7-(dimethylamino)coumarin-3-carboxylic acid is utilized as a laser dye, fluorescent label, and biomedical inhibitor in various applications.

Dansyl fluoride is a fluorogenic reagent used as a specific fluorescent probe for serine proteases and is a serine-type protease inhibitor. It is an active site directed fluorescent inhibitor of guanidinobenzoatase (GB), which binds to both the colonic isoenzymic forms of the GB. The GB on cell surfaces after binding dansyl fluoride makes the cells fluoresce blue. It has been used for the location of tumour cells in frozen sections of human lung squamous cell carcinoma and colonic carcinoma tissues. It is used as a precursor for the synthesis of other derivatives like dansyl amide. Spectral data: λex 360nm; λem 580nm (methanol).

3,3'-Dipropylthiadicarbocyanine iodide is applied for transmembrane potential measurements.

3,3′-Diethyloxadicarbocyanine iodide is a suitable dye for mode-locking both pulsed and cw tunable rhodamine 6G lasers. It has been used as a micellar probe as it is positively charged and it stays at the micelle–water interface.

Squarylium dye (SQ), which is an analogue of cyanine dye, has a squaraine moiety in the center of the π-conjugate. The SQ dye has a zwitterion structure in which the cation and anion coexist in the molecule, although the cyanine dye has a separated cation component. The SQ was conventionally used as a charge generation material for an organic photo conductors. Recently, SQ provided a sensitizer for organic solar cells originating from a strong absorption in near infrared area. In addition, the SQ dye was applied to an organic light-emitting diode because it shows efficient red luminescence.
