Summary: In this study, a water-soluble PDI cyclophane Gemini Box (GBox-1(4+)) was developed, which effectively eliminated the self-aggregation of PDIs and could be used for lysosome-targetable live-cell imaging. Furthermore, GBox-1(4+) stabilized the highly concentrated aqueous solution of PDI radical anion, leading to excellent near-infrared photothermal effect for efficient and selective antibacterial applications.

Summary: This study focused on the experimental and theoretical characterization of photophysical properties and photodegradation of newly obtained boron-dipyrromethene (BOPIDY) derivatives for biomedical applications. The results showed that exposure to UV light caused changes in absorption bands, leading to photodegradation over time.

Summary: Pyrazine-decorated benzotriazole cores allow the orthogonal combination of two dipolar systems within a single molecule. The photophysical features of these derivatives showed remarkable differences depending on the substitution in the pyrazine ring of the benzotriazole core. Furthermore, these compounds exhibited good two-photon absorption properties, and TD-DFT calculations supported the experimental observations.

Summary: This article utilizes density functional theory (DFT) and time-dependent density functional theory (TDDFT) to study a series of quinquethiophene compounds functionalized with S,S-dioxide and side alkyl chains. It successfully reproduces the experimental UV-Vis absorption and fluorescence emission spectra and provides insight into the effects of sulfur di-oxidation and side chain engineering on the absorption and fluorescence of oligothiophene.

Summary: This study investigates the nonlinear optical limiting (OL) property of tin phthalocyanine porous organic frameworks (Sn-Pc-POFs) dispersion in the nanosecond regime. The results show that the material has excellent dispersibility, stability, and a low OL threshold. To explain the nonlinear optical response mechanism, the energy level structure of Sn-Pc-POFs was simulated and the photoinduced carrier dynamics were studied. The study reveals that the material's excellent OL property is attributed to its large absorption cross section and long excited state lifetime.

Summary: By incorporating perylene into an inorganic-organic hybrid film, a highly photoluminescent material was achieved. Modification of octosilicate with a cationic surfactant allowed for molecular and uniform accommodation of perylene. Near-unity photoluminescence quantum efficiency was attained in hybrids with a high concentration of perylene.

Summary: Two novel fluorescent probes (P1 and P2) containing a perylene tetra-(alkoxycarbonyl) derivative (PTAC) and its copper chelate were designed and synthesized. The probes showed high selectivity and sensitivity towards fluoride ions, with their sensing mechanism involving the formation of H-bond between the O-H moiety and fluoride ions. The coordination of copper ion enhanced the H-bond donor capacity of the receptor unit (O-H).

Summary: The discovery of the self-assembly of cyanine dyes into J-aggregates had a significant impact on dye chemistry, leading to the emergence of new useful properties. Despite a good theoretical understanding of their structure-property relationships, examples of J-aggregates remained scarce due to the lack of supramolecular designs to guide their formation. The use of nature's supramolecular blueprint in the development of J-aggregates of perylene bisimides (PBIs) has shown promise in various applications, such as high-performance color pigments and organic semiconductors.
