Paper Abstract

Analogues of the dipyrromethene-BF2 dye PM567 modified at the 8-position by methacryloyloxymethyl (P1MA), smethacryloyloxypentyl (P5MA), and p-methacryloyloxymethylphenyl (PAr1MA) groups have been copolymerized with methyl methacrylate (MMA), and these solid samples were studied by absorption, fluorescence, and photo-degradation spectroscopy. The absorption cross-section and stimulated emission cross-section spectra are determined. The fluorescence quantum distributions and fluorescence lifetimes are measured. High fluorescence quantum yields, ΦF ≈ 0.9, have been obtained. The photo-degradation of the dyes is studied under cw laser excitation conditions. A high photo-stability was observed.
