Abstract

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.

铜亚族 d10 金属复合物的双发射是比率发光测温法的必要和充分条件吗？

铜亚族金属的过渡金属络合物是温度传感器的热门研究对象。它们由 3ILCT、3MLCT 或 3CC 激发态产生的发光具有在所有可见光谱范围内发射和量子产率高的特点。由于这些络合物能够以双波段模式发射，因此对于以比率模式进行温度传感非常有吸引力。复合物的双发射通常会在温度变化时出现两个发射带强度的不规则变化。这是荧光粉用作比率温度计的一个重要和必要的特性。本文研究了金（i）和铜（i）络合物的结构和发射特性，旨在证明将此类络合物用作远程控制物体温度的比率分子发光温度计的可能性。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
