Monoclinic Copper(I) Selenide Nanocrystals and Copper(I) Selenide/Palladium Heterostructures: Synthesis, Characterization, and Surface‐Enhanced Raman Scattering Performance

Abstract

The ruthenium‐catalyzed dehydrogenative silylation of benzamides with 1,1,1,3,5,5,5‐heptamethyltrisiloxane took place at ortho‐positions of the benzene ring. Several benzamides containing both electron‐donating and electron‐withdrawing groups could be used in this silylation. Density functional theory (DFT) calculations and kinetic isotope effect experiments suggest that the catalytic cycle should involve the CSi bond formation as rate‐determining step.

Copper Iron Chalcogenide Semiconductor Nanocrystals in Energy and Optoelectronics Applications—State of the Art, Challenges, and Future Potential

“…[158] Inorganic and organic semiconductors can exhibit considerable SERS signal enhancements, however, the enhancement is typically ascribed to a chemical mechanism that is based on charge transfer. [159] Materials such as CuS and CuSe have been used for SERS, but only in conjunction with noble metals [160] and the signal enhancement of these materials alone is low. Therefore, the demonstration of pronounced SPR features in CuFeS 2 [51][52][53][54][55] promises new avenues in the exploration of, e.g., SERS substrates.…”

Common Aspects Influencing the Translocation of SERS to Biomedicine

“…Nanoscaled transition-metal chalcogenides (TMCs) show interesting properties arising from the synergetic effects between the component materials found in the heterostructures formed by a combination of metal NPs with semiconductors. In particular, Cu 2 Se/Pd heterostructures show greater SERS performance than pure Pd or Cu 2 Se revealing phase- and composition-dependent characteristics [27].…”
