The intramolecular heterodimer probe 4-O-dabsyl-2-O-dansyl-myo-inositol-1,3,5-orthoformate undergoes biomimetic reduction of the azo bond in the dabsyl group to give a fluorescence emission band at 560 nm. This is attributed to the loss of energy transfer between the fluorophore (dansyl) and quencher (dabsyl) groups as a result of the formation of 4-O-(4-aminobenzene sulfonyl)-2-O-dansyl-myo-inositol-1,3,5-orthoformate.

甲酸酯经历
生物仿生的偶氮键还原,产生560 nm的荧光发射带。这被归因于由于形成4-O-(4-
氨基苯磺酰)-2-O-dansyl-myo-inositol-1,3,5-正式
甲酸酯,导致荧光体(dansyl)与淬灭体(dabsyl)之间的能量传递损失。
