“…The weak absorption peak at 280 nm is the Soret band, which specifically is the S0→S2 B band transition in the Goutterman orbital model. [55] The strong absorption peak at 486 nm is the Q band transition from S0 to S1. SubPc-Br/UiO-66 (1:75) showed a strong absorption peak at 566 nm, indicating that UiO-66 was successfully coupled with SubPc-Br and that the supramolecular SubPc-Br/UiO-66 array is a potential visiblelight-induced photocatalyst.…”

“…[49,[52][53] Secondly, this unique structure exhibits abundant aromatic ring 𝜋-stacking and hydrogen bonds, allowing the dynamic formation of stable supramolecular arrays in the form of intramolecular dimers. [54][55][56] These existing van der Waals forces and hydrogen bonds effectively prevent reverse electron transfer, thus ensuring consistent catalytic activity. [57][58][59][60] It is worth noting that there is no report on the self-assembly of organic supramolecular arrays onto MOFs to construct S-scheme heterostructures, as well as their applications.…”

Constructing heterojunction of supramolecular arrays self‐assembled on metal–organic frameworks (MOFs) with elaborate charge transfer mechanisms is a promising strategy for the photocatalytic oxidation of organic pollutants. Herein, H12SubPcB–Br (SubPc–Br) and UiO‐66 are used to obtain the step‐scheme (S‐scheme) heterojunction SubPc–Br/UiO‐66 for the first time, which is then applied in the photocatalytic oxidation of minocycline. Atomic‐level B–O–Zr charge‐transfer channels and van der Waals force connections synergistically accelerated the charge transfer at the interface of the SubPc–Br/UiO‐66 heterojunction, while the establishment of the B–O–Zr bonds also led to the directional transfer of charge from SubPc–Br to UiO‐66. The synergy is the key to improving the photocatalytic activity and stability of SubPc–Br/UiO‐66, which is also verified by various characterization methods and theoretical calculations. The minocycline degradation efficiency of supramolecular SubPc–Br/UiO‐66 arrays reach 90.9% within 30 min under visible light irradiation. The molecular dynamics simulations indicate that B–O–Zr bonds and van der Waals force contribute significantly to the stability of the SubPc–Br/UiO‐66 heterojunction. This work reveals an approach for the rational design of semiconducting MOF‐based heterojunctions with improved properties.

“…Furthermore, it has been proved that sensitization method can effectively improve the photocatalytic activity of TiO 2 , especially when the sensitizer is macrocyclic conjugated structurally related such as phthalocyanines (Pcs) and porphyrins. [41] At present, a wide variety of Pcs and porphyrins have been used in the field of dye-sensitized photocatalysis, such as photocatalytic degradation of pollutants, [42][43][44][45] photocatalytic water splitting for hydrogen production, [46] and photocatalytic CO 2 reduction, [47] and showed excellent performance. Subphthalocyanines (SubPcs), which is a lower homologue of phthalocyanine species and the one of the most striking characteristics is the cone-shaped structure by comparison with an extensive range of macrocyclic and planar aromatic compounds.…”

Utilizing subphthalocyanine (SubPc) and 4,4 0 -dihydroxybiphenyl (C 12 H 10 O 2 ) as the raw materials, an innovative axial substituted SubPc H 12 SubPcB-OPh 2 OH was synthesized by solvothermal method. The density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were employed to further study the properties and structures of H 12 SubPcB-OPh 2 OH. To expand photocatalytic activities for organic dyes degradation, H 12 SubPcB-OPh 2 OH was decorated onto surface of TiO 2 nanoparticles to fabricate high-efficiency H 12 SubPcB-OPh 2 OH/TiO 2 photosensitive catalysts. The degradation experiments indicated that the H 12 SubPcB-OPh 2 OH/TiO 2 catalyst with the mass ratio of 1:25 had the greatest performance in the elimination of methyl orange (MO), bromophenol blue (BB), methylene blue (MB), and acid fuchsin (AF). The 29.4%, 72.5%, 27.6%, and 64.8% of MO, BB, MB, and AF was removed by pure TiO 2 in 180-min, respectively. Under the same conditions, the photocatalytic rate of H 12 SubPcB-OPh 2 OH/TiO 2 can reach 96.3%, 99.5%, 97.5%, and 99.5%, separately. The efficiency of the as-synthesized composite was 3.3, 1.4, 3.5, and 1.5 times higher than that over bare TiO 2 for MO, BB, MB, and AF degradation under visiblelight irradiation, respectively. Besides, after five cycles of experiments, the degradation rate of H 12 SubPcB-OPh 2 OH/TiO 2 photocatalyst to BB can still reach 90.2%, which demonstrated that the obtained photocatalysts possessed remarkable stability and is much higher than 15.6% of pure TiO 2 . This study provides a new idea to the construction of photosensitive catalysts based on TiO 2 for water purification.
