The stable, water-soluble, and fluorescent sub 1 nm sized poly(acrylic acid)-capped copper nanoparticles (PAACC NPs) were synthesized using a high-intensity ultrasound sonication (30 KHz) method. The reduction of copper NPs from copper(II) salt by mild reducing agent l-ascorbic acid in an aqueous medium was achieved in the presence of poly(acrylic acid). The PAACC NPs were characterized by DRS UV-visible, XPS, PL, FESEM, and HRTEM techniques. The resulting PAACC NPs show orange fluorescence with a peaking center at 560 nm. The PAACC NPs serve as effective catalysts for the synthesis of 1,2,3-triazoles via click reaction in good yields under mild reaction conditions.
采用高强度超声（30kHz）法合成了尺寸小于1nm的稳定、水溶性且具有荧光的聚丙烯酸包覆铜纳米颗粒（PAACC NPs）。在聚丙烯酸存在下，通过温和还原剂L-抗坏血酸在水介质中由铜（II）盐还原得到铜纳米颗粒。通过DRS紫外可见光谱、XPS、PL、FESEM和HRTEM技术对PAACC NPs进行了表征。所得的PAACC NPs呈现橙色荧光，峰值中心在560nm。PAACC NPs在温和反应条件下通过点击反应可有效催化合成1,2,3-三唑，产率良好。
