| 摘 要： | 本文研究了6种长链菁染料薄膜的光谱特性与光稳定性,以及两种抗氧剂对其薄膜光稳定性的影响。研究表明,结构相近的菁染料利用旋涂法成膜后,光稳定性与其母核的结构有关,依吲哚>喹啉> 唑>噻唑>硒唑顺序而变,与溶液状态下相类似,两种抗氧剂均为有效的单重态氧猝灭剂,都能提高菁染料的光稳定性。且抗氧剂的用量对染料的稳定性也会产生一定的影响

| Abstract: | Six different kinds of near infrared absorbing cyanine dye with typical structure in spin coated film have been chosen for studying their spectroscopic properties and the relationship berween structure and stability. Results show that cyanine dye film has much wider absorbing range than the same dye in solution. It has also been found that indolenine series dye exhibit markedly higher stability than other kinds of cyanine dye, and the structure of cyanine dye can greatly affected its photostability. We have succeeded in stabilizing cyanine dye film with two different singlet-oxygen quenchers to an acceptable level. At the same time, it has been indicated that the content of quencher is also an important factor that affects the photostability of dye. |
