Chinese Journal of Chemistry 2013年第5期31卷 617-623页

Macrocyclic CTV-Br3 reacted with the linear benzene-1,4-diboronic acid and 1,4-diethynylbenzene via Suzuki and Sonogashira-Hagihara coupling reactions producing the rigid porous materials CTV-CMP-1 and CTV-CMP-2. The porous materials have good thermal and chemical stability. The Brunauer-Emmet-Teller specific surface areas of CTV-CMP-1 and CTV-CMP-2 are 314 and 218 cm2·g^-1, respectively. Physical properties of the porous materi- als were investigated, CTV-CMP-1 showed moderate hydrogen adsorption about 0.81 wt% at 1.13 bar while CTV-CMP-2 showed lower hydrogen adsorption about 0.51 wt%. These materials are analogs to activated carbons which could be potentially used in gas separation and organic compound adsorption.

Mass Spectrometry Study of Non-Covalent Complexes of Bioflavonoids with cyclotriveratrylene Synthesized in Subcritical Water

引用

American Journal of Analytical Chemistry 2013年第9期4卷 464-468页

作者： Anna V. Lekar Sergey N. Borisenko Elena V. Vetrova Roman N. Borisenko Nickolay I. Borisenko Ecological Analytical Center of Southern Federal University Rostov-on-Don Russia Institute of Physical and Organic Chemistry Southern Federal University Rostov-on-Don Russia

Mass spectrometry was used for studying of non-covalent complexes of bioflavonoids with cyclotriveratrylene (CVT). The complexes of cyclotriveratrylene (CVT) with the bioflavonoids (quercetin or dihydroquercetin) have been synthesized in subcritical water. The complexe formation was carried out at different temperatures of subcritical water (from 120℃ to 230℃). The structure of the inclusion compounds was confirmed by the data of ESI MS spectroscopy. The mass spectrometry results showed the presence of mixed adducts of CTV monomer, dimer, trimer and tetramer with quercetin and dihydroquercetin. Composition of the CTV complexes with the bioflavonoids, which were obtained in subcritical water medium and by traditional method, was compared.

Homomeric Inclusion and Hydrogen-Bonding Cooperatively Directed Crystalline Assembly of a Cyclotriguaiacylene Derivative with Different Aromatic Acids

引用

Chinese Journal of Chemistry 2015年第7期33卷 765-770页

作者： Jingru Song Yanyan Shi Zhitang Huang Qiyu Zheng Beijing National Laboratory for Molecular Science CAS Key Laboratory of Molecular Recognition and Function Institute of Chemistry Chinese Academy of Sciences Beijing 100190 China

Five organic complexes are prepared by cocrystallization of tri-[（N-methyl-2-imidazoly）methoxy]cyclotriguiacylene （TMIM-CTG） with corresponding acids. While hydrogen bonds are the basic interactions in the five complexes, the homo-included motifs with C--H…π interactions also control the molecular arrangement except for complex 5. In complex 1, the two dimensional networks contain 1D zigzag chains formed by hydrogen bonding and 1D chains of homo-included CTG motifs. Complex 2 has 2D 4.82 hydrogen bonding networks, and the chains of homomeric inclusion extend the 2D structure to a 3D framework. Complex 3 contains four-membered rings through hydrogen bonds, and the chains of homo-inclusion link the rings to a novel 2D network. In complex 4, hydrogen bonds construct a novel double-layer 2D network, which is extended to a 3D framework by ＂hand-shake＂ dimeric homomeric inclusion interactions. Interestingly, there is no homomeric inclusion phenomenon in complex 5 and hydrogen bonds solely connect two components to a chiral （6,3） 2D network.

Synthesis and Properties of Porous Organic Polymers from a Rigid Macrocyclic Building Block

引用

Chinese Journal of Chemistry 2013年第5期31卷 577-581页

作者： Jingru Song Zhitang Huang Qiyu Zheng Beijing National Laboratory for Molecular Science CAS Key Laboratory of Molecular Recognition and Function Institute of Chemistry Chinese Academy of Sciences Beijing 100190 China

Two rigid macrocyclic CTV-based porous organic polymers, Click-POP-1 and Click-POP-2, have been synthe- sized by Click reaction of a cyclotriveratrylene analogue with alkyne groups and aromatic azides in one pot. FTIR, solid 13C NMR and elemental analysis confirmed the formation of the polymers. Both of them possess high thermo-stability which is up to 410 and 900 ℃, respectively, and moderate hydrogen storage properties with 0.46 wt% at 77 K. Their nitrogen uptake showed type-I isotherm with BET surface areas up to 342 and 317 m2·g ^-1.

关键词： cyclotriveratrylene porous organic polymer hydrogen uptake click reaction amorphous
