variation of photophysical properties with a simple alteration of the chemical structure of the phenothiazine framework by terminal groups. The toxicity of the compounds that were obtained was evaluated on cancer as well as normal fibroblast cell lines. The applicatory potential of those phenothiazines as cellular probes have been also evaluated.
一系列乙炔的Ñ -octylphenothiazine醛(PTZ1-PTZ4),用不同的电子终端的能力的取代基(p -甲氧基苯基,p氟苯基,p合成并充分表征了作为A /D-π-DA体系的-三氟甲基苯基和2,5-双(三氟甲基)苯基。这些末端基团对它们的光物理,热学和生物学特性的影响已被彻底检查,并面临理论计算的挑战。新型化合物在高达238–318°C的温度下具有很高的热稳定性。在氯仿溶液中,化合物在约399 nm处显示出分子内电荷转移(ICT)吸收带,并在535 nm处显示出发射带,量子产率在40%至63%之间。从己烷到DMSO的所有溶剂极性范围内,所有化合物均显示出正溶剂溶变色,而在甲醇溶液中,与具有显着荧光猝灭作用的DMSO相比,它们显示出最大发射光的变色现象。PTZ1–PTZ4化合物在488-542 nm的蓝色到黄色区域具有显着的发射,高量子产率为24-91%,在不同极性的溶剂中的寿命为6
