The present invention relates to a new class of substituted aza-triangulenium fluorescent dyes having a hydroxy group attached to an aryl as quenching group. The new substituted aza-triangulenium fluorescent dyes may be attached to a linker, conjugated to carrier molecule such as e.g. a protein, a nucleic acid, a lipid, or a saccharide, or deposited or immobilised on solid support materials. The substituted aza-triangulenium fluorescent dyes are useful for various purposes, including use in sensors for monitoring or determining the concentration of analytes, such as H+(pH), Na+, K+, Ca2+, O2, CO2, H2O2, ionic strength, redox potentials, metal ions,and metabolites.
