Merocyanines are a class of fluorescent dyes typified by merocyanine I.

These dyes are usually intensely colored and have large extinction coefficients.

Merocyanine 540 was the first fluorescent dye used for measuring membrane potential,[1] while Brooker's merocyanine and related compounds are notable for their solvatochromatic properties.

Merocyanine 540 differs from merocyanine I by the replacement of an oxygen atom with a sulfur atom
