| 1 | Controlled Step-Growth Polymerization显示文摘Conjugated polymers are attractive components of modern plastic electronics and photovoltaic devices.They are synthesized mainly through a step-growth polymerization(SGP)mechanism.However,due to the uncontrollable characteristic of classical SGP,this effort leads to batch-to-batch variations in solubility,uncontrolled molecular weight,and broad polydispersity of the polymers obtained,thus,severely limiting their processing properties and performance.Here we demonstrate a general theoretical model of controlled SGP process by examining the possibility of the polymer chains further involvement in the SGP and how this correlated with their respective molecular weights.Subsequently,we proposed a practical method by which the SGP system was confined in nano-sized reactors.This method enabled the synthesis of a variety of polymers,having precisely controlled molecular weights with narrow polydispersity.We anticipate that this venture would exemplify a starting point for a more sophisticated molecular and structural design of functional polymers in widespread applications. | Yusen Wu Mingming Ding Jie Wang Bing Zhao Ziqi Wu Peng Zhao Donglai Tian Yun Ding Aiguo Hu | 2020 | CCS Chemistry2020，2，2： | 0 |
| 2 | A novel channel-wall engineering strategy for two-dimensional cationic covalent organic frameworks:Microwave-assisted anion exchange and enhanced carbon dioxide capture显示文摘A novel channel-wall engineering strategy of the porous materials cationic covalent organic frameworks(COFs)is established based on rapid microwave-assisted anion exchange reaction and utilized to prepare a set of new COFs.Due to the interaction between the carbon dioxide(C02)and the acetate anion,the resulting SJTU-COF-AcO shows greatly enhanced carbon dioxide capacity up to 1.7 times of the pristine COF.The effect of the counteranions to CO2 capacity in the cationic COFs is investigated for the first time,which demonstrates that our channel-wall engineering strategy is a promising way to tailor the property of COFs for high CO2 capacity. | Yusen Ding Yan Wang Yanjie Su Zhi Yang Jiaqiang Liu Xiaolin Hua Hao Wei | 2020 | Chinese Chemical Letters2020，31，1： | 0 |
