印刷电子有机器件的潜在有机纳米油墨。
Supramolecular polyfluorenol enable assembly into conjugated polymer nanoparticles (CPNs). Poly{9-[4-(octyloxy)phenyl]fluoren-9-ol-2,7-diyl} (PPFOH)-based supramolecular nanoparticles are prepared via reprecipitation. PPFOH nanoparticles with diameters ranging from 40 to 200 nm are obtained by adding different amounts of water into DMF solution. Size-dependent luminescence is observed in PPFOH-based hydrogen-bonded nanoparticles that is different from that of poly(9,9-dioctylfluorenes). Finally, white light-emitting devices using CPNs with a size of 80 nm exhibit white emission with the CIE coordinates (0.31, 0.34). Amphiphilic conjugated polymer nanoparticles are potential organic nano-inks for the fabrication of organic devices in printed electronics.
