Summary: Research on an almost non-fluorescent merocyanine dye equipped with large solubilizing substituents revealed insights into its aggregation behavior and fluorescence properties. Concentration-dependent UV/Vis spectroscopy showed a two-step anti-cooperative aggregation mechanism, forming dimers and decamer stacks. The dye aggregates exhibited a strong AIEE effect, with excimer-type fluorescence and aggregation-induced CPL enhancement.

Summary: This study demonstrates a one-pot strategy for the molecular design of stimuli-responsive luminescent polymers, incorporating N,N-dimethyl moieties to achieve both stimuli-responsive and red-shifted nonconjugated emission properties. The prepared polymers show intriguing substitution position related structure-property relationships and potential applications in explosive detection and luminescent encryption.

Summary: This study investigates the strategy of tuning phase separation morphology in polymer blend thin films by controlling the number of blocks in linear copolymers. It is verified that multiblock copolymers are more effective in reducing the size of phase separation domains compared to diblock copolymers. Simulation results show that the compatibilization behaviors of diblock and multiblock copolymers differ.

Summary: Self-assembly of dilute sequence-defined macromolecules is a complex phenomenon with a dependence on the sequence. In this study, supervised machine learning was used to accurately predict the morphology of aggregates formed by these macromolecules. High-throughput screening was also demonstrated to identify suitable sequences for self-assembly.

Summary: In this study, innovative PET materials with strong luminescence were successfully synthesized by doping PET with silicon-linked poly(ethylene glycol)-PET copolymer nanostructures. The hybrid materials were characterized and the composites were prepared to study their properties. The results showed that the addition of ETP@Si-PEG-PET at 0.75 wt% significantly improved the crystallinity, tensile strength, and fluorescence intensity of PET.

Summary: Mono-/diboron complexes with saddle-shaped molecular conformations were synthesized from porphyrins(2.1.2.1). The boron complexes exhibit unique structure-dependent photophysical properties, with diboron complex 3b showing aggregation-induced emission (AIE) in the deep-red region, which is the first case of boron porphyrinoid complex showing AIE emission in decades.

Summary: This work focused on the design and synthesis of deep-red emitting BODIPY dyes with high emission quantum yields. Introducing aromatic rings and the electron-withdrawing group -CF3 into the BODIPY structure successfully shifted the emission wavelength to 626 nm in the deep-red region with a high quantum yield of 0.99. However, modifying the meso-C of BODIPY with CF3 quenched its emission.
