A phosphole compound represented by the formula
(wherein Ar
1
and Ar
2
are the same or different, and represent an optionally substituted aromatic hydrocarbon ring or an optionally substituted heteroaromatic ring; Ar
3
represents a divalent π-conjugated unit; R
1
represents an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted aryl group, or an optionally substituted heteroaryl group; R
2
and R
3
are the same or different, and represent a hydrogen atom, an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted aryl group, or an optionally substituted heteroaryl group; and Z represents a reactive group) can provide a fluorescent dye capable of maintaining a high fluorescence quantum yield irrespective of solvent polarity, and providing an improved fluorescence quantum yield and light resistance even in environments containing large amounts of water.
一个由以下公式表示的磷杂环化合物
(其中Ar1和Ar2相同或不同,表示一个可选择取代的芳香烃环或一个可选择取代的杂环烃环;Ar3表示一个二价π-共轭单元;R1表示一个可选择取代的烷基团、一个可选择取代的环烷基团、一个可选择取代的芳基团或一个可选择取代的杂芳基团;R2和R3相同或不同,表示一个氢原子、一个可选择取代的烷基团、一个可选择取代的环烷基团、一个可选择取代的芳基团或一个可选择取代的杂芳基团;Z表示一个反应性基团)可以提供一种荧光染料,能够保持高荧光量子产率,不受溶剂极性影响,并且在含有大量水的环境中也能提供改善的荧光量子产率和耐光性。
