Substitution of F-Bodipy with alkynylaryl residues at boron, at the pyrrolic core or at the meso position, provides unique tri-, tetra-, and pentasubstituted dyes. Substitution at the (pyrrolic) 2,6-positions provides substantial red shifts with quantum yields in the 40-90% range and excited-state lifetimes of 3-7 ns. ON/OFF fluorescence switching can be produced by protonation of dibutylamino subunits.
在硼原子、吡咯核心或中位用炔基芳基残基取代氟硼二吡咯,可得到独特的三取代、四取代和五取代染料。在(吡咯的)2,6-位进行取代会产生显著的红移,量子产率在40 - 90%范围内,激发态寿命为3 - 7纳秒。二丁基氨基亚基的质子化可实现荧光的开/关切换。
