Title:
ケイ素含有複素環式化合物及び消光剤
Document Type and Number:
Japanese Patent JP6919653
Kind Code:
B2
Abstract:
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.)
