The molecular electronic devices based on self-assembled monolayer (SAM) on metal surfaces demonstrate novel electronic functions for device minimization yet are unable to realize in practical applications, due to their instability against oxidation of the sulfur-metal bond. This paper describes an alternative to the thiolate anchoring group to form stable SAMs on gold by selenides anchoring group. Because of the formation of...

Hepatic ischemia-reperfusion injury (HIRI) is a critical complication after liver surgery that negatively affects surgical outcomes of patients with the end-stage liver-related disease. Reactive oxygen species (ROS) are responsible for the development of ischemia-reperfusion injury and eventually lead to hepatic dysfunction. Selenium-doped carbon quantum dots (Se-CQDs) with an excellent redox-responsive pro...

In contrast to other main group elements, group VI elements are rarely observed to form long linear polymer main chains. We reported the synthesis and characterizations of polytelluoxane, a polymer with an inorganic main chain that constitutes tellurium and oxygen, which may bridge the gap between inorganic oxides and macromolecules. Polytelluoxane has a flexible Te–O backbone and can be facilely synthesized and further p...

Polymerization inside living cells provides chemists with a multitude of possibilities to modulate cell activities. Considering the advantages of hyperbranched polymers, such as a large surface area for target sites and multilevel branched structures for resistance to the efflux effect, we reported a hyperbranched polymerization in living cells based on the oxidative polymerization of organotellurides and intracellular redox environment. The intracellular hyperbranched polymerizati...

Significant progresses have been made in tellurium-containing polymers over the past decades. Just like other heteroatom-containing polymers, tellurium-containing polymers exhibit several unique properties and promising applications. However, unlike elements such as boron, silicon, sulfur and so on, tellurium in polymers remains a fresh perspective for many researchers. In this review, we shall illustrate the diversification of tellurium-...

Shuojiong Pan, Jun Guan, Banruo Xianyu, Yizheng Tan, Tianyu Li, and Huaping Xu Adv. Mater.; 2023, 23, 2211370. As a specialized immune effector cell, natural killer (NK) cells play a very important role in immunotherapy, but tumor immunosuppression caused by abnormal expression of cancer cells seriously weakens its therapeutic effect and leads to exhaustion. Here, we developed a self-assembled selenium containing nanoparticles (NPs) composed of Cetuximab, C5SeSeC5 and inhibitor LY345899 to reverse NK cell exhaustion. The obtained NPs can target EGFR on the surface of cancer cells and locat...

Jinyan Si, Peng Zhao, Jun Guan, Shaobo Ji and Huaping xu Langmuir; 2022, 38, 13272 A diselenide bond, as a dynamic covalent bond, is a versatile tool to construct smart interfaces, which can respond to visible light. In this work, we used microcontact printing (μCP) to construct diselenide patterns on quartz substrates. Fluorescent patterns were obtained on the modified surfaces via the visible-light-induced diselenide metathesis reaction, which allowed the patterning process to be fast, dynamically erasable, and compatible with different fluorescent molecules including rhodamine B and b...

Cheng Liu, Shaobo Ji and Huaping Xu Matter; 2022, 3, 2397. A rapid and reprogrammable alignment strategy for the reversible actuation of liquid crystal elastomers has been achieved through the phase-transition-induced shape memory effect. This breakthrough, recently reported in Advanced Materials by Xie and colleagues, illustrated the important role of shape-memory-induced stress regulation in developing and improving functional polymer materials.

Xiaoying Kang, Yuan Yuan, Huaping Xu and Yulan Chen Chem. Res. Chinese Universities, 2022, 38, 516. Thermal- and light-driven diselenide metathesis reactions with different types of diselenides are investigated systematically. Their exchange reaction rates and equilibrium conversions are compared in the aspects of the different diselenide structures, activation conditions and solvents. As a result, the metathesis reactions between diselenide small molecules are demonstrated with high dynamic and sensitive features, which can be broadly tuned by varying the electron affinity and aromaticity o...
