Abstract
The invention provides a silole derivative with a general formula (I). The definition of each group in the formula is shown in the specification. The silole derivative with the general formula (I) hasaggregation-induced emission performance, and is particularly suitable for light-emitting parts and devices, fluorescent probes, biological imaging, lubricating oil and lubricating grease. The invention provides a photoluminescent lubricating grease composition containing a luminescent material. The lubricating grease composition disclosed by the invention has photoluminescence property and one or more properties of oxidation resistance, wear resistance, extreme pressure property and rust resistance. The lubricating grease composition disclosed by the invention can be applied to related mechanical equipment in the electric appliance industry, the metallurgical industry, the food industry, the papermaking industry, the automobile industry and the airplane industry.
Description
technical field [0001] The invention relates to a photoluminescent material, in particular to a photoluminescent material with aggregation-induced luminescent properties and a photoluminescent grease composition containing the photoluminescent material with aggregation-induced luminescent properties. Background technique [0002] Traditional organic chromophoric materials usually have strong luminescence at low concentrations, but weak or even no luminescence at high concentrations or solid state, showing aggregation fluorescence quenching effect. This is due to the fact that in the aggregated state, the strong interaction between molecules leads to an enhanced non-radiative decay process of the excited state, and a significant decrease in the fluorescence quantum yield. In the actual application process, the aggregation fluorescence quenching effect largely limits the practical application of organic light-emitting materials. Recent studies have found that some compounds e...
