“…8b We also explored the application of 3au with Suzuki coupling to generate 6a, which exhibits promising chiral photoluminescent properties (figure 2d). 12 Based on our observations and the experimental results, we are intrigued by the reaction mechanism. The catalyst resting state was initially identified by a control experiment with in situ NMR.…”

Nickel demonstrates excellent performance in C-C or C-X cross-coupling reactions involving a SET process. However, the Ni(I)/Ni(III) two-electron pathway, which does not require light irradiation, is still rare, particularly in the asym-metric version. Here, we disclose a Ni(II)-catalyzed asymmetric C-P cross-coupling reaction via the Ni(I)/Ni(III) two-electron redox pathway. Combined experimental and computational research reveals that Ni(II) can be readily reduced to Ni(0) by secondary phosphine oxides, resulting in the formation of a Ni(I) active catalyst through comproportiona-tion. The discovery of the Ni(I)/Ni(III) two-electron mechanism may serve as a new paradigm of Ni catalysis, offering exciting opportunities in asymmetric reactions complementary to the traditional SET process.

“…or chemical bonds (covalent bonds, hydrogen bonds, and ionic bonds) upon endogenous or exogenous mechanical stimulation, while these changes could serve as the source for controllable drug release. 18,39 And according to the stimulation sources, mechanical forceresponsive DDSs are divided into endogenous DDSs that respond to mechanical forces from the body's internal compression, tension, or shear forces, 32,33,[40][41][42] and exogenous DDSs that respond to external magnetism or ultrasound. Thanks to widespread and easily accessible mechanical stimuli, a mechanical force-responsive DDS is expected to achieve high precision and deep penetration level drug delivery at the desired location and time.…”

The term “smart materials” can be used to refer a wide variety of different kinds of substances. One capacity that is shared by all of them is the capability to radically alter one or more aspects while operating inside carefully controlled conditions. The age of intelligent materials is arrived, and we are living in it right now. An older definition of smart material described it as a substance that responds swiftly to the environment in which it is located. It has been argued that the word “smart material” now refers to any substance that is capable of detecting, transmitting, or processing a stimulus in order to produce a beneficial effect. This idea has been put forward as a possible expansion of the original meaning of the term. The purpose of this research is to define and categorize different types of intelligent materials. Uses of smart materials are being contemplated in a wide variety of domains, spanning from the realm of technology to that of the modern environment.
