新型光稳定剂——嘌呤类似物的合成及表征

Synthesis and Characterization of Novel Light Stabilizers——Purine Analogs

以嘌呤类碱基为基本结构单元.通过酰胺化反应引入芳香环.合成出12个熔点高、相对分子质量大的嘌呤类似物。经检测发现,所得的嘌呤类似物在紫外吸收方面性能均有所提高,在光稳定剂领域具有潜在的应用价值。

Using nucleic acid bases of purine as the basic structure, twelve purine analogs are synthesized via introducing aromatic amide, These purine analogs have high melting points and great molecular weights. The UV absorption data indicate that they enhanced UV absorption performance. These purine analogues have potential value in light stabilizer field.
