Recently, the photoelectric functional materials team of the School of Chemistry and Chemical Engineering of our university made a breakthrough in the field of organic-inorganic hybrid manganese halide Circularly polarized luminescence (CPL). The results are described as "Circularly Polarized Luminescence Induced by Hydrogen-Bonding Networks in a One-Dimensional Hybrid Manganese(II)" Chloride "was published in Angewandte Chemie International Edition, a leading international journal in the field of chemistry. The first author of this paper is Li Jing, a 2020 PhD candidate in the School of Chemistry and Chemical Engineering of Guangxi University, and the first corresponding author is Professor Pang Qi, School of Chemistry and Chemical Engineering of Guangxi University. Guangxi University is the first communication unit of this paper.
At present, CPL materials are widely used in many optoelectronic fields such as 3D optical display, photonics encryption transmission and information storage, X-ray imaging and optical sensors. Organic-inorganic hybrid metal halides with excellent luminescence properties and unique chiral structures are expected to become a new class of CPL functional materials. How to achieve high photoluminescence quantum yield, high thermal quenching resistance and large luminescent asymmetry factor in metal halide materials is a challenge in this popular research field.
In the face of this great challenge, the team designed and prepared hybrid manganese halide single crystals with excellent CPL properties through chiral molecular induction, using hydrogen bond networks, and revealed the source of chiral optical activity and the reason why the luminescence quantum yield is close to 100%. This work provides important guidance for the structural design, crystal growth and photoelectric application of multifunctional chiral hybrid metal halide materials.
