A new dialdehyde was designed and synthesized containing naphthalene groups, and then its macrocycle was prepared with 1,4-diaminobuthan. A modified nanoprecipitation method has been reported for the preparation of the nanoparticles. In this method, to obtain nanoparticles with small particle sizes, the nucleation rate was increased with decreasing of the mixing time. The organic nanoparticles were
设计并合成了一个新的含萘基的二醛,然后用1,4-二氨基丁烷制备了其大环。已经报道了用于制备纳米颗粒的改进的纳米沉淀方法。在该方法中,为了获得小粒径的纳米颗粒,成核速率随着混合时间的减少而增加。有机纳米粒子用于关闭低浓度的Sn 2+离子对Cs +,K +,Na +,Ba 2 +,Ca 2 +,Mg 2 +,Al 3+,Pb 2等阳离子的荧光响应。+, Zn 2 +,Cu 2 +,Ni缓冲水溶液中的2 +,Co 2 +,Fe 2 +,Mn 2 +,Ag +,Cd 2+和Hg 2+和离子。检测限为5.4 nM。
