Summary: Developing a better understanding of the structure-property relationship of mechanochromic luminescent molecules is challenging. In this research, the authors demonstrate the impact of host-guest interactions on the mechanochromic properties of organic molecules. They observe bathochromic-shifted emission in a series of pyridinium-functionalized triphenylamine derivatives upon mechanical stimulation, which form homoternary host-guest inclusion complexes through charge transfer interactions. The study also involves a heteroternary complex that exhibits mechanochromic luminescent property. This work not only uncovers the effect of host-guest inclusion on mechanochromic properties, but also offers a principle and a simple approach to design sequentially red-shifted mechanochromic materials.

Summary: Guest/host phosphorescence materials with different molecular morphologies have been studied in this work, revealing that the morphology directly affects the phosphorescence properties. The guests form clusters in the host with strong intermolecular interactions for stabilizing triplet excitons, while hosts have weak intermolecular interactions to accept guest clusters, leading to excellent RTP properties in the doped materials.

Summary: The coordination-driven self-assembly methodology is a versatile synthetic tool for obtaining complex discrete structures such as interlocked, chiral, or heteroleptic cages. Efforts have been made to control host-guest affinity, particularly in targeting substrate transportation and releasing. Redox-stimulation offers novel possibilities for controlling the host-guest binding affinity and triggering guest release.

Summary: By using blend films, the ASE and luminescence performance of BUBD-1 were enhanced due to increased Stokes shift, energy transfer efficiency, and radiation attenuation rate. Analysis based on second-harmonic generation and angle-dependent PL spectra revealed changes in molecular dipole orientation in the films. The variation in molecular dipole angle in blend films contributed to the device properties.
