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, n1 pieces of R5 each independently represent a group having a polymerizable unsaturated group, an amino group having a substituent, or the like, R6 represents a group having a polymerizable unsaturated group, a hydroxy group, or the like, An− represents an anion, Ar1 represents a specific ring structure, * and ** each represent a position of bonding to the specific ring structure, Ar2 represents a benzene ring or the like, in a case where Ar2 is the benzene ring, n1 represents an integer of 0 to 4, and R32 and R33 each independently represent an alkyl group or an aryl group.).
相关技术中的淬灭剂的淬灭能力不足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淬灭剂,它能够充分淬灭包括呫吨基染料在内的荧光化合物的荧光。本发明涉及一种由以下通式(1)所代表的化合物等组成的淬灭剂。
(式中,n1片段的R5各自独立地代表具有可聚合的不饱和基团、具有取代基的氨基等的基团,R6代表具有可聚合的不饱和基团、羟基等的基团,An-代表阴离子、Ar1 代表特定的环结构,* 和 ** 分别代表与特定环结构键合的位置,Ar2 代表苯环或类似物,在 Ar2 为苯环的情况下,n1 代表 0 至 4 的整数,R32 和 R33 分别独立地代表烷基或芳基。).
