phosphites, sodium dialkyl phosphites, phosphoramidites, phosphinites, and phosphonites to highly polarized or cationic fluorophores, followed by oxidation, results in new “PONy” dyes with auxochromic phosphinate, phosphonate, or phosphonamidate groups. The reaction was applied to a wide variety of coumarins, (thio)pyronins, and N-alkylacridinium and 5,6-dihydrobenzo[c]xanthen-12-ium salts as well as a meso-chlorinated
次膦酸,亚磷酸酯,亚磷酸二烷基酯亚磷酸酯,亚磷酰胺,亚膦酸酯和亚膦酸酯的亲核加成反应到高偏振或阳离子荧光团上,然后进行氧化,产生具有无色亚膦酸酯,亚膦酸酯或膦酰胺基团的新型“ PONy”染料。该反应可用于多种香豆素,(硫代)pyronins,N-烷基ac啶鎓和5,6-二氢苯并[ c ]黄嘌呤-12-盐以及内消旋氯化的BODIPY,以提供致密的染料,并带有红色的改变了吸收带和发射带,斯托克斯位移高达8200 cm –1。
