| 1 | GCC Countries’Future Relationship With the Shanghai Cooperation Organisation:Motivation and Prospect显示文摘The Gulf Cooperation Council(GCC)is the most important economic,energy and political coalition in the Middle East.The Shanghai Cooperation Organisation(SCO)is the most influential Eurasian political and economic bloc.In the vicissitude international situation,the SCO is expanding westward;Qatar and Saudi Arabia have become the partners of dialogue;Bahrain,Kuwait and the UAE have applied for being partners for dialogue.Likewise,the GCC is looking eastward,exploring cooperation with Russia within the framework of‘OPEC+’,with China in‘China-GCC Summit and China-GCC Strategic Dialogue’,and with India within the framework of I2U2(Israel,India,United States and the United Arab Emirates).The‘SCO+GCC+’cooperation mechanism is inclusive,compatible with the US,European and the NATO’s military engagement with the GCC,which will open a new ground for bilateral cooperation and multilateral interaction between East Asia,South Asia,Central Asia,North Asia and West Asia,conducive to building‘an Asian community of shared future’in the long run. | Degang Sun Fanxi He | 2023 | Asian Journal of Middle Eastern and Islamic Studies2023，17，1： | 0 |
| 2 | Visible-Light-Responsive Crystalline Solids by Equipping Covalent Organic Frameworks with Donor-Acceptor Stenhouse Adducts显示文摘Controlling properties of crystalline solids by light remains a challenge because the lack of intrinsic structural flexibility limits the necessary molecular mobility for photoisomerization. In this work, we reported a series of visible-light-responsive covalent organic frameworks (COFs) by introducing donor-acceptor Stenhouse adducts (DASAs) with various electron-withdrawing moieties via a post-modified strategy. The DASAs-functionalized COFs exhibit distorted honeycomb layered topology with long-range periodicity. The DASAs grafted on the skeletons are pointing into the nanopores of COFs, which weakens intermolecular aggregation and ensures sufficient free volume to undergo reversible isomerization between linear and cyclic states. Furthermore, the crystalline and optical properties of COFs as well as the geometrical size and hydrophilicity inside the nanopores were reversibly controlled by alternating visible light irradiation and heat. Finally, methyl violet was used as the cargo molecules to be immobilized into the nanopores of COFs, which showed fast release under controlling of visible light. | Yongli Duan Fanxi Sun Ang Gao Zhen Wang Xiaoyu Xiong Lijun Mao Bo Han Chao He Xu Deng Yonghao Zheng Dongsheng Wang | 2023 | Chinese Journal of Chemistry2023，41，19： | 0 |
