Addition of bis-pyrazole based cryptand regioisomers (1 and 2) to citrate stabilized gold nanoparticles (AuNPs) led to gold supraspheres (AuSSL) and elongated dodecahedron (AuEDL) supraparticles, respectively. These supraparticles as heterogenous hosts show a high uptake of a small fluorophore SEA-SC1 in an aqueous medium and reversible release in organic solvents.
将双吡唑基cryptand 区域异构体(1 和 2)添加到柠檬酸盐稳定的金纳米粒子(AuNPs)中,分别得到金超球(AuSSL)和拉长的十二面体(AuEDL)超粒子。这些超粒子作为异质宿主,在水介质中表现出对小荧光团 SEA-SC1 的高摄取率,并在有机溶剂中可实现可逆释放。
