Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.

A Flexible Poling‐Free Piezoelectric Energy Harvester Based on Gradient Ti‐Doped BiFeO3 Films

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A self‐aligned polarization is realized in compositional gradient Ti‐doped BiFeO3 films via the formation of defect dipoles and strain gradient. The self‐poling behavior is robust to resist high electric field and elevated temperature. The fabricated poling‐free piezoelectric energy harvester delivers output comparable to the poled ones.

Tracking the Reaction of Organoazides with Linear Chromium Silylamides

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The multifaceted outcome of the interaction of linear chromium silylamides with organoazides is presented. It leads to terminal and bridging imido complexes, as well as azide adducts. With acylazide, a terminal chromium oxide is obtained. The reaction of organoazides with a linear chromium(I) silylamide leads to the observation of rare monomeric and ...

Synthesis and Reactivity of Iodepinium Salts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient oxidative cyclization of (Z)‐iodostilbenes grants access to the long‐elusive class of seven‐membered diaryliodonium salts — the iodepinium triflates. X‐ray analysis reveals their distinctly nonplanar geometry, while reactivity studies uncover unprecedented pathways, including copper‐mediated conversion to phenanthrene and chalcogen‐induced

Dibenzosuberene‐Winged Polycyclic Aromatic Hydrocarbons

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The twisted acene 8, which features two dibenzosuberene “wings”, was prepared by the addition of a crowded aryne to a similarly “winged” cyclopentadienone. Compound 8 is chiral, and it has a high barrier to thermal racemization (ΔG‡rac = 36 kcal/mol), but it undergoes fast photochemical racemization even in ambient light.
