超稳定的三(二烷基氨基)-氮杂二氧三三角碳鎓离子(A-ADOTA(+)) 4 已被合成并表征。由于平面三角系统中正电荷的扩展离域以及多个强给电子基团的存在，A-ATOTA(+) 离子表现出极高的阳离子稳定性，pK(R+) 值接近 25。此外，A-ATOTA+ 离子表现出优异的染料性能，在 458 nm 处具有强吸收和高荧光量子产率。
The super stabilized tris(dialkylamino)-azadioxatriangulenium carbenium ion (A-ADOTA(+)) 4 has been synthesized and characterized. As a result of extended delocalization of the positive charge in the planar triangulenium system and the presence of several strongly electron-donating groups, the A-ATOTA(+) ion displays extreme cation stability with a pK(R+) value close to 25. Furthermore the A-ATOTA+ ion shows excellent dye properties with intense absorption at 458 nm and high fluorescence quantum yield.
