Summary: In this study, we describe the self-assembly of a tetraphenylethylene (TPE) derivative with amino acid substitution into a hydrogen-bonded dimeric capsule. Depending on the conditions, the TPE derivative exhibits bluish photoluminescence with QYs up to 24% due to the AIE effect and excimer formation.

Summary: By using multi-component emissive metallacages as solid-state fluorescent materials, high quantum yield emission performance was achieved by restricting molecular motions and suppressing non-radiative decay. One of the metallacages exhibited very high fluorescence quantum yield in the solid state and was successfully applied as a coating for white-light emission in a blue LED bulb.

Summary: Utilizing nonplanar conjugated molecules for self-assembly is challenging but important. In this study, the self-assembly process of a nonplanar conjugated molecule with aggregation-induced emission (ALE) feature was demonstrated, driven by amphiphiles. The superhigh aggregation-sensitive emission provided precise information about the self-assembly process. The arrangements of ALE-active molecules changed from disordered to well-organized forms by reducing the twisted configuration. The obtained vesicles showed superhigh thermal stability and promising light-harvesting applications.

Summary: This study demonstrates the synthesis of simple and tunable hydrophobically driven chiral functional assemblies of diacetylene cored pseudopeptides. The chiral appended amino acid elements and the hydrophobic dialkyne core play important roles in the self-assembly and aggregation induced emission properties of these materials. Moreover, these supramolecular materials show promising applications in inducing chirality into non-chiral liquid crystal matrices.
