Boron dipyrromethene (BDP)-based derivative very bright gas phase fluorescence. Vapours of 3,5-Dimethyl-BDP have fluorescence that can be easily seen by naked eye when excited with a 365 nm LED torch. The bright fluorescence of BDP volatile dyes is a unique property. Gas-phase fluorescence excitation λmax = 494 nm; gas-phase fluorescence emission λmax = 499 nm.
The same property characteristic of gas-fluorescent BDP is also possessed by BDP 505/515 lipid stain (gas-phase λmax(ex) = 492 nm; λmax(em) = 497 nm).
