摘要

利用红外方碱染料的 H-聚合体来检测溶剂中的 Cu2+。与单体相比，H-聚集体是一种具有更强光物理特性的聚集体。在 Ca2+ 溶液中，F-Cl 具有优异的 H-聚集体，加入 Cu2+ 后可转化为单体。此外，这种模式还成功证明了加入 Ca2+ 或 Cu2+ 后体外培养的 HeLa 细胞的荧光变化。利用这种转化模式实现了对 Cu2+ 的高度特异性检测。

H-Aggregation of Squaraine Dye as Generic Colorimetric Molecules to Detect Cu².

An infrared squaraine dye was utilized to detect Cu²⁺ in solvents based on H-aggregates of squaraine dye. H-aggregates are a type of aggregation with enhanced photophysical properties compared to monomers. In the presence of a Ca²⁺ solution, F-Cl offers exceptional H-aggregators that can be transformed into monomers by adding Cu²⁺. Furthermore, this mode successfully demonstrated fluorescence changes in HeLa cells cultured in vitro after the addition of Ca²⁺ or Cu²⁺. A highly specific detection of Cu²⁺ was achieved using this transformation mode.
