Organic transformations are very important in synthetic organic chemistry and are used immensely in pharmaceuticals. Polyaniline is a marvelous and exceptional conducting polymer because of its extensive and valuable applications. Various modified polyaniline derivatives were developed by researchers and explored as solid heterogeneous catalysts for synthesizing important organic compounds through different organic transformations. Polyaniline-supported catalysts have many advantages: easy synthesis, environmental stability, environmental friendliness, high yield, short reaction times, the requirement for green solvent or solventless medium, and excellent reusability. In past years, polyaniline-supported catalysts have been widely used in various important organic syntheses under solvent-free or green reaction conditions. Hence, here is a comprehensive, detailed review of the application of polyaniline catalysts in organic transformations with all of their advantages and future scope.

Interactions between manganese dioxides (MnO) and dissolved organic matter (DOM) have long been the subject of scientific inquiry. However, the effect of MnO crystallinity on the DOM fate remains unclear. Herein, we comprehensively investigate the adsorption, protection, and mineralization of DOM by MnO with various crystallinities (order of crystallinity: γ-30 < γ-90 < γ-120).

Controlling symmetrical or asymmetrical growth has allowed a series of novel nanomaterials with prominent physicochemical properties to be produced. However, precise and continuous size growth based on a preserved template has long been a challenging pursuit, yet little has been achieved in terms of manipulation at the atomic level. Here, a correlated silver cluster series has been established, enabling atomically precise manipulation of symmetrical and asymmetrical surface structure expansions of metal nanoclusters.

The packing of organic molecular crystals is often dominated by weak non-covalent interactions, making their rearrangement under external stimuli challenging to understand. We investigate a pressure-induced single-crystal-to-single-crystal (SCSC) transformation between two polymorphs of 2,4,5-triiodo-1-imidazole using machine learning potentials. This process involves the rearrangement of halogen and hydrogen bonds combined with proton transfer within a complex solid-state system.

During use of sodium hypochlorite bleach, gas-phase hypochlorous acid (HOCl) and chlorine (Cl) are released, which can react with organic compounds present in indoor air. Reactivity between HOCl/Cl and limonene, a common constituent of indoor air, has been observed. The purpose of this study was to characterize the chemical species generated from gas-phase reactions between HOCl/Cl and limonene.

Polymer electrolytes incorporated with fillers possess immense potential for constructing the fast and selective Li conduction. However, the inhomogeneous distribution of the fillers usually deteriorates the microdomain consistency of the electrolytes, resulting in uneven Li flux, and unstable electrode-electrolyte interfaces. Herein, we formulate a solution-process chemistry to in situ construct gel polymer electrolytes (GPEs) with well-dispersed metal-organic frameworks (MOFs), leading to a uniform microdomain structure.
