A Highly Selective Fluorescent Sensor for Distinguishing Cadmium from Zinc Ions Based on a Quinoline Platform
TL;DR: A fluorescent sensor, N-(quinolin-8-yl)-2-yloxy)acetamide (HL), based on 8-aminoquinoline and 8-hydroxyquinoline platforms has been synthesized and displays high selectivity and sensitive fluorescence enhancement to Cd(2+) in ethanol.
Journal ArticleDOI
A coumarin-based two-photon probe for hydrogen peroxide.
Kaiming Zhang,Wei Dou,Pengxuan Li,Rong Shen,Jiaxi Ru,Wei Liu,Yumei Cui,Chunyang Chen,Weisheng Liu,Decheng Bai +9 more
TL;DR: A new fluorescence probe was developed for hydrogen peroxide detection based on donor-excited photo induced electron transfer (D-PET) mechanism, together with the benzil as a quenching and recognizing moiety, and it exhibited high selectivity toward H2O2 over other reactive oxygen species and high sensitivity with a detection limit of 0.09 μM.
Journal ArticleDOI
A highly fluorescent chemosensor for Zn2+ and the recognition research on distinguishing Zn2+ from Cd2+
Pengxuan Li,Xiaoyan Zhou,Ruoying Huang,Lizi Yang,Xiaoliang Tang,Wei Dou,Qianqian Zhao,Weisheng Liu +7 more
TL;DR: A new fluorescent sensor, 2-(2-oxo-2-(quinolin-8-ylamino)ethoxy)-N-(pyridine-2-ylmethyl) benzamide (L), composed of a quinoline group as the fluorogenic unit and a pyridin- 2-ylmethanamine as the binding unit for metal ions has been synthesized and shows excellent selectivity and sensitivity.
Journal ArticleDOI
Diverse lanthanide coordination polymers tuned by the flexibility of ligands and the lanthanide contraction effect: syntheses, structures and luminescence.
Xiaoyan Zhou,Yan-Ling Guo,Zhaohua Shi,Xue-Qin Song,Xiaoliang Tang,Xiong Hu,Zhentong Zhu,Pengxuan Li,Weisheng Liu +8 more
TL;DR: Two new flexible exo-bidentate ligands were designed and synthesized, incorporating different backbone chain lengths bearing two salicylamide arms, which are used as building blocks for constructing diverse lanthanide polymers with luminescent properties.
