Novel Non‐Coplanar and Tertbutyl‐Substituted Polyimides: Solubility, Optical, Thermal and Dielectric Properties
Chinese Journal of Chemistry - Tập 33 Số 2 - Trang 277-284 - 2015
Chanjuan Liu, Xianglin Pei, Xiaohua Huang, Chun Wei, Xiaoyi Sun
AbstractA novel aromatic diamine monomer bearing tertbutyl and 4‐tertbutylphenyl groups, 3,3′‐ditertbutyl‐4,4′‐diaminodiphenyl‐4′′‐tertbutylphenylmethane (TADBP), was prepared and characterized. A series of non‐coplanar polyimides (PIs) were synthesized via a conventional one‐step polycondensation from TADBP and various aromatic dianhydrides including pyromellitic ...... hiện toàn bộ
Si/C Composites as Negative Electrode for High Energy Lithium Ion Batteries
Chinese Journal of Chemistry - Tập 35 Số 1 - Trang 21-29 - 2017
Yi Zhang, Yusong Zhu, Lijun Fu, Jixing Meng, Nengfei Yu, Jing Wang, Yuping Wu
AbstractSilicon is very promising negative electrode materials for improving the energy density of lithium‐ion batteries (LIBs) because of its high specific capacity, moderate potential, environmental friendliness, and low cost. However, the volume variation of Si negative electrodes is huge during lithi...... hiện toàn bộ
Tailoring Excited State Properties and Energy Levels Arrangement via Subtle Structural Design on D‐π‐A Materials
Chinese Journal of Chemistry - Tập 35 Số 10 - Trang 1559-1568 - 2017
Xiaoming Liang, Zhiheng Wang, Liangxuan Wang, Muddasir Hanif, Dehua Hu, Shi‐Jian Su, Zengqi Xie, Yu Gao, Bing Yang, Yuguang Ma
The donor‐π‐conjugated‐acceptor (D‐π‐A) structure is an important design for the luminescent materials because of its diversity in the selections of donor, π‐bridge and acceptor groups. Herein, we demonstrate two examples of D‐π‐A structures capable to finely modulate the excited state properties and arrangement of energy levels, TPA‐AN‐BP... hiện toàn bộ
Design of Polymers for Intracellular Protein and Peptide Delivery
Chinese Journal of Chemistry - Tập 39 Số 6 - Trang 1443-1449 - 2021
Yiyun Cheng
AbstractCytosolic protein delivery techniques are of great importance for cell biology, biotechnology and protein drug development. The design of carriers with robust efficiency in cytosolic protein delivery is challenging. This account provides a progress report of polymeric carriers for this purpose in our group. During the past years, we have developed several t...... hiện toàn bộ
One‐Pot Aqueous Synthesis of Highly Biocompatible Near Infrared CuInS2 Quantum Dots for Target Cell Imaging
Chinese Journal of Chemistry - Tập 34 Số 6 - Trang 576-582 - 2016
Anila Arshad, Hongli Chen, Xilin Bai, Suying Xu, Leyu Wang
AbstractIn this study, we report a novel and facile autoclave strategy for synthesis of near‐infrared (NIR) CuInS2 QDs by employing glutathione (GSH) as capping ligand and stabilizer in aqueous media under 100°C. Various experimental parameters including the ratio of precursors, reaction time, reaction temperature, pH effect and stability have ...... hiện toàn bộ
Gemini Surfactants Templated Mesoporous Silica Microparticles: from Solid to Hollow Mesoporous Spheres
Chinese Journal of Chemistry - Tập 35 Số 11 - Trang 1706-1710 - 2017
Min Li, Chun Zhang, Xiangliang Yang
We synthesized a series of mesoporous silica microparticles (MSs) using cationic gemini surfactants C14–2‐n (n = 2, 6, 10, 14) as templates. The porous structures and pore size of these MSs can be tuned by varying the length of alkyl chain in gemini surfactant templates. These MSs showed effective doxorubicin (DOX) ...... hiện toàn bộ
(Solid+Liquid) Equilibria in the Quaternary System Na2B4O7‐MgB4O7‐K2B4O7‐H2O at 288 K
Chinese Journal of Chemistry - Tập 28 Số 5 - Trang 755-758 - 2010
Song Shihua, Jiang Peng
Abstract(Solid+Liquid) phase equilibria in the quaternary system Na2B4O7‐MgB4O7‐K2B4O7‐H2O at 288 K were studied experimentally using the method of isothermal solution saturation...... hiện toàn bộ
High Performance Supercapacitors from Hierarchical Porous Carbon Aerogels Based on Sliced Bread
Chinese Journal of Chemistry - Tập 35 Số 5 - Trang 699-706 - 2017
Pin Hao, Guanwei Cui, Xifeng Shi, Junfeng Xie, Xinyuan Xia, Yuanhua Sang, C.P. Wong, Hong Liu, Bo Tang
Supercapacitor electrodes with porous structure based on renewable, eco‐friendly and cost‐effective materials have caused extensive concern in energy storage fields. Sliced bread, the common food ingredient, mainly containing glucose polymers, can be a promising candidate to fabricate porous supercapacitor electrodes. Highly porous carbon aerogels by using sliced bread as the raw material ...... hiện toàn bộ
A new Sequiterpenoid from Eupatorium adenophorum Spreng
Chinese Journal of Chemistry - Tập 24 Số 10 - Trang 1375-1377 - 2006
Lan He, Jie Yang, Aocheng Cao, Yumei Liu, Yu An, Jian‐Gong Shi
AbstractA new sequiterpenoid compound 8aα‐hydroxy‐1‐isopropyl‐4,7‐dimethyl‐1,2,3,4,6,8a‐hexahydro‐naphthalene‐2,6‐dione (1), together with seven known compounds anti‐HH‐dimer‐coumarin (2), (−)‐5‐exo‐hydroxy‐borneol (3), O... hiện toàn bộ
Defensive Sesquiterpenoids from Leaves of Eupatorium adenophorum
Chinese Journal of Chemistry - Tập 30 Số 6 - Trang 1331-1334 - 2012
Wei Shi, Shi‐Hong Luo, Sheng‐Hong Li
AbstractThe invasive plant Eupatorium adenophorum Spreng has caused great economic loss in China, and is gravely threatening the native biodiversity and ecosystem. The plant has been phytochemically investigated for the defensive chemical substances in its leaves. Three active sesquiterpenoids were isolated and identified, which include a...... hiện toàn bộ
