在硼、吡咯核或内消旋位置用炔基芳基残基取代F-Bodipy提供独特的三取代、四取代和五取代染料。在（吡咯）2，6-位的取代提供了大量的红移，量子产率在40-90%范围内，激发态寿命为3-7 ns。ON/OFF荧光切换可以通过二丁基氨基亚基的质子化来产生。
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.
