The present invention provides a sulfonate compound, including a structure represented by a general formula (I) below,
where, in the formula (I), an atomic group A-O is an atomic group that forms a fluorescent compound upon cleavage of a covalent bond between the atomic group A-O and a sulfonyl group,
one or a plurality of atomic groups B-SO3- are bonded to an atomic group A,
B is a ring that is substituted by one or a plurality of electron-withdrawing groups,
the electron-withdrawing group is at least one selected from the group consisting of an alkyl halide group, a nitro group and a cyano group, and
B may be the same or different in kind in the case where the plurality of B exist.
本发明提供了一种磺酸盐化合物,包括以下通式 (I) 所代表的结构、
其中,在式(I)中,原子团 A-O 是在原子团 A-O 与磺酰基之间的共价键裂解时形成荧光化合物的原子团、
一个或多个原子团 B-SO3- 与原子团 A 键合、
B 是被一个或多个抽电子基团取代的环、
抽电子基团至少选自烷基卤化物基团、硝基基团和氰基基团组成的组,且
在存在多个 B 的情况下,B 的种类可以相同,也可以不同。
