We report a single step procedure to prepare monodisperse colloidal poly(methyl)methacrylate (PMMA) particles where fluorescent dyes are incorporated into the polymer network. The particles are sterically stabilized against flocculation by poly(12-hydroxystearic acid). The fluorescent dyes are RITC (rhodamine isothiocyanate)-aminostyrene (RAS) and 4-methylaminoethylmethacrylate-7-nitrobenzo-2-oxa-1,3-diazol (NBD-MAEM), which are prepared from (commercially available) RITC and 4-chloro-7-nitrobenzo-2-oxa-1,3-diazol (NBD-Cl), respectively, as starting materials. The particles can be grown larger with nonfluorescent PMMA. Examples of the usefulness of these model particles in colloid science are given.
我们报道了一种制备单分散胶体聚甲基丙烯酸甲酯（PMMA）颗粒的单步方法，其中荧光染料被掺入聚合物网络中。这些颗粒通过聚（12-羟基硬脂酸）实现空间稳定，防止絮凝。荧光染料是异硫氰酸罗丹明（RITC）-氨基苯乙烯（RAS）和甲基丙烯酸4-甲氨基乙酯-7-硝基苯并-2-恶唑-1,3-二氮杂环戊二烯（NBD-MAEM），它们分别由（市售的）RITC和4-氯-7-硝基苯并-2-恶唑-1,3-二氮杂环戊二烯（NBD-Cl）作为起始原料制备。这些颗粒可以与非荧光PMMA一起生长得更大。文中给出了这些模型颗粒在胶体科学中的实用性示例。
