Abstract By a facile peripheral decoration of 5‐(4‐aminophenyl)‐10,15,20‐triphenylporphyrin (ATPP) with inherent aggregation‐induced emission (AIE) active tetraphenylethene (TPE), versatile AIEgenic porphyrin derivative (ATPP‐TPE) was obtained, which greatly abolishes the detrimental π–π stacking and thus surmounts notorious aggregation‐caused quenching (ACQ) effect ATPP in aqueous phase. The photoluminescence ATPP‐TPE is 4.5‐fold stronger than at aggregation state. Moreover, an unequivocal...
Porphyrins easily aggregate due to unfavorable π-π accumulation, causing luminescent quenching in the aqueous phase and subsequently reducing efficiency. It is a feasible way immobilize porphyrin molecules through metal–organic framework materials (MOFs). In this study, 5,10,15,20-tetrakis (4-carboxyphenyl) (TCPP) was introduced into skeleton (PCN-224) as ligand. The result showed that electrochemiluminescence (ECL) photoluminescence (PL) efficiency of MOF 8.2 6.5 times higher than TCPP,...
Abstract The precisely modulated synthesis of programmable light‐emitting materials remains a challenge. To address this challenge, we construct four tetraphenylethylene‐based supramolecular architectures (SA, SB, SC, and SD), revealing that they exhibit higher electrochemiluminescence (ECL) intensities efficiencies than the tetraphenylethylene monomer can be classified as highly efficient intramolecular aggregation–induced (PI‐AIECL) systems. best‐performing system (SD) shows high ECL...
Sulfurized polyacrylonitrile (S@PAN) composites have gathered a lot of interest because their advantages high theoretical energy density, excellent cycling stability, and environmental friendliness. Meanwhile, unique "covalent bonding" mechanism effectively avoids the dissolution shuttling polysulfides, thus they are expected to be most promising candidate for cathode material in lithium-sulfur (Li-S) batteries. Over past five years, S@PAN materials been widely studied Li-S batteries, it is...

The conversion of carbon dioxide to fuels, polymers, and chemicals is an attractive strategy for the synthesis high-value-added products energy-storage materials. Herein, density functional theory method was employed investigate reaction mechanism CO2 hydroboration catalyzed by manganese pincer complex, [Mn(Ph2PCH2SiMe2)2NH(CO)2Br]. carbonyl association dissociation mechanisms were investigated, calculated results showed that more favorable with energetic span 27.0 kcal/mol. Meanwhile,...
The development of superior probes is highly desirable and valuable for viscosity measurement. Herein, we designed reported a series diphenylbenzofulvene (DPBF)-based organic luminophores according to the molecular regulation strategy. There are two free-rotating phenyl groups attached rigid fluorene skeleton in DPBF, enabling its unique propeller-like noncoplanar chemical structure. Benefiting from this, DPBFs could feature outstanding PL ECL emissions with intriguing aggregation-induced...
Electrochemiluminescence (ECL) analysis stands out among various analytical methods due to its exceptional sensitivity and accuracy. However, the poor solubility of most ECL probes limits their effectiveness in aqueous environments. To address this challenge, we developed a water-soluble anion-π+ luminophore, DPBC-OTS. With remarkable water electron transfer characteristics, study detailed revealed that DPBC-OTS exhibited excellent performance infrared region. Additionally, leveraging ion...
For optimal energy transfer in self-luminous lanthanide metal-organic frameworks (Ln-MOFs), the of lowest triplet excited state must align with ideal levels. Failure to meet this condition can lead reverse transfer, reducing luminous efficiency. In study, we developed a mixed-ligand MOF, Eu-TCPP-BOP, which exists as an ECL self-enhancing luminophore. We used SPECM study role boron ligands bridge for electron transport improving performance Eu-TCPP. The H4TCPP and 5-BOP act donor shuttle,...
