| 英文摘要 | A near-infrared (NIR) fluorescent "turn-on" probe is presented for dissolved carbon dioxide (dCO(2)) detection in aqueous medium. This probe is based on perylene bisimide-functionalized hyperbranched polyethylenimine (PBI-HPEI) polymer, which exhibits typical NIR fluorescence due to the excimer emission of pi-pi stacked PBI fluorophores. Both UV-vis absorption and fluorescent spectroscopy studies reveal that the PBI-HPEI polymer shows significantly dCO(2)-sensitive NIR emission via a known photoinduced electron transfer (PET) mechanism. Importantly, this sensory system is characterized with facile synthesis, fast response, excellent water-solubility and wide linear detection concentration range. It is thus capable of detecting dCO2 even in real-world carbonated beverages and drinking water samples. Additionally, in view of the modular design principle of the present fluorescent polymer with typical NIR excimer emission of pi-pi stacked PBI molecules, the proposed strategy is expected to be applicable to the fabrication of novel versatile NIR-emitting sensory materials.
