Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...

Synthesis of guanidine from ammonium thiocyanate in solid state

Journal of the Brazilian Chemical Society, 2004
Guanidine is an important substance for modern living beings as well as for the prebiotic chemistry. We studied the reaction between ammonium and thiocyanate species in solid state with different substances (river sand, kaolin, transition metals, salts ...

Synthesis some of heterocyclic compounds derived from thymol [PDF]

مجلة التربية والعلم, 2018
A series of some hydrazones derivatives (3-7) have been synthesized from the reaction of hydrazide (2) with substituted benzaldehyde. While oxazridine derivatives (8-12) were synthesized by oxidation with hydrazones derivatives (3-7) with m-chloro per ...

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.

Heterocyclic systems containing S/N regioselective nucleophilic competition: Facile synthesis, antitubercular and antimicrobial activity of thiohydantoins and iminothiazolidinones containing the benzo [PDF]

Journal of the Serbian Chemical Society, 2005
The required compounds N-aryl-N'-(3-chloro-2-benzo[b]thenoyl)-thioureas 1a-k were prepared by condensing 3-chloro-2-benzo[b]thenoyl chloride with different arylamines using ammonium thiocyanate, which in turn when treated with chloroacetic acid, yielded ...
