Weakly fluorescing (øF ⋍ 10−4, hexane) dipyrrinone analogs of bilirubin, methyl xanthobilirubinate and kryptopyrromethenone, exhibit intense room temperature fluorescence (øF ⋍ 0.85, cyclohexane) after conversion to their N10–N11 methano-bridged derivatives 1 and 2.
弱荧光(ø ˚F ⋍10 -4,己烷)胆红素,甲基xanthobilirubinate和kryptopyrromethenone的dipyrrinone类似物,表现出强烈的室温荧光(ø ˚F ⋍0.85,环己烷)转化成其N之后10 -N 11甲基-桥接的衍生物1和2。
