Quenchers of the related art do not have a quenching ability high enough to sufficiently inhibit the emission of fluorescence from fluorescence compounds. Therefore, the present invention aims to provide a quencher which can sufficiently quench the fluorescence from fluorescent compounds including xanthene-based dyes. The present invention relates to a quencher formed of a compound represented by the following general formula (1), and the like.
(In the formula, n
1
pieces of R
5
each independently represent a group having a polymerizable unsaturated group, an amino group having a substituent, or the like, R
6
represents a group having a polymerizable unsaturated group, a hydroxy group, or the like, An
−
represents an anion, Ar
1
represents a specific ring structure, * and ** each represent a position of bonding to the specific ring structure, Ar
2
represents a benzene ring or the like, in a case where Ar
2
is the benzene ring, n
1
represents an integer of 0 to 4, and R
32
and R
33
each independently represent an alkyl group or an aryl group.)
相关艺术中的淬火剂没有足够高的淬火能力,以充分抑制荧光化合物的荧光发射。因此,本发明旨在提供一种可以充分淬火包括
黄酮基
染料在内的荧光化合物的荧光的淬火剂。本发明涉及由以下一般式(1)所代表的化合物形成的淬火剂等。(在该式中,n1个R5分别独立地表示具有聚合不饱和基团、具有取代基的
氨基团等的基团,R6表示具有聚合不饱和基团、羟基等的基团,An−表示一个阴离子,Ar1表示特定的环结构,*和**分别表示与特定环结构结合的位置,Ar2表示苯环或类似物,在Ar2为苯环的情况下,n1表示0到4的整数,
R32和R33分别独立地表示烷基或芳基。)
