The title compound, CHNO [systematic name: 2,6-di-benzyl-pyrrolo-[3,4-]iso-indole-1,3,5,7(2,6)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal benzyl groups at the N-atom positions. The mol-ecule is located about an inversion centre, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, both terminal phenyl groups, tilted by 72.97 (4)° with respect to the mean plane of the central pyromellitic di-imide moiety (r.m.s. deviation = 0.0145 Å), are oriented away from each other, forming an elongated S-shaped conformation. In the crystal, mol-ecules are connected weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions, resulting in the formation of supra-molecular layers extending parallel to the plane.

The development of redox-conductive metal-organic frameworks (MOFs) and the fundamental understanding of charge propagation through these materials are central to their applications in energy storage, electronics, and catalysis. To answer some unresolved questions about diffusional electron hopping transport and redox conductivity, mixed-linker MOFs were constructed from two statistically distributed redox-active linkers, pyromellitic diimide bis-pyrazolate (PMDI) and naphthalene diimide bis-pyrazolate (NDI), and grown as crystalline thin films on conductive fluorine-doped tin oxide (FTO). Owing to the distinct redox properties of the linkers, four well-separated and reversible redox events are resolved by cyclic voltammetry, and the mixed-linker MOFs can exist in five discrete redox states.

Minimizing Voltage Losses via Synergistically Reducing Hetero-Interface Energy Offset for High Efficiency Perovskite Solar Cells.

Small

August 2024

State Key Laboratory of Alternate Electrical Power System with Renewable Energy Sources, School of New Energy, North China Electric Power University, Beijing, 102206, China.

The open circuit voltage (V) losses at multiple interfaces within perovskite solar cells (PSCs) limit the improvements in power conversion efficiency (PCE). Herein, a tailored strategy is proposed to reduce the energy offset at both hetero-interfaces within PSCs to decrease the V losses. For the interface of perovskite and electron transport layer where exists a mass of defects, it uses the pyromellitic acid to serve as a molecular bridge, which reduces non-radiative recombination and energy level offset.

Expanding the Conjugate Structure of Polymeric Carbon Nitride for Enhanced Light Absorption and Photothermal Conversion.

Macromol Rapid Commun

The development of efficient and inexpensive materials for light energy conversion is very important for achieving sustainable energy supply and carbon neutrality. Polymeric carbon nitride has become a promising material for light energy conversion due to its advantages of simple preparation and high physical and chemical stability. However, the pristine polymeric carbon nitride only absorbs light with a wavelength of less than 450 nm, and the energy conversion for low-energy photons is very limited.
