A new route is developed to control the self-assembly of gold nanoparticles (AuNPs) functionalized with a novel pyridyl-ended porphyrin-oligo(p-phenylene vinylene) conjugated oligomer (P-OPV-Py) into branched-rods, chain-networks, uniform fractal-like Au clusters, and larger nanoparticles. The techniques of optical spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering (DLS) are used to characterize the self-assembly in various solvent systems (pure toluene, CHCl(3)/toluene, THF/toluene and n-butanol/toluene). A combination of the ligand/AuNPs molar ratio and relative concentration serves as the driving force to control the size and shape of P-OPV-Py capped AuNPs.
开发了一条新途径，以控制用新型吡啶基卟啉 - 聚对苯撑乙烯共轭低聚物（P-OPV-Py）功能化的金纳米颗粒（AuNP）自组装成支链棒、链状网络、均匀的类分形金簇和更大的纳米颗粒。利用光谱学、透射电子显微镜（TEM）和动态光散射（DLS）技术对各种溶剂体系（纯甲苯、CHCl₃/甲苯、THF/甲苯和正丁醇/甲苯）中的自组装进行表征。配体/AuNP摩尔比和相对浓度的组合作为控制P-OPV-Py包覆AuNP尺寸和形状的驱动力。
