Summary: Pure organic mechanoluminescent materials are environmentally friendly and can be mechanically stimulated by external force. By strengthening intermolecular C-Hπ interactions in the ML-inactive thioxanthene derivatives TxPh, a new compound TxPhTh with bright mechanoluminescence was obtained. The enhanced C-Hπ interactions suppressed non-radiative transition channels and increased the photoluminescence quantum yield of crystalline TxPhTh. This research provides a new approach for designing mechanoluminescent materials and advances the understanding of their mechanism.

Summary: In contrast to neutral cocrystals, designing ionic cocrystals, especially those with an ion pair, is challenging. Previous studies that correlate specific molecular properties to cocrystal formation generally exclude ionic cocrystals, leaving few clear avenues to success for prospective ionic cocrystal engineers. In this study, ammonium nitrate was targeted for cocrystallization with a potential coformer group selected based on likely interactions with the nitrate ion. Six novel ionic cocrystals were discovered, and a high packing coefficient was found to be a consistent feature among successful coformers.

Summary: This study presents a rational strategy to activate wide-color ranged and persistent room-temperature phosphorescence (RTP) from amorphous films by embedding electron-rich organic phosphors into an electron-deficient matrix polyacrylonitrile (PAN). The ultralong lifetime of 968.1 ms was obtained for the doped film TBB-6OMe@PAN through tailoring noncovalent interactions between the electron-deficient PAN matrix and electron-rich organic phosphors, indicating the activation of persistent RTP may be triggered by strong electrostatic interactions between the two components. Further theoretical calculations demonstrated that both electrostatic and dispersion interactions are responsible for the activation of persistent RTP in the doped films, with the doped film also showing excellent water resistance after 12 weeks.

Summary: This study focused on the different optical properties resulting from different molecular packing modes in aggregates. The two polymorphs of DBTDO-DMAC exhibited distinct properties, with one showing mechanochromism and the other displaying room-temperature phosphorescence. Careful analyses revealed that the emissive behaviors are highly related to the molecular conformation and packing modes, providing guidance for designing other luminogens with similar properties.

Summary: The co-crystallization of tetracyanobenzene with haloarenes was studied, and it was found that the stacking interactions and lone pair-pi-hole bonds between the molecules promote the strength of halogen bonding. The stacking interactions increase the ability of haloarenes to act as halogen bonding donors.

Summary: Molecular recognition based on noncovalent bonding is important in directing supramolecular phenomena. Weakly associated recognition motifs are challenging to identify and investigate. This study synthesized a [2]catenane compound to enhance weak interactions and reduce system complexity. By using this compound as a model, three possible binding modes between CBPQT and BIPY were discovered and characterized. These findings have potential applications in self-assembled materials and supramolecular catalysis.

Summary: In this study, a new family of benzothiazole-enolate-based organoboron luminophores (HN1-4) with efficient dual-phase emission was constructed. HN4 exhibited one of the highest quantum yields among similar compounds. The intense emission in the solid state was attributed to the twisted core structure constructed by the boronic coordination of two penta-fluorobenzene in HN4. Additionally, HN4 showed a unique response to mechanical force accompanied by a reversible change of the quantum yield.

Summary: In this study, a new type of donor-sigma-acceptor emitter that exhibits thermally activated delayed fluorescence (TADF) is demonstrated for the first time, with sulfobenzimide moiety used as an acceptor unit. The emission of the synthesized compound in different solutions can be attributed to either locally excited carbazole moiety or trough-space charge transfer (exciplex-like) between carbazole and sulfobenzimide units. In the solid state, aggregation-induced emission enhancement and different emission colors are observed due to different conformations. The mechanoluminescence and electroluminescence properties of the compound are extensively studied, and the compound shows good performance as a non-doped TADF emitter in organic light-emitting diodes fabricated on different substrates.

Summary: This research develops a host-guest energy transfer relay strategy to improve the phosphorescence lifetime of multi-twisted luminophores, achieving persistent room-temperature phosphorescence (pRTP) that is visible to the naked eye. Additionally, photoexcitation-induced molecular rearrangement is used to further prolong the phosphorescence lifetime. This work is significant in advancing our understanding of molecular photophysical mechanisms and guiding the study of molecular systems that are difficult to achieve pRTP.

Summary: Photodriven self-assembly is a crucial strategy to regulate the molecular orderliness and structure. While traditional photochemical self-assembly has disadvantages, physical processes based on photoexcitation can fully utilize photons to avoid drawbacks. These processes drive molecular movement and aggregation, promoting the assembly of materials. The exploration of photoexcitation-induced assembly can lead to the development of unprecedented optoelectronic materials.

Summary: A pyrrolylmethylene appended corrorin 1 was synthesized and coordinated with [Rh(CO)2Cl]2 to form 1-Rh with unique RhI-eta 2-CC bonding. Further oxidation of 1 yielded 2, which exhibited a hydrocorrorinone core and could be transformed into pyrrolo[3,2c]pyridine derivative 3. The reactivity of corrorin and the near-infrared (NIR) absorption of the resulting porphyrinoids were effectively modified by the side chain.

Summary: In this work, we investigated the electronic states in a series of TADF exciplexes formed with TpBpTa and various hole-transporting compounds. We explained the photophysical behavior of these exciplexes using computational methods and found that the temporal red shift in the time-resolved spectra is related to the distribution of molecular conformations and CT energy in the film. We also studied the trapping phenomena in exciplex blends using spectrally resolved thermoluminescence measurements and found that trapped charge carriers recombine through the luminescent intermolecular CT state.

Summary: Proton donating ability is crucial in chemical, physical, and biological processes. However, there is a lack of suitable models for quantitative visualization. In this study, fluorescent chemoprobes based on ortho-pyridinyl anilines were synthesized, and their fluorescence signal showed a quantitative relationship with intermolecular hydrogen bond strength. This allowed for the quantification of the proton donating ability of external proton donors through competitive hydrogen bond formation.

Summary: The development of emissive materials for OLEDs is an important research field. The efficiency of triplet-to-singlet exciton conversion is crucial. Thermally activated delayed fluorescence (TADF) is the most efficient method for this conversion. In this paper, donor-acceptor materials based on 2-pyridone acceptor coupled to different donor moieties were studied, showing good performance in various OLEDs. Despite low photoluminescence quantum yields, these compounds demonstrated high efficiency in OLEDs due to the hot exciton approach.

Summary: Concerted companion (CC) dyes have been developed by linking the donors of porphyrin and organic dye units. The DSSCs based on the CC dyes XW85 and XW86 show higher J(SC) and PCE compared to the corresponding cosensitization systems. However, the PCEs for XW85 and XW86 are still lower than that of the acceptor-linked reference dye XW76. The study suggests that longer linking chains and avoidance of unfavorable alignments can improve the photovoltaic behavior of CC dyes.

Summary: Although tris(8-hydroxyquinolinato) aluminum (Alq(3)) and its derivatives are widely used in organic lighting devices, the use of metal-free 8-hydroxyquinoline is impractical due to rapid proton transfer. In this study, the problem of proton transfer and vibrational quenching was overcome by complexation and organization of 8-hydroxyquinolinium cations into a solid network with appropriate counter-anions. The resulting compounds showed superior photoluminescence and thermal stability compared to Alq(3) and related materials.
