Transition metal complexes of copper subgroup metals are actively studied objects for temperature sensors. Their luminescence arising from the 3ILCT, 3MLCT or 3CC excited states is characterized by emission in all ranges of visible spectra and high quantum yields. Due to the ability of the complexes to emit in a dual band mode, these complexes are attractive for the temperature sensing in the ratiometric mode. Dual emission of complexes is usually susceptible of the irregular changes in intensity of two emission bands during the temperature changes. This is an important and necessary property for the utilization of phosphors as ratiometric thermometers. The structures and emission properties of gold(i) and copper(i) complexes are considered with the aim to demonstrate the possibility to apply such complexes as ratiometric molecular luminescent thermometers for the remote control of the object’s temperature.

Signal amplification by reversible exchange (SABRE) is a rapidly developing nuclear magnetic resonance (NMR) hyperpolarization technique utilizing parahydrogen for dramatic increase of NMR sensitivity to benefit its biomedical and analytic applications.

This mini-review covers the most important methodological advances of SABRE with the focus on recent developments. We discuss the mechanistic aspects of SABRE effects, hyperpolarization of protons and heteronuclei including the novel SABRE-Relay approach, the ongoing work to make SABRE biocompatible, the analytical applications, the advances in instrumentation and, finally, more exotic developments such as the low-field detection of SABRE and the SABRE-initiated radiofrequency amplification by stimulated emission of radiation (RASER) effects.

Mechanochemical tools in the synthesis of organometallic compounds

Volume 33, issue 3, pages 287–301

In response to rising environmental concerns, chemistry is experiencing a considerable change in both concepts and practices to adopt more efficient and sustainable technologies. One of the alternative technologies that offer many advantages over the conventional solution-based techniques is mechanochemistry which utilizes mechanical energy to induce chemical reactions. Despite the fact that mechanochemistry has reached high significance in the creation of advanced materials, such as alloys, ceramics, electrode materials, and nanocomposites, in the field of small molecule synthesis its potential remains largely untapped.

This review highlights the opportunities and prospects of different mechanochemical tools in the synthesis of organometallic compounds, including transition metal complexes with N-heterocyclic carbene, arene, and cyclopentadienyl ligands, monometallacyclic and pincer derivatives, as well as main group metal compounds (e.g., allyl complexes and the Grignard reagents). Many important organometallic transformations such as C–H bond metalation, transmetalation, and oxidative addition can be successfully implemented under mechanochemical conditions in a highly productive and energy-saving manner. Furthermore, the postmodification of metal-containing species upon grinding or milling is shown to be a powerful route to both new discrete metal complexes and different supramolecular architectures (metal-containing organic cages, macrocylces, networks).
