AI Technical Summary
Existing linearly polarized light-emitting materials, such as organic small molecules, organic polymers, inorganic nanomaterials, and polymeric liquid crystals, suffer from problems such as limited luminous efficiency, poor stability, difficulty in achieving wide-spectrum modulation, and poor processability, making it difficult to meet the needs of high-precision display and communication technologies.
The one-dimensional right-handed helical chiral organometallic halide [(PN)2Cu2(dca)X]n was prepared by self-assembly of the asymmetric organophosphorus ligand diphenyl-2-pyridinium phosphine with sodium dicyandiamide and cuprous halide in a hot saturated solvent, thus forming a structure with excellent linear polarization luminescence properties.
It achieves a photoluminescence quantum yield of up to 48.22% and a linear polarization ratio of up to 1.77, exhibiting good thermal stability and weather resistance, making it suitable for optoelectronic applications such as high-end anti-counterfeiting, quantum communication, and photonic devices.
