It is challenging to precisely regulate the chirality transmission of metal–organic supramolecular polymers (MOSPs) due a poor understanding nucleation pathways during highly dynamic and complex self-assembly process. This work reports circularly polarized luminescence (CPL) switching pyridine Schiff-base cholesterol (2-PMPCC) ZnCl2-based MOSPs with inversion CPL through competition solvent-assisted thermal nucleation. In p-xylene, metal 2-PMPCC·ZnCl2 conducted assembled into metastable twisted nanoribbons Agg I right-handed at 490 nm, which further reverted thermodynamic II left-handed nm. contrast, nanosheet-like III 460 nm in ethanol. Based on nucleation, significant morphology were achieved by tuning temperature cosolvents p-xylene revealed transfer transformation regulated solvent-dependent MOSPs, providing an efficient approach control tunable performances for design chiroptical materials.

Constructing circularly polarized luminescence (CPL) materials that exhibit dynamic handedness inversion and emissive color modulation for multimodal information encryption presents both a significant challenge compelling opportunity. Here, we have developed pyridinethiazole acrylonitrile-cholesterol derivative (Z-PTC) exhibits wavelength-dependent photoisomerization photocyclization, enabling in supramolecular assemblies with decent CPL activity.

Abstract Ultrasound‐induced circularly polarized luminescence (CPL) was achieved using planar chiral, binuclear clothespin‐shaped trans‐ bis(salicylaldiminato)platinum(II) complexes. Solutions of the platinum(II) complexes anti ‐ 1a–c in cyclohexane immediately transformed into stable gels upon brief ultrasound irradiation. The exhibited intense phosphorescent emissions at room temperature, whereas none solution significant under UV light illumination. Interestingly, prepared from optically pure CPL activity temperature with an anisotropy factor | g lum = 1.5–2.6 × 10 −3 . emissive were readily converted to original non‐emissive heating and cooling could be gelled again by In addition, chromogenic control green red emission can simply introducing MeO groups different positions on aromatic rings.

Achieving circularly polarized luminescence (CPL) with room-temperature phosphorescence (RTP) is a significant but challenging issue. Here, simple method for preparing phosphorescent (CPP) materials adopted through the chiral coordination assembly. One enantiomeric pair of polymers (DCF-13 and LCF-13) synthesized by introducing linker. DCF-13 LCF-13 RTP lifetimes 132.45 137.36 ms can emit CPP glum values −5.0 × 10–3 +5.0 at 450 nm. This work provides perspective constructing materials.

Abstract Supramolecular chirality is the major branch of supramolecular chemistry, which not only plays important roles in biological processes but also synthetically designed aggregated systems. To understand complex processing systems, way to design chiral ensembles that mimic natural biomolecules such as Deoxyribonucleic acid (DNA), Ribonucleic (RNA), amino acids, etc. In addition, systems and self‐assemblies molecular motifs with breaking spatial inversion symmetry have been regarded key substances electronics spintronics well fundamental chemistry physics. Here, this review, our concern understanding modulation arrangements packing modes under impact any external stimuli, results tailoring handedness resulted superstructures. We, highlighted role stimuli solvent, chemical additives, photo exposure, altering for their future utility “active switches” optoelectronic spintronic devices applications.
