Abstract: The effect of different metal ions on the photo-stability of complexed azo dyes,formazan dyes and phthalocyanine dyes was reviewed. The metal ions included Co(Ⅲ),Co(Ⅱ),Ni(Ⅱ),Cu(Ⅱ) and were introduced into the structure of dyes. Such metal ions played a key role as the energy absorber from the triplet dye,reduced the quantum yield of triplet dye and improved the photostability of the dyes.

摘要: 综述了不同金属离子对偶氮型、甲臜型和酞菁型3种染料光稳定性的影响。在染料结构中引入Co(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)等金属离子后,由于这些金属离子的最低激发态能量低于染料三重态能量,在染料结构中起到了能量吸收剂的作用,有效猝灭了染料三重态,从而使染料的光稳定性得到明显提高。
