Covalent organic frameworks (COFs) are a class of promising photocatalysts for conversing light energy into chem. energy. Based on the tunable building blocks, COFs can be well-designed as photocatalyst for mediating reversible addition-fragmentation chain-transfer (RAFT) polymerization Herein, 1,3,6,8-tetrakis(4-formylphenyl)pyrene (TFPPy) and 2,2”-bipyridine-5,5”-diamine (Bpy) are chosen to construct imine-based TFPPy-Bpy-COFs for catalyzing RAFT polymerization of methacrylates under white light irradiation The well-defined polymers with precise mol. weight and narrow mol. weight distribution are obtained. The switch on/off light experiments suggest excellent temporal control toward RAFT polymerization system and the chain-extension reaction indicates high chain-end fidelity of macro-initiators. Mechanism study clarifies that the electron transfer between excited state of TFPPy-Bpy-COFs and RAFT agent can form living radicals to mediate polymerization This methodol. provides a novel platform for reversible-deactivation radical polymerization using COFs as heterogeneous catalysts.

Lu, Zhen;Yang, Hongjie;Fu, Xiaoling;Zhao, Rukai;Zhao, Yulai;Cai, Jingyu;Xiao, Longqiang;Hou, Linxi research published 《 Fully-π conjugated covalent organic frameworks as catalyst for photo-induced atom transfer radical polymerization with ppm-level copper concentration under LED irradiation》, the research content is summarized as follows. Photo-induced atom transfer radical polymerization (ATRP) becomes a significant method for preparing well-defined polymers with pre-designable mol. weight and narrow mol. weight dispersity (M_w/M_n). Herein, a fully-π covalent organic framework (COF) was constructed and served as heterogeneous photocatalyst for photo-induced ATRP under LED irradiation TCPB-DMTA-COF, which was constructed by Knoevenagel polycondensation of 1,3,5-tris(4-cynomethylphenyl)benzene (TCPB) and 2, 5-Dimethoxy-terephthalaldehyde (DMTA) and exhibited remarkable performance in mediating photo-induced ATRP of Me methacrylates with the assist of ppm-level concentration of Cu^II under LED irradiation, producing polymers with high chain-fidelity and low value of M_w/M_n (1.10-1.35). The switch “on/off” experiment exhibits excellent temporal and spatial control toward polymerization system. Compared with TCPB-DMTA-CMP, the high crystallinity and stability of TCPB-DMTA-COF endows high monomer conversion and good recyclability performance for photo-induced ATRP. These results suggest COF can be served as a promising artificial photocatalyst for photo-induced ATRP.

Liu, Zhibin;Chen, Fuchen;Sun, Jinyuan;Ni, Li research published 《 Dynamic changes of volatile and phenolic components during the whole manufacturing process of Wuyi Rock tea (Rougui)》, the research content is summarized as follows. Wuyi Rock tea (WRT), a top-ranking oolong tea, possesses characteristic woody, floral, nutty flavor. WRT flavor is mainly formed during the manufacturing process. However, details regarding its formation process are not fully understood yet. In this study, the dynamics of volatile and phenolic components over the whole manufacturing process of WRT were investigated. During withering, despite minor changes in volatile and phenolic components, the central vacuole shrunk remarkably, which reduced the cell mech. performance and facilitated the subsequent enzymic fermentation During fermentation, approx. 78% of flavan-3-ols in fresh tea leaves were oxidized and converted to a diverse mixture of highly heterogeneous oxidation products, such as theaflavins, whereas flavonols, phenolic acids, and xanthine alkaloids remained stable throughout the manufacturing process. Aldehydes, ketones, and heterocyclic compounds, imparting woody, floral, and nutty scent, were mainly formed during the roasting steps. This detailed information can expand our understanding on the formation of WRT flavor.

This work investigated the impact of co-fermentations of Oenococcus oeni and Lachancea thermotolerans on chem. constituents of spent coffee grounds (SCG) hydrolyzates with added yeast extract O. oeni Lalvin 31 and L. thermotolerans grew well in co-cultures, but the yeast died early in two co-cultures with O. oeni Enoferm Beta and O. oeni PN4. Compared with the monoculture of yeast only, co-inoculation with O. oeni did not significantly affect sugar consumption but reduced ethanol production In addition, co-fermentation significantly altered organic acids profiles. Furthermore, the fermented SCG hydrolyzates from co-culture of L. thermotolerans and O. oeni Lalvin 31 retained more alkaloids (e.g. theophylline and trigonelline) and had higher amounts of Et acetate, Me acetate and acetoin as compared with those of control. Hence, simultaneous malolactic fermentation by selected O. oeni and alc. fermentation by L. thermotolerans may provide a new strategy to valorize SCG for developing novel alc. beverages.
