General description

In the presence of a Pd catalyst, this reagent cross-couples with aryl bromides to give styrene derivatives.

Application

  • Cyclic siloxanes conjugated with fluorescent aromatic compounds as fluoride sensors: This study explores the use of cyclic siloxanes conjugated with aromatic compounds for sensing applications, offering a pathway for academic chemists interested in sensor technology and fluorescence studies (N Prigyai et al., 2020).
  • Synthesis, film morphology and performance of novel crosslinked polysiloxane with end-capped epoxy groups on cotton substrates: This article examines the chemical modification of cotton substrates using polysiloxane derivatives, which can be crucial for developing advanced textile coatings (L Hao et al., 2014).
  • Stabilizing Li-rich layered oxide cathode interface by using silicon-based electrolyte additive: This research investigates the use of a silicon-based additive derived from 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane to enhance the stability of lithium-rich cathodes, important for chemists working with energy storage technologies (T Huang et al., 2024).

Liquid crystalline elastomers (LCE) undergo reversible shape changes in response to stimuli, which enables a wide range of smart applications, in soft robotics, adhesive systems or biomedical medical devices. In this study, we introduce a new dynamic covalent chemistry based on

We show that submicron-sized patterns can be imprinted into soft, recombinant-engineered protein hydrogels (here elastin-like proteins, ELP) by transferring wavy patterns from polydimethylsiloxane (PDMS) molds. The high-precision topographical tunability of the relatively stiff PDMS is translated to a bio-responsive, soft

Adjustable fluidic structures play an important role in microfluidic systems. Fracture of multilayered materials under applied tension has been previously demonstrated as a convenient, simple, and inexpensive approach to fabricate nanoscale adjustable structures; here, it is demonstrated how to extend

Nanoimprinting with rigid molds offers almost unlimited pattern resolution, but it suffers from high sensitivity to defects, and is limited to pattering flat surfaces. These limitations can be addressed by nanoimprinting with soft molds. However, soft molds have been used

Nanowires (NWs) with a high surface-to-volume ratio are advantageous for bio- or chemical sensor applications with high sensitivity, high selectivity, rapid response, and low power consumption. However, NWs are typically fabricated by combining several nanofabrication and even microfabrication processes, resulting
