A water-stable and pH-independent sensor for qualitative quantitative detection of nicotine in urine solution living cell was successfully developed. This material, named MB@UiO-66-NH2, can be synthesized by encapsulating methylene blue (MB) with a well-known metal-organic framework (MOF) UiO-66-NH2 through simple impregnation method. The fluorescence intensity the system significantly enhanced when certain amount added. In meanwhile, MB is reduced reductive to form leucomethylene (LB)....
A metal-free, photocatalyst-free, photochemical system was developed for the direct alkylation of thiophenols via electron donor–acceptor (EDA) complexes (KEDA = 145 M–1) between two reactants, N-hydroxyphthalimide esters as acceptors and thiophenol anions donors, in presence a tertiary amine. The EDA reaction have broad range visible-light absorption (400–650 nm) can trigger effectively under sunlight.
Successive energy-transfer-mediated dearomative [2π + 2σ] cycloaddition/1,6-HAT cascade reaction of quinolines with bicyclo[1.1.0]butanes provides a facile synthesis pyridine-fused 3D complicated molecules.
A visible light-driven dearomatization of an N -( o -haloarylformyl)indole in electron donor–acceptor (EDA) complex with a thiophenol. The radical reaction is terminated by concerted hydrogen atom transfer (HAT).
A new donor-two-acceptor modular fluorescence rotor DpCy7 involving a phenolate donor unit and two benzothiazolium acceptor moieties was designed synthesized. The underwent an internal charge transfer to form Cy7-like longer conjugated system fluorochrome at physiological pH. probe exhibited strong turn-on (8.5-fold) deep-red emission with larger Stokes shift in glycerol aqueous solutions restriction of rotation. Both the intensity lifetime displayed linear relationship viscosity changes...
There are some synthesis methods from widely available aldehydes to the corresponding ketones, however, they involved in multistep reactions with Grignard's reagents or transition metal catalysts. In this paper, we have developed photocatalyst-free and visible light-driven decarboxylative alkylation of pyridinaldehydes. The photochemical initiated via photoinduced single electron transfer triethylamine N-hydroxyphthalimide esters donor-acceptor complexes. This method can achieve translate 15...
Abstract China began to implement a draconian population policy in the early 1980s. This has experienced many adjustments, as well amendments, since then, and even overturn 2010s from birth control natalism. study examines Chinese women’s reproductive rights trajectory of China’s last four decades. It applies analytical framework made up United Nations Convention on Elimination All Forms Discrimination against Women, International Conference Population Development Program Action, Beijing...
Abstract A visible‐light triplet photocatalyst 5‐acetyl‐2‐mercapto‐benzoic acid methyl ester (AcBSH) was developed through introducing acetyl into benzenethiolate to improve the efficiency of intersystem crossing (ISC) and using o ‐methoxyformyl increase molar extinction coefficient. In photocatalytic system AcBSH, reductive dearomatization N ‐arylformylindoles is achieved afford desired indolines in moderate excellent yields, including both indoles without ( 1 ) with 2‐substituent 2 ). The...
450 Feminist Studies 47, no. 2. © 2021 by Studies, Inc. Cai Yiping What Do Gender Equality and Women’s Rights Have to with China’s Global Engagement? The year 2020 marked the twenty-fifth anniversary (Beijing+25) of Fourth World Conference on Women (4WCW) held in Beijing 1995. At that meeting, 189 members states United Nations unanimously adopted Declaration Platform for Action (BPfA), committing a comprehensive visionary agenda gender equality realization women’s human rights.1 Since then,...
A new"family"of coordination catalysts based on rare-earth for stereos-pecific polymerization of acetylene has been developed the preparation high cis(>90%)polyacetylene(PA)films at 30℃. Rare-earth PA was silvery flexible with metallic luster. The highly conducting complexes are obtained by do poing electron acceptors(I2,Br2,etc.). maximum conductivity(σ)of doped films room temperature is approxima-tely 1000 ohm-1·cm-1 iodine,corresponding to a concentration about 12.5mol% where σ increased...
