Summary: This study reported the synthesis of unprecedented β,β-directly linked cyclic zinc porphyrin oligomers, the trimer (CP3) and tetramer (CP4), through Yamamoto coupling of a 2,3-dibromoporphyrin precursor. The three-dimensional structures of CP3 and CP4 were confirmed by various analytical techniques. CP3 exhibited a propeller shape while CP4 had a saddle shape, resulting in different photophysical and electrochemical properties. CP4 also showed affinity for fullerenes, forming complexes with C70 and C60 in toluene solution.

Summary: Research on porphyrin-based photosensitizer system is of great theoretical and practical significance in photodynamic therapy (PDT) for cancer treatment. In this article, a series of porphyrin derivatives were designed and synthesized, leading to the construction of a push-pull porphyrin photosensitizer with two symmetrical ethanethioate groups. Through characterization and theoretical analysis, the relationship between porphyrin structure and properties was revealed. The synthesized porphyrin compounds demonstrated high singlet oxygen generation and low dark toxicity under long-wavelength light.

Summary: A series of novel porphyrins with tetra-meso-thien-2-yl groups were synthesized, and their photophysical properties were studied. Various techniques were used to investigate the electronic communication between the central Zn(II) porphyrin ring and different meso-substituent groups. The effect of the position and number of thienyl rings on the properties of these porphyrins was compared to zinc tetraphenylporphyrin (ZnTPP). The photochemically-driven antimicrobial activity of zinc(II)-5,10,15,20-tetra(thien-2 '-yl)porphyrin (ZnThPP) as a coating against both Gram-positive and Gram-negative bacteria was determined and compared to ZnTPP. Visible irradiation resulted in significant antimicrobial response.

Summary: The non-covalent donor-acceptor structure composed of ZnTCPP and C60-EDA showed improved separation of photogenerated excitons, resulting in enhanced photocatalytic performance for H2 evolution. The efficient electron transfer channel between ZnTCPP and C60-EDA contributed to the charge separation and faster migration of charge-carriers. The photocatalytic activity of ZnTCPP/C60-EDA for H2 evolution was 113.5 mu mol h-1, which was 3.9 times higher than that of pure ZnTCPP. This work provides valuable insights into non-covalent D-A construction for enhanced photocatalysis.

Summary: This study investigates the mechanofluorochromic behavior of microcrystals and nanostructures using atomic force microscopy (AFM). It is found that the red light photoluminescence of these materials can be turned on by contact AFM, with the intensity of light emission linearly correlated to the applied force. Recovery is associated with a decrease in emission intensity, which can be reactivated by subsequent contact scans.

Summary: In this study, we synthesized two different bichromophoric difluoroboron-beta-diketonate compounds with different connectivity using cyclohexane diamine as a chiral bridge. TD-DFT calculations and experiments revealed that the connectivity variation affects the spatial arrangement and chirality inversion of the compounds. The compound with para connectivity showed higher absorption values, and ultrasonication and heating induced the formation of highly ordered nano-helical wires, leading to increased emission values.

Summary: This article highlights the importance of using fluorescent nanocrystals for biosensing, particularly colloidal quantum dots (QDs) which can perform resonant energy transfer (FRET). The study reveals that unlike molecular fluorophores, the emission properties of QDs are highly dependent on their size distribution, leading to energy transfers between QDs when clustered together. A mathematical model is developed to explain the efficiency of this homogeneous resonant energy transfer (homo-FRET) process, which is influenced by the statistical donor-acceptor polarization of the QD population.

Summary: This article describes a tetrazine derivative that exhibits color-tunable crystals upon external stimuli. By heating and cooling processes, Bis(4-methylphenoxy)tetrazine (1) forms crystalline phases with photoluminescence color transitions ranging from green to red. These thermoresponsive polymorphisms and colors can be reversibly recovered by solvent vapor annealing. Additionally, the unique T-shape arrangement of the tetrazine rings and the phenyl rings leads to the formation of flexible crystals.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
