摘要
BODIPY类染料以其光化学稳定性好、激光转换效率高、较大的激光发射和可调范围、溶解度好、激发态吸收截面小、三重态驰豫效率小等优点极大提升了光响应能力。在液体、固体聚合物介质中,BODIPY染料在泵浦脉冲下可以产生稳定的激光信号。通过染料分子结构和光物理性质研究,可以筛选出产生最优激光性能的结构和基质。主要介绍了染料共掺及改性聚合物基质固体染料激光的研究进展,同时对新型BODIPY类激光染料的研究现状进行了综述。
Boron dipyrromethenes （BODIPYs） has received great attention because of their versatility,chemical robustness,low triplet state population,thermal and photochemical stability,which enhance the photoresponse of these dyes.For instance,highly efficient lasing signals after multitude of pumping pulses can be achieved when the BODIPY dyes are incorporated in solvents and polymers matrices.The molecular structure and the photophysical properties of BODIPY dyes are studied to obtain the best structural and environmental conditions for the optimal laser performance.In this paper,the lasing properties of BODIPY dyes in solvents and polymers conditions are summarized.The development of new molecular structures based on the BODIPY chromophore is reviewed as well.
