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 (Tdt ), but also very high photostability toward white LED irradiation.
通过使用含氟组分，获得了具有高热稳定性和光稳定性的近红外吸收七甲川花菁染料。特别地，制备的一种七甲川花菁染料，其带有四（五氟苯基）硼酸盐作为抗衡阴离子，并且在中位带有N-乙基-2,2,2-三氟乙酰胺基，不仅具有高分解温度（Tdt），而且对白色LED照射具有非常高的光稳定性。
