摘要：

For two meso-substituted benzo-fused pyrromethenes (BPMM and F-BPMM), photophysical and lasing properties in liquids and in poly(methyl methacrylate) (PMMA) are reported. Both dyes exhibit high quantum efficiency (0.6-0.9) along with high extinction coefficients, values which are superior to other NIR dyes such as oxazine 1 and rhodamine 800. Lasing efficiencies in the range of 20-30 % have been recorded for the new dyes. Additionally, the dyes can be pumped by a diode or dye laser emitting at 650 nm. Under continuous UV-Vis irradiation, BPMM and F-BPMM demonstrated improved photostability as compared with a previously reported analog, PM-700 (Scheme 1). The survivability of dyes under conditions of radical polymerization has also been investigated.
