Synergy of CO2-response and aggregation induced emission in a small molecule: renewable liquid and solid CO2 chemosensors with high sensitivity and visibility.
Mai Z , Li H , Gao Y , Niu Y , Li Y , de Rooij NF , Umar A , Al-Assiri MS , Wang Y , Zhou G . Mai Z , et al. Analyst. 2020 May 21;145(10):3528-3534. doi: 10.1039/d0an00189a. Epub 2020 Mar 19. Analyst. 2020. PMID: 32190881
A tetraphenylethylene (TPE) derivative (N,N-dimethyl-N'-(4-(1,2,2-triphenylvinyl)phenyl)acetimidamide, TPE-amidine) was designed and synthesized, and used to prepare visible CO(2) chemosensors, TPE-amidine-L (liquid) and TPE-amidine-S (solid). The hydrophilicity of TPE-ami …

Assembly with copper(ii) ions and D-π-A molecules on a graphene surface for ultra-fast acetic acid sensing at room temperature.
Gong Y, Li H, Pei W, Fan J, Umar A, Al-Assiri MS, Wang Y, Frans de Rooij N, Zhou G. Gong Y, et al. RSC Adv. 2019 Sep 25;9(52):30432-30438. doi: 10.1039/c9ra05706d. eCollection 2019 Sep 23. RSC Adv. 2019. PMID: 35530241 Free PMC article.
Compared with the typical acetic acid gas sensors reported in the literature, it is noteworthy to mention that the as-prepared 4HQ-rGO/Cu(2+) supramolecular assembly exhibited the shortest gas response time (within 5 s) at room temperature. The presented study demonstrates …
