A series of tunable pH-dependent BODIPYdyes were synthesized and further functionalized in a Knoevenagel condensation reaction with various aldehydes. In this fashion, monofunctional dyes containing an alkyne, azide, or carboxylic acid (masked as its methyl ester) as ligation sites as well as asymmetrical bifunctional dyes were obtained, without compromising their pH-dependency. In addition, fluorescence
