initial design. The desired fluorescent probes were synthesized by two different routes in considerable yields. Twenty‐two phthalazinone derivatives were synthesized and their photophysical properties were measured. Selected compounds were applied in cell imaging, and valuable information was obtained. Furthermore, the designed compounds showed excellent performance in two‐photon microscopic imaging of
酞嗪酮衍生物被设计为用于单光子和双光子荧光显微镜成像的光学探针。设计策略包括逐步扩展和修饰哒嗪酮,方法是:1)哒嗪酮扩展为酞菁酮,这是一个较大的共轭体系,作为电子受体; 2)给电子芳族基团(如N,N-二乙基氨基苯基,噻吩基,萘基)的偶联, 3)将烷基链锚定在具有各种末端取代基的酞菁酮上,例如三苯基膦酰基,吗啉代,三乙基铵基,N-甲基咪唑,吡咯烷和哌啶子基。理论计算被用来验证初始设计。通过两种不同的途径以可观的产率合成了所需的荧光探针。合成了22种酞嗪酮衍生物,并对其光物理性质进行了测量。选定的化合物应用于细胞成像,并获得了有价值的信息。此外,设计的化合物在小鼠脑切片的双光子显微成像中显示出优异的性能。
