Computational and experimental studies reveal that Group 4 tetroxides form a new type of σ-hole interaction with N and O nucleophiles, which we propose to name “titan bonds” (TnBs). These insights in...

Highly water-soluble dicationic bis(indolium) dyes have been prepared, showing excellent two-photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shi...

Thanks to the extra budget we received, the STSM tool is now open to PIs, members of the Action, who wish to visit a partner for a few days. Applications can be submitted continuously, before 1 Octob...

Controlling the self-assembly of dyes is essential for designing functional materials with tailored optical, electronic, and mechanical properties. However, achieving precise structures from two disti...

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.

We report the synthesis of novel ionic heteronuclear Pt(II)–Ag(I) complexes derived from Pt(NCN)-C≡CR precursors (R = aryl), where Ag+ ions coordinate to the acetylene groups. The photophysical invest...
