    Preparation and Spectroscopic Properties of Polyglycidyl Methacrylate Bonding Zinc Phthalocyanine on Side Chains

    • 摘要: 首先通过开环反应,将2, 9, 16, 23-四氨基取代的锌酞菁(ZnTAPc)键合在聚甲基丙烯酸缩水甘油酯(PGMA)的侧基上,制得键合有氨基锌酞菁(ZnAPc)的聚合物ZnAPc-PGMA。然后使ZnAPc-PGMA侧基上的氨基与对二甲氨基苯甲醛(DMAB)发生席夫碱反应,制得侧基含芳环席夫碱基团的锌酞菁(ZnABPc)的聚合物ZnABPc-PGMA。通过测定氨基锌酞菁在PGMA上的键合度,重点研究了反应时间、温度和催化剂种类对ZnTAPc在PGMA上键合过程的影响。测定了ZnAPc-PGMA和ZnABPc-PGMA的紫外-可见吸收光谱及荧光发射光谱,考察了其光物理学行为。结果表明,所制备的ZnAPc-PGMA和ZnABPc-PGMA均具有ZnTAPc的特征电子吸收光谱与荧光发射光谱,同时也显示出锌酞菁键合到聚合物上的特征。ZnTAPc键合到PGMA上后,有效地减弱了其聚集性。此外,随着ZnAPc在PGMA上键合度的增大,荧光吸收光谱强度增强。同时,ZnAPc-PGMA的荧光光谱还显现了一定的高分子效应,随着ZnAPc-PGMA中ZnAPc键合度的增大,ZnAPc侧链单元间会发生能量转移,使荧光发射强度减弱。

       

      Abstract: Tetra amino zinc phthalocyanine (ZnTAPc) was bonded on the side chains of polyglycidyl methacrylate (PGMA) through the ring opening reaction between the amino groups of ZnTAPc and the epoxy groups of PNMA, (denoted as ZnAPc-PGMA). Subsequently, Schiff base reaction between ZnAPc-PGMA and dimethylamino-benzaldehyde (DMAB) was carried out to prepare PGMA bonded with the aromatic Schiff base-contained zinc phthalocyanine (denoted as ZnABPc-PGMA). The effects of the kinds of catalysts and temperature on the bonding process of ZnTAPc on PGMA were investigated by the determination of bonding degree of ZnAPc on PGMA. Their UV-Visible absorption spectra and fluorescence emission spectra were determined, and their photophysical behavior was examined. Results show that ZnAPc-PGMA and ZnABPc-PGMA possess the characteristic electronic absorption and fluorescence emission spectra of zinc phthalocyanine. In addition, they still present some other characters. As ZnTAPc is bonded to PGMA, its aggregability is weakened effectively. And the intensity of the absorption spectra of ZnAPc-PGMA increases with the increasing bonding amount of ZnAPc on the side chains of polymer PGMA. However, ZnAPc-PGMA exhibits a polymer effect in its photophysical behavior. As the concentration of ZnAPc units in ZnAPc-PGMA solution increase, the energy transfer between the adjacent side ZnAPc units will be produced, resulting in the slight weakening of the fluorescence emission.
