Patent ID: 10451640

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 R1 and R2 represent lower alkyl; R3 and R4 represent hydrogen; R5 represents hydrogen, hydroxyl, or a group represented by formula (A): —NR51R52 wherein R51 and R52 represent lower alkyl; R6 and R7 represent hydrogen; ring A represents an aromatic ring; V represents O or SiR10R11 wherein R10 and R11 are the same or different and represent, hydrogen or lower alkyl; W represents CH2, 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.
