| 3 | Topological effect on fluorescence emission of tetraphenylethylene-based metallacages显示文摘Herein,we describe the selective formation of a barrel-shaped or a ball-shaped fluorescent metallacage by controlling the shape and stoichiometry of the building blocks.Specifically,the tetraphenylethylene-based donor and two acceptors with different numbers of Pt(Ⅱ)centers were combined via coordination-driven self-assembly.Owing to the differences in the shapes of the assemblies,the resultant ball-shaped metallacage displayed stronger and blue-shifted fluorescence compared to the barrel-shaped one in dilute solutions,while a reversal of fluorescence intensities was observed in the aggregation process.Overall,this work demonstrates that the photophysical properties of supramolecular coordination complexes can be affected by subtle geometrical factors,which can be controlled precisely at the molecular level. | Yuhang Liu Zhewen Guo Yuchen Gu Guangfeng Li Shengbing Yang Xuzhou Yan Yi Shen Jinbing Wang | 2023 | Chinese Chemical Letters2023，34，12： | 0 |
| 4 | Non-specific phospholipase C4 hydrolyzes phosphosphingolipids and phosphoglycerolipids and promotes rapeseed growth and yield显示文摘Phosphorus is a major nutrient vital for plant growth and development,with a substantial amount of cellular phosphorus being used for the biosynthesis of membrane phospholipids.Here,we report that NON-SPECIFIC PHOSPHOLIPASE C4(NPC4)in rapeseed(Brassica napus)releases phosphate from phospholipids to promote growth and seed yield,as plants with altered NPC4 levels showed significant changes in seed production under different phosphate conditions.Clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated nuclease 9(Cas9)-mediated knockout of Bna NPC4 led to elevated accumulation of phospholipids and decreased growth,whereas overexpression(OE)of Bna NPC4resulted in lower phospholipid contents and increased plant growth and seed production.We demonstrate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in vitro,and plants with altered Bna NPC4 function displayed changes in their sphingolipid and glycerolipid contents in roots,with a greater change in glycerolipids than sphingolipids in leaves,particularly under phosphate deficiency conditions.In addition,Bna NPC4-OE plants led to the upregulation of genes involved in lipid metabolism,phosphate release,and phosphate transport and an increase in free inorganic phosphate in leaves.These results indicate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in rapeseed to enhance phosphate release from membrane phospholipids and promote growth and seed production. | Bao Yang Jianwu Li Jiayu Yan Ke Zhang Zhewen Ouyang Yefei Lu Huili Wei Qing Li Xuan Yao Shaoping Lu Yueyun Hong Xuemin Wang Liang Guo | 2023 | Journal of Integrative Plant Biology2023，65，11： | 0 |
| 5 | Conformational effect on fluorescence emission of tetraphenylethylene-based metallacycles显示文摘Herein,we designed and constructed two metallacycles,1 and 2,to illustrate the conformational effect of isomeric AIE fluoropho res on the platfo rm of supramolecular coordination complexe s(SCCs).Specifically,the dangling phenyl rings in TPE units of the metallacycle 1 align completely outside the main cyclic structure,while in the metallacycle 2,these phenyl rings align half inside and half outside.The experimental results showed that two metallacycles exhibited different behaviors in terms of AIE fluorescence and chemical sensing,which could be attributed to the subtle structural difference of the TPE units.This work repre sents the unification of topics such as self-assembly,AIE,and chemical sensing,and further promotes the understanding for the structure-property relationship of isomeric AIE fluorophores. | Zhewen Guo Jun Zhao Yuhang Liu Guangfeng Li Heng Wang Yali Hou Mingming Zhang Xiaopeng Li Xuzhou Yan | 2021 | Chinese Chemical Letters2021，32，5： | 0 |
