Organic donor–acceptor (D–A) cocrystals are gaining attention for their potential applications in optoelectronic devices. This study explores the dynamics of ch

Polar organic cocrystals hold significant promise for various advanced technological applications. However, their relatively low occurrence emphasizes the difficulties in achieving the desired polar p...

Hydrogen bond pairing and supramolecular synthon approaches have influenced the understanding of cocrystal formation for decades, but whether or not hydrogen bonds are the dominant interaction in cocr...

Mechanochemical approaches to the preparation of chalcogen-bonded cocrystals have not been systematically well-studied. We report here the preparation of six cocrystals and salt cocrystals of chalcoge...

Noncovalent interactions, such as halogen bonding (HaB) and π-stacking, play a pivotal role in directing supramolecular assemblies and tuning photophysical properties. Herein, we report the synthesis, X-ray structural characterization, and photophysical properties of cocrystals and host:guest adducts formed by iodopentafluorobenzene (G) with three distinct Pt(II) complexes (1–3). The cocrystals exhibit a combination of short I···Pt halogen bonds and π-hole···Pt interactions in the solid state, highlighting the dual role of the Pt(II) center as a halogen bond acceptor and a π-stacking participant. Interestingly, an enhancement in emission intensity is observed for complexes 1·G and 2·G upon mixing of 1 or 2 with G in a chloroform solution, attributed to synergistic σ-hole···[dz2-PtII] interactions that reduce the flexibility of the square-planar complex and the double heavy atom effect. These results emphasize the potential of host:guest interactions as a strategy for enhancing luminescence efficiency and open new avenues for designing functional materials for sensing and optoelectronic applications.

The solid lithium-ion electrolytes (Adpn)2LiXF6 (Adpn = adiponitrile, X = P, As, Sb) are isomorphic salt-solvate cocrystals with slight differences in lattice spacing (<0.15 Å). The Li+ cations are co...

We demonstrate positional control of noncovalent σ- and π-hole interactions through strategic isomeric positioning of iodine substituents in selanes p-IC6F4SeC6F5 (1), m-IC6F4SeC6F5 (2), and o-IC6F4Se...

This study systematically investigates the supramolecular assembly of iodoselanes (organoselenenyl iodides of the general type ArFSeI, where ArF is a perfluoroaryl group) bearing different terminal pe...
