Abstract

An Fe(II) ion detection agent, and related method, capable of fluorescently detecting Fe(II) ions quickly with high sensitivity is disclosed. The Fe(II) ion detection agent can be a compound represented by formula (I) (fluorescence probe): wherein Rand Rrepresent lower alkyl; Rand Rrepresent hydrogen; Rrepresents hydrogen, hydroxyl, or a group represented by formula (A): —NRRwherein Rand Rrepresent lower alkyl; Rand Rrepresent hydrogen; ring A represents an aromatic ring; V represents O or SiRRwherein Rand Rare the same or different and represent, hydrogen or lower alkyl; W represents CH, CO; Z represents O; m and n are the same or different and represent 0 or 1. The agent can be combined with a compound having at least three coordinating positions.
