A series of novel highly water-soluble neutral BODIPY dyes have been obtained by functionalization of BODIPY dyes with branched oligo(ethylene glycol)methyl ether groups at positions 8, 2 and 6 or 4 and 4'. Use of an ortho-substituent group of branched oligo(ethylene glycol)methyl ether on the meso-phenyl ring of BODIPY dyes and replacement of the fluorine atoms of BODIPY dyes at positions 4 and 4' with methyloxy or ethynyl subunits significantly enhance fluorescence quantum yields of BODIPY dyes.
一系列新型高度水溶性中性 BODIPY 染料已通过在 BODIPY 染料的 8、2 和 6 位或 4 和 4'位用支化聚(乙二醇)甲醚基团官能化而获得。在 BODIPY 染料的间苯环上使用支化聚(乙二醇)甲醚的邻位取代基和用甲氧基或乙炔基取代 BODIPY 染料的 4 和 4'位的氟原子,显著提高了 BODIPY 染料的荧光量子产率。
