摘要
光致变色高分子材料近年来得到了研究者的高度关注,一般以接枝、共聚和共混为主要研究对象。文章用对氨基苯甲酸经过重氮化、还原、中和,合成了对羧基苯肼,并进一步合成了N-甲基-5-羧基-9’-羟基螺噁嗪,即SO-1;以及用丙烯酸和氢溴酸合成了3-溴丙酸,代替了传统的3-碘丙酸合成N-羧乙基-9’-羟基螺噁嗪,即SO-2。通过熔点测试和核磁确定了其结构。两种未见文献报道的化合物均含两种官能团,可以进行自身的缩合,也可以接枝上不同的聚合物以获得更优良的光致变色性能。
Researchers have paid high attention to photochromic polymer materials in recent years, and research objects are mainly graft polymer, copolymerization and polymer blend. In this article 4-hydrazinobenzoic acid was synthesized from p-aminobenzoic acid by diazotization, restoration and neutralization. And then N-methyl-5-carboxyl-9-hydroxyl spirooxazine, namely SO-1, were also syn- thesized. Furthermore, 3-bromopropionic acid was synthesized from acrylic acid and hydrobromic acid. N-Carboxy ethyl-9'- hydroxy spirooxazine, namely SO-2, were synthesized from 3-bromopro- pionic acid that was in place of the traditional 3-iodopropionic acid. The structure of SO-2 was proved with melting point test and nuclear magnetism. Two compounds, SO-1 and SO-2, which had not been reported in literature, both contain two kinds of functional groups, can self-condense or graft different polymers to obtain better photochromic properties.
