Summary: Two kinds of amorphous solid-state supramolecular systems with purely organic room temperature phosphorescence (RTP) were reported, which were activated by calix[3]phenothiazine (C[3]Pz) and 1,2-/1,3-dicyanobenzene (1,2-/1,3-DCB). The RTP of these supramolecular systems was entirely from the interaction between 1,2-/1,3-DCB and C[3]Pz, forming dense supramolecular complexes, leading to two different phosphorescence emissions. The use of 1,2-DCB and 1,3-DCB as molecular rivets fixed the C[3]Pz, inhibiting molecular vibration and reducing nonradiative relaxation, resulting in effective RTP emission with high quantum yields.

Summary: This study proposes a host-guest doping strategy to achieve both room-temperature phosphorescence (RTP) and flexibility in organic single crystals (OSCs). The flexible OSCs exhibit bright deep-red phosphorescence upon external force application and can return to their original shape after stress removal. The results suggest that the bright RTP is due to Forster resonance energy transfer (FRET) from the triphenylene molecules to the dopants. This strategy provides a simple and universal approach for the preparation of flexible OSCs with RTP.

Summary: The development of multifunctional luminescent materials is important but difficult due to different requirements for molecular structure in different luminescent properties. This study reported a universal exciplex platform to construct multifunctional luminescent materials, including thermally-activated delayed fluorescence (TADF), persistent room temperature phosphorescence (RTP) and mechanoluminescence (ML). The exciplex system, using compound PTZ-CN as an electron donor and its derivative of OPTZ-CN as an electron acceptor, showed efficient TADF with a quantum yield of up to 61%, persistent RTP lasting for more than 3 minutes, and bright blue ML emission. Thus, this work opens a new way for the construction of multifunctional luminescent materials, which will greatly promote further development in this research area.

Summary: The development of organic circularly polarized room temperature phosphorescence (CP-RTP) materials with tunable emission colors is a challenging issue. This study successfully constructs CP-RTP doped materials with green, yellow, and red afterglow by introducing chiral groups into three phosphors and using polyvinyl pyrrolidone as the host. The doped materials exhibit excitation-dependent and time-dependent RTP properties, providing an effective platform for constructing organic multicolor CP-RTP materials.

Summary: This study investigated the fluorescence/phosphorescence properties of 5-chloroindole embedded in poly (vinyl alcohol) films. The results showed that the fluorescence emission of 5-chloroindole was significantly quenched compared to indole, while the phosphorescence was twice as strong, indicating an increased intersystem crossing rate. Additionally, it was found that not only UV light but also longer wavelengths in the blue region could effectively populate the triplet state of 5-chloroindole and result in phosphorescence emission. This offers new possibilities for triplet state spectroscopy.

Summary: Coordination-driven self-assembly was utilized to construct two metallacycles using a dicarboxylate-functionalized dibenzo-18-crown-6 in combination with either a 0 degrees anthracene-based clip-type acceptor or a 60 degrees phenanthrene-based acceptor. The angularities of these components enabled the formation of a [2 + 2] rectangle and a [3 + 3] triangle, respectively. The synthesis, characterization, and host-guest chemistry of the two metallacycles were described and supported by 31P{1H}, 1H NMR spectra, and electrospray mass spectrometry.

Summary: We propose a facile strategy to achieve room-temperature phosphorescence in conventional hydrogels by polymerization-induced crystallization of dopant molecules, leading to clusterization-induced phosphorescence. Crown ethers dissolved in a concentrated acrylamide aqueous solution crystallize during polymerization to form large spherulites in the hydrogel, resulting in carbonyl clusters and phosphorescence emission. This strategy is universally applicable to hydrogels with different polymeric matrices and dopant molecules. The development of hydrogels with mechanical and phosphorescent properties holds great potential in the biomedical and engineering fields.

Summary: In this study, a room-temperature phosphorescence (RTP) system responsive to alkyl halides was described. The system consisted of a meta-formylphenyl-bearing pillar[5]arene derivative that supported effective through-space charge transfer. Treatment with bromoethane enhanced the emission. An isomeric para-formylphenyl-bearing pillar[5]arene system proved ineffective in producing an RTP effect.

Summary: Nonconjugated clusteroluminogens (CLgens), such as proteins and polystyrene, have become increasingly important in photophysics due to their advantages over traditional conjugated dyes in biological applications. However, their weak visible emissions in the aggregate state have hindered their development. This study proposes a strategy to construct a higher-level intramolecular through-space interaction (TSI) in multi-aryl-substituted alkanes, resulting in efficient clusteroluminescence (CL) with high luminescence quantum yield and long emission wavelength.

Summary: Despite the breakthrough of immunotherapy, immune checkpoint inhibitors often have low response rate and resistance towards solid tumors. A hypoxic tumor microenvironment provides tumor cells with high concentrations of HIF-1 and polyamines to evade immune cell destruction. Reprogramming the immunogenic microenvironment has shown promising results in boosting immunotherapeutic performances.

Summary: The integration of mechanically interlocked molecules (MIMs) into purely organic crystalline materials has been achieved using a dative boron-nitrogen bond-driven self-assembly strategy, resulting in the preparation of polyrotaxane crystals. The polyrotaxane structure of the crystalline material was confirmed by single-crystal X-ray diffraction analysis and cryogenic high-resolution low-dose transmission electron microscopy. The polyrotaxane crystals exhibit enhanced softness and greater elasticity compared to nonrotaxane polymer controls, attributed to the synergistic microscopic motion of the rotaxane subunits. This work highlights the importance of integrating MIMs into crystalline materials.
