Abstract: A compound represented by the formula (I) (R1 represents hydrogen atom or a monovalent substituent; R2 and R3 represent hydrogen atom, an alkyl group, or a halogen atom; R4 and R5 represent an alkyl group or an aryl group; R6 and R7 represent hydrogen atom, an alkyl group, or a halogen atom; R8 represent hydroxy group or a dialkoxyboranetriyl group; and X represents silicon atom, germanium atom, or tin atom), which is a novel fluorophore usable as a mother nucleus of an off/on type fluorescent probe not utilizing the intramolecular photoinduced electron transfer.
