The preparation of pH-switchable fluorescent borylated arylisoquinoline dyes via a flexible iridium-catalyzed route is reported. The obtained dyes feature aromatic amino substitution and lateral aliphatic amino groups as electron donors. The photophysical properties of the internal charge transfer dyes were studied, which was complemented by density functional theory calculations. Appreciable fluorescence
报道了通过柔性铱催化的路线制备pH可转换的荧光硼化的芳基异喹啉染料。所获得的染料具有芳族氨基取代基和侧脂族氨基基团作为电子供体。研究了内部电荷转移染料的光物理性质,并辅以密度泛函理论计算。可感知的荧光量子产率(Φ ˚F高达约0.4),并在绿色到红色发射范围特征光谱指纹进行观察。研究了三氟甲磺酸在多重和正交质子化过程中的荧光调制,并导致了对多级转换的解释,包括关-开-关,三元和四元响应。
