This study explores the synthesis and characterization of two novel antibacterial dendritic methacrylate-based dental monomers. For this purpose, two dendritic esters have been synthesized via condensation reaction and then reacted with methacryloyl chloride to afford methacrylate-end caped dendritic esters. These compounds are subsequently converted to quaternary ammonium fluoride monomers (QAFMs) with decyl substituted side chain to produce two novel antibacterial dendreticdental monomers. The chemical structures of synthesized samples have been characterized using Fourier transform infrared (FTIR) and proton nuclear magnetic resonance (¹H NMR) spectroscopies.The obtained monomers can be used to replace 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropyl)-phenyl]propane (Bis-GMA) as the base monomer of universal resin-based dental composites in the presence of a diluting monomer (e.g.,triethyleneglycoldimethacrylate; TEGDMA), mainly due to their superior characteristics such as multifunctionalities as well as antibacterial activities.

两种新型抗菌树枝状甲基丙烯酸酯类牙科单体的合成与表征

这项研究探索了两种新型的抗菌性基于树枝状甲基丙烯酸甲酯的牙科单体的合成和表征。为此，已经通过缩合反应合成了两种树状酯，然后与甲基丙烯酰氯反应得到甲基丙烯酸酯封端的树状酯。随后将这些化合物转化为带有癸基取代的侧链的氟代季铵盐单体（QAFM），以产生两种新型的抗菌牙本质单体。合成样品的化学结构已使用傅立叶变换红外（FTIR）和质子核磁共振进行了表征（¹所获得的单体可以代替2,2-双[4-（2-羟基-3-甲基丙烯酰氧基丙基）-苯基]丙烷（Bis-GMA）作为通用树脂基牙科复合材料的基础单体主要是由于它们的优越特性（例如多功能性和抗菌活性）而存在于稀释单体（例如，三亚乙基甘油二甲基丙烯酸甲酯； TEGDMA）中。
