Zhuo, Ming-Peng;Su, Yang;Qu, Yang-Kun;Chen, Song;He, Guang-Peng;Yuan, Yi;Liu, Hao;Tao, Yi-Chen;Wang, Xue-Dong;Liao, Liang-Sheng research published 《 Hierarchical Self-Assembly of Organic Core/Multi-Shell Microwires for Trichromatic White-Light Sources》, the research content is summarized as follows. White-light-emissive organic micro/nanostructures hold exotic potential applications in full-color displays, on-chip wavelength-division multiplexing, and backlights of portable display devices, but are rarely realized in organic core/shell heterostructures. Herein, through regulating the noncovalent interactions between organic semiconductor mols., a hierarchical self-assembly approach of horizontal epitaxial-growth is demonstrated for the fine synthesis of organic core/mono-shell microwires with multicolor emission (red-green, red-blue, and green-blue) and especially organic core/double-shell microwires with radial red-green-blue (RGB) emission, whose components are dibenzo[g,p]chrysene (DgpC)-based charge-transfer (CT) complexes. In fact, the desired lattice mismatching (∼2%) and the excellent structure compatibility of these CT complexes facilitate the epitaxial-growth process for the facile synthesis of organic core/shell microwires. With the RGB-emissive substructures, these core/double-shell organic microwires are microscale white-light sources (CIE [0.34, 0.36]). Besides, the white-emissive core/double-shell microwires demonstrate the fascinating full-spectrum light transportation from 400 to 700 nm. This work indeed opens up a novel avenue for the accurate construction of organic core/shell heterostructures, which provides an attractive platform for the organic integrated optoelectronics.

Zhuo, Ming-Peng;He, Guang-Peng;Wang, Xue-Dong;Liao, Liang-Sheng research published 《 Organic superstructure microwires with hierarchical spatial organisation》, the research content is summarized as follows. Rationally designing and precisely constructing the dimensions, configurations and compositions of organic nanomaterials are key issues in material chem. Nevertheless, the precise synthesis of organic heterostructure nanomaterials remains challenging owing to the difficulty of manipulating the homogeneous/heterogeneous-nucleation process and the complex epitaxial relationships of combinations of dissimilar materials. Herein, we propose a hierarchical epitaxial-growth approach with the combination of longitudinal and horizontal epitaxial-growth modes for the design and synthesis of a variety of organic superstructure microwires with accurate spatial organization by regulating the heterogeneous-nucleation crystallization process. The lattice-matched longitudinal and horizontal epitaxial-growth modes are sep. employed to construct the primary organic core/shell and segmented heterostructure microwires. Significantly, these primary organic core/shell and segmented microwires are further applied to construct the core/shell-segmented and segmented-core/shell type′s organic superstructure microwires through the implementation of multiple spatial epitaxial-growth modes. This strategy can be generalised to all organic microwires with tailored multiple substructures, which affords an avenue to manipulate their phys./chem. features for various applications.

Zuo, Linsen;Wu, Chenjiang;Tong, Lifen;Liu, Xiaobo research published 《 Improving interfacial properties of polyarylene ether nitrile/aramid fiber composite through hydrogen bonding interaction combined with molecular weight adjustment》, the research content is summarized as follows. Aramid fiber (AF)-reinforced composite is a material with high performance and great potential. In this work, polyarylene ether nitrile terminated with phthalonitrile (PEN-t-Ph) is used to modify the AF surface, and hydrogen bonds are formed between the AF and PEN-t-Ph resin, as shown by Fourier IR anal. Then modified AF (m-AF)/PEN-t-Ph composite laminate is prepared by hot-pressing, and the influence of mol. weight of PEN-t-Ph on performance of the m-AF/PEN-t-Ph composite laminate is studied. The PEN-t-Ph were named PEN-1, PEN-2, PEN-3 and PEN-4 according to mol. weight from large to small. And the mech. properties and interface compatibility of m-AF/PEN-n composite laminates initially increase and then decrease as the mol. weight of the PEN-t-Ph resin decreases. The m-AF/PEN-3 composite laminate has the best mech. performance with an interlaminar shear strength of 94 MPa that is 95% higher than the lowest values among the four samples. In addition, m-AF/PEN-3 has the best impact strength of 133.70 kJ/m², and in the dynamic mech. anal. test, m-AF/PEN-3 has a leading storage modulus with 62 GPa at 120°C which is 50 GPa higher than for the lowest sample. In general, the mol. weight of the PEN-t-Ph resin has a greater impact on performance of the m-AF/PEN-t-Ph composite laminates, and appropriate adjustment of mol. weight of the PEN-t-Ph resin will help improve the comprehensive performance of the m-AF/PEN-t-Ph composite laminate and provides a new way for preparing AF-reinforced materials.

Yuan, Pengtao;Jiang, Xi;Wang, Siyu;Shao, Xusheng;Yang, Qing;Qian, Xuhong research published 《 X-ray Structure and Molecular Docking Guided Discovery of Novel Chitinase Inhibitors with a Scaffold of Dipyridopyrimidine-3-carboxamide》, the research content is summarized as follows. Chitinases are the glycosyl hydrolase for catalyzing the degradation of chitin and play an indispensable role in bacterial pathogenesis, fungal cell wall remodeling, and insect molting. Thus, chitinases are attractive targets for therapeutic drugs and pesticides. Here, we present a strategy of developing a novel chemotype of chitinase inhibitors by the construction of planar heterocycles that can stack with conserved aromatic residues. The rational design, guided by crystallog. anal. and docking results, leads to a series of dipyridopyrimidine-3-carboxamide derivatives as chitinase inhibitors. Among them, compound 6t showed the most potent activity against bacterial chitinase SmChiB and insect chitinase OfChi-h, with a K_i value of 0.14 and 0.0056μM, resp. The strong stacking interaction of compound 6p with Trp99 and Trp220 found in the SmChiB-6p co-crystal structure verifies the feasibility of our design. Our results provide novel insights into developing potent chitinase inhibitors for pathogen and pest control.
