若干红外激光染料的分子结构与光化学性能

Study on Molecular Structure and Photochemistry of Some Infrared Laser Dyes

对十五种红外激光染料进行了吸收光谱和光稳定性的测试。研究了染料结构与其光谱吸收的关系。确证了染料经过刚性化，能大大提高其光学稳定性。

Absorption spectrum and photostability are inverestigated for a series of heptamethine IR dyes and related to chemical structure.The high photostability of several dyesmake them very interesting for IR dye lasers. It is confirmed that dyes of rigidized structurehave high photostability.
