Abstract

Various bisindolylmaleimides have fluorescence emission maxima wavelengths longer than 500 nm, large Stokes shifts longer than 200 nm, different fluorescence emission wavelengths at an excitation wavelength of 365 nm, and a long-lasting chemiluminescence. The expansion of the pi-conjugation, the pi-bond electronic structure, and oxidation of the C=C bond at the 2,3-position of the maleimide moiety are crucial for producing these fluorescence and chemiluminescence properties.

摘要

各种双吲哚马来酰亚胺具有大于500 nm的荧光发射最大波长、大于200 nm的大斯托克斯位移、在365 nm激发波长下不同的荧光发射波长以及持久的化学发光。π共轭的扩展、π键电子结构以及马来酰亚胺部分2,3位C = C键的氧化对于产生这些荧光和化学发光性质至关重要。
