Title:

FINE FLUORESCENT PARTICLE CONTAINING AIE-ACTIVE COMPOUND

Document Type and Number:

WIPO Patent Application WO/2018/056454

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a fine fluorescent particle which suffers no concentration quenching and has low ecotoxicity. Specifically, the present invention relates to a fine fluorescent particle comprising a network polymer and containing an AIE-active compound, characterized in that the AIE-active compound is, for example, a compound represented by general formula (1). (In formula (1), E is a silicon or germanium atom, R1 and R2 are the same or different and are each a C1-6 hydrocarbon group or an(un)substituted phenyl group, and R3, R4, R5, and R6 are the same or different and are each an (un)substituted phenyl group.)
