Side-Chain Engineering of Organic Crystals for Lasing Media with Tunable Flexibility

Baolei Tang et al.

Summary: Abundant high-performance organic crystals have been reported, but their brittleness restricts their applications. Some organic crystals have been designed to be deformable, but their development relies on molecular framework design. In this study, a side-chain engineering strategy is proposed to easily modulate the mechanical compliance of organic crystals. Changing the side chains subtly alters the mechanical behaviors while maintaining the unique optical functions. The potential applications of the flexible crystals as soft optical transducing media are evaluated through optical waveguides and amplified spontaneous emissions.

Visible Helicity Induction and Memory in Polyallene toward Circularly Polarized Luminescence, Helicity Discrimination, and Enantiomer Separation

Lei Xu et al.

Summary: Inspired by natural helices like DNA, the researchers successfully induced one-handed helical structures in achiral polymers using chiral amines and alcohols, and the induced helices were able to maintain their structure even after the chiral inducer was removed. These induced helices formed stable gels and showed helicity discrimination ability. They also demonstrated efficient enantioselective crystallization and separation of enantiomers. This research has significant implications for developing novel chiral materials.

Coordination Sphere Flexibility Leads to Elastic Deformation in a One-Dimensional Coordination Polymer Crystal

Sajesh P. Thomas et al.

Summary: This article reports a mechanically flexible one-dimensional coordination polymer that exhibits elastic bending. By utilizing various techniques including XRD, high-pressure crystallography, synchrotron micro-XRD mapping, and high-resolution synchrotron X-ray charge density analysis, the inter and intra-chain bonding as well as structural flexibility were quantitatively investigated. The results reveal that the helical coordination polymer behaves like a spring when subjected to external stimuli. The exceptional coordination sphere flexibility, attributed to the presence of Jahn-Teller distorted coordination bonds, contributes to the polymer's flexibility.

Crystals of Aliphatic Derivatives of [Cu(acac)2] have Distinct Atomic-Scale Mechanisms of Bending

Amy J. J. Thompson et al.

Summary: Molecular crystals of aliphatic derivatives with noticeable elasticity were synthesized and their mechanisms of elasticity were studied. Crystallographic mapping at an atomic-scale revealed that the elasticity of these compounds is facilitated by expansion of their π-stacking interactions. The findings distinguish their mechanisms from the previously reported mechanism of bis(acetylacetonato)copper(II).

Atomic-resolved hierarchical structure of elastic ?-conjugated molecular crystal for flexible organic photonics

Chuanxin Wei et al.

Summary: This study demonstrates the atomic-resolved structural perturbations of an elastic conjugated molecular crystal, achieving flexible naked-eye-visible and color-tunable afterglow wave guides. The outstanding elastic property of the crystal is derived from the synergistic effect of interlayer hierarchical slippage and intralayer molecule perturbations, allowing for the absorption and release of mechanical energy to avoid brittle fracture. The observations provide insights into the photophysical behavior of conjugated materials and the potential application of elastic crystals in flexible organic photonics.

Structural Origins of Elastic and 2D Plastic Flexibility of Molecular Crystals Investigated with Two Polymorphs of Conformationally Rigid Coumarin

Keke Zhang et al.

Summary: This study investigates the mechanical behaviors of two polymorphs of the structurally rigid molecule coumarin, revealing that form I crystals exhibit high elasticity while form II crystals are 2D plastic and twistable. The differences in mechanical behaviors are attributed to the molecular packing and interactions of coumarin rather than molecular flexibility.

Alternating Heterochiral Supramolecular Copolymerization

Michihisa Ueda et al.

Summary: In this study, a novel nonplanar-core monomer was used for polymerization, resulting in the formation of an alternating heterochiral supramolecular copolymer. The heterochiral copolymer displayed an alternating arrangement of H-bonded and polar p-stacked parts, which was found to be due to the effective cancellation of in-plane dipole moments between two thiophene amide moieties.

Photochromism of neutral spiropyran in the crystalline state at room temperature

Zhen Wu et al.

Summary: A solid-state optical switch based on the methanol-esterified spiropyran derivative S1 was successfully constructed in this study, demonstrating reversible photochromic properties without further recrystallization. The cultured single crystal (S1-C) unexpectedly exhibited photochromism at room temperature, indicating a rare example of neutral spiropyran crystal. The crystallographic analysis revealed that weak van der Waals forces dominate in the S1-C crystal, leading to loose packing and efficient photochromism.
