Summary: Stimuli-responsive luminogens with aggregation-induced emission and excited state intramolecular proton transfer (ESIPT) properties have a wide range of applications. In this study, a simple pressure-induced method was used to restrict the twisted intramolecular charge transfer (TICT) behavior, resulting in fluorescence enhancement and color shifts under high pressure. The inhibition of TICT was achieved by damaging the ESIPT process and restricting the rotation of a specific molecule. This approach offers a new strategy for the development of stimulus-responsive materials.

Summary: Novel BF2-beta-diketonate complexes 1-4 with phenylboronic acid moieties and methoxyphenyl or dimethylaminophenyl groups were synthesized and their photophysical properties, pH response, and reactivity to D-fructose were evaluated. Complexes 1 and 2 with a methoxyphenyl group exhibited high intensity luminescence in non-polar to polar solvents, except in DMSO, while complexes 3 and 4 with a dimethylaminophenyl group showed a significant decrease in luminescence intensity with increasing solvent polarity due to twisted intramolecular charge transfer (TICT) properties. The luminescence intensity of complexes 1 and 2 decreased with increasing pH but increased when reacted with D-fructose due to intermolecular vibration and suppression of intermolecular vibration, respectively, whereas the luminescence intensity of complexes 3 and 4 increased with both increasing pH and reaction with D-fructose due to the loss of TICT properties. The photophysical properties of complexes 1-4 and the TICT properties of complexes 3 and 4 were supported by density functional theory calculations.

Summary: In this study, triphenylamine-based carbon dots (T-CDs) with intramolecular charge transfer (ICT) and aggregation-induced emission (AIE) were synthesized in acetic acid. The T-CDs exhibited different fluorescence colors in solvents with different polarities, and aggregation occurred in the presence of water. The increasing aggregation resulted in bright red emissions as a result of ICT and AIE. Interestingly, the T-CDs can be used for intracellular imaging and lysosome-specific targeting of live cells.

Summary: A pyrido[3,2-g]quinoline derivative named LA17b was synthesized for efficient photoelectric organic materials construction. The molecule exhibits pronounced red-shift in fluorescence spectra with increasing solvent polarity, but without fluorescence quenching due to twisted intramolecular charge transfer (TICT) state. In ethanol, LA17b shows a highly emissive TICT state with long fluorescence lifetime, playing a crucial role in enhancing intersystem crossing rate. The optical properties suggest LA17b as a promising candidate for optoelectronic applications.

Summary: This study investigates the effect of impurities on the voiding propensity in SnAgCu and Ni-containing SnAgCu alloys solder joints with Cu under thermal aging. Results show that high levels of impurity incorporation lead to significant void propagation, but controlling the additive formulas can weaken the impurity effect and suppress the void propagation effectively. The weakening phenomenon of the impurity effect is more pronounced in the SnAgCu-Ni/Cu joint, indicating that Ni addition helps reduce the influence of impurities.

Summary: Chemical structures with aggregation-induced emission enhancement (AIEE) and intramolecular charge transfer (ICT) properties have attracted the attention of researchers. In this study, we designed and synthesized a series of fluorophores with tunable AIEE and ICT properties by adjusting the medium polarity. We investigated the optical properties and self-assembly abilities of these molecules and observed different nanostructures and spectral changes by adjusting the water ratio in mixed solutions. The results show that the AIEE comes from the formation of micelle-like nanoaggregates, leading to a blue-shift in emission and enhanced intensity.

Summary: The growth of intermetallic compound (IMC) was investigated in the solid/solid state reaction between Sn-9 wt.% Zn (SZ) and Cu-3.28 wt.%Ti (C1990 HP), Cu-2.0 wt.% Be (Alloy 25), and Cu-2.3 wt.% Fe (C194) alloys at temperatures of 125-175 degrees C for 100-2000 h. The formation of CuZn5 and Cu5Zn8 phases was observed in the SZ/C1990 HP couples, with a transformation from CuZn5 to Cu5Zn8 as the aging temperature and time increased. In the SZ/Alloy 25 couples, both CuZn5 and Cu5Zn8 phases formed without any phase transformation. Only the Cu5Zn8 phase formed at the early stage of aging in the SZ/C194 couples. The formation of Cu-Sn IMC was promoted at higher temperatures and longer aging times due to Sn tunneling phenomena.

Summary: This study compares the suppression effect of two organic additives on copper electrodeposition. The results show that EPE2900 exhibits better suppression efficacy and negligible impurity residues in the copper layer. The Sn/Cu solder joint constructed by EPE2900 has high micro-structural stability and no propagation of detrimental voids during isothermal aging. The better suppression efficacy and negligible impurity residues of EPE2900 can be rationalized based on quantum chemical calculations.
