Exciton diffusion and hole transfer play crucial roles in the efficient generation of charge carriers in organic photovoltaic systems. The precise manipulation of this carrier generation mechanism has been successfully realized through the ternary approach of creating acceptor alloys within the donor-acceptor system. The incorporation of this acceptor alloy has proven to significantly decrease the trap density within the system, enhancing overall efficiency. More details are discussed in the article by Hao et al. on pages 1275—1283.

Exploiting chirality transfer between achiral building blocks and chiral induced reagents (CIR) is important to construct chiral metal-organic frameworks (MOFs). Here, achiral tetradentate ligands with intrinsic spontaneous resolution can form the absolute configuration through chiral induction. Conversely, the nonchiralization of CIR causes the disappearance of symmetry breaking of tetradentate ligands. These results are meaningful to develop chiral crystal engineering of MOFs. More details are discussed in the article by Ma et al. on page 1260—1266.

Twisted Phosphors that Violate Kasha's Exciton Model in Organic Systems

A twisted organic difluoroboron β-diketonate phosphor possessing intramolecular charge transfer character and flexible molecular structure was doped into different organic matrices to fabricate phosphorescence materials. The twisted phosphor adopts different conformation in different matrices. Consequently, the dopant-matrix systems break T1 energy conservation and exhibit distinct phosphorescence wavelengths, violating Kasha's exciton model.

Chlorajaponins A—Q, Lindenane-Related Sesquiterpenoid Dimers from Chloranthus japonicus and Their Biological Activities

Seventeen new lindenane sesquiterpenoid dimers (LSDs), chlorajaponins A—Q (117), including two rearranged skeleton meroterpenoids (12), and 13 reported analogs (1830) were isolated from the Chloranthus japonicus Sieb. Compounds 1, 2, and 18 demonstrated significant inhibitory effects on lipid accumulation, dose-dependently reduced TG and TC levels, and significantly downregulated expression of FASN and SERBP1 validated by western blot assay. Moreover, compounds 1922 and 25 exhibited the most potent anti-inflammatory effects with IC50 values of 7.89, 6.25, 2.98, 10.77, and 3.60 μmol/L, respectively.

Chiral induction agent can control the formation of the absolute configuration of racemate ligands. Two pairs of homochiral metal-organic frameworks (MOFs) were synthesized with the presence of enantiopure camphoric acid (D/L-cam). Importantly, DCF-17 and LCF-17 exhibit the efficient circularly polarized luminescent (CPL) activity with a luminescence dissymmetry factor (glum) value of –1.0 × 10–2 and +9.2 ×10–3, respectively.

Controllable Exciton Diffusion Length and Ultrafast Charge Generation in Ternary Organic Solar Cells

This work demonstrates the feasibility of regulating exciton diffusion and hole transfer to promote efficient charge generation, and achieving high-performance OPV devices by increasing short-circuit current density. Fast and efficient charge generation requires an increased exciton diffusion length and faster hole transfer. In addition, the reduced trap state in the ternary system is also beneficial for reducing recombination of charges. This work reveals the co-mechanism of charge generation and trap state on JSC.
