Description

technical field

[0001] The invention relates to a near-infrared organic electroluminescence material, a device and a preparation method of the device. Background technique

[0002] Photonics has always been fundamental to driving the development of communication technology, but within a decade, existing technologies and devices will not be able to meet the requirements of future applications. In order to solve the above problems, countries all over the world are competing to develop new photonic materials and high-performance photonic devices to meet the requirements of ultra-fast and large-capacity information processing in the future. It is agreed that future optical components should have the characteristics of high integration and low processing cost . Recent advances in organic materials and related optoelectronic devices have demonstrated the potential of organic materials for low processing costs and multifunctionality required for communication applications due to t...
