Highly thermo‐ and photostable, near‐infrared‐absorbing heptamethine cyanine dyes were achieved with the use of fluorine‐containing components. In particular, one prepared heptamethine cyanine dye, bearing a tetrakis(pentafluorophenyl)borate as a counter anion and an N ‐ethyl‐2,2,2‐trifluoroacetamido group at the meso position, showed not only a high decomposition temperature ( T dt ), but also very high photostability toward white LED irradiation.
