First-principles theory investigation on structural and photoelectronic properties of formamidinium lead halide perovskites.
Formamidinium lead halide perovskites have attracted wide attention as photoelectronic conversion materials due to the high photoelectronic conversion efficiency (PCE), low cost and simple synthetic process. The structural, electronic and optical properties of mixed formamidinium lead halide perovskites FAPbIxCl3-x (FA=NH2CH=NH2?, x=0~3) have been investigated by the first-principles theory. Our...

Structure Tuning of Metal Phosphonates: Syntheses, Structures and Characterizations of Two New Lead (II) Trisphosphonates
Two lead (II) trisphosphonates, [Pb3(H3L1)2(H2O)] (1) and [Pb5(HL2)(H3L2)(H4L2)(H2O)2][(H2O)2] (2), have been synthesized from two trisphosphonate ligands and characterized by EA, IR, UV–vis, TGA, powder and single-crystal X-ray diffraction methods. The single-crystal X-ray diffraction analyses reveal that they both feature three-dimensional framework structures. The lead (II) ions are mainly fiv...

Macrocyclic Amine-Linked Oligocarbazole Hollow Microspheres: Facile Synthesis and Efficient Lead Sorbents
Novel macrocyclic amine-linked oligocarbazole hollow microspheres are synthesized via a one-step oxidative method in aqueous solution. Upon altering the oxidants and acidic media, the average diameters of the obtained hollow microspheres are tunable from 0.23 to 2.0 μm. With attractive amine and carbazole functionalities, exposed surface area, thermostability, and photoluminescent properties, the...

Superb Adsorption Capacity and Mechanism of Poly(1-amino-5-chloroanthraquinone) Nanofibrils for Lead and Trivalent Chromium Ions
Poly(1-amino-5-chloroanthraquinone) (PACA) nanofibrils were applied as new nano-adsorbents for heavy metal removal from aqueous solutions. Adsorption properties including adsorption capacity, selectivity, kinetics, mechanism, and isotherm of PACA nanofibrils were studied in detail. The competitive adsorption of the nanofibrils for Pb(II) and Cr(III) in binary mixture systems was investigated. The ...

Polyvinyl-butyral/lead zirconate titanates composites with high dielectric constant and low dielectric loss
A novel polymeric composite with high dielectric constant and low dielectric loss has been developed by mixing polyvinyl-butyral (PVB) with ferroelectric ceramic lead zirconate titanates (PZT). The dependence of the dielectric constant on frequency and polymer volume fraction was investigated. The composite shows a high dielectric constant which gives better frequency stability, and lower...

[ACS Appl. Mater. Interfaces] Ligand-Induced Tunable Dual-Color Emission Based on Lead Halide Perovskites for White Light-Emitting Diodes
Cesium lead halide perovskites (CsPbX3, X = Cl, Br, and I) have emerged as an important class of colortunable light-emitting materials in the past 4 years. However, single-CsPbX3 nanostructures with dual-color emission remain scarce. Here, we demonstrate dual-color emission from lead halide perovskite nanowires induced by the surface ligands, that is, oligomeric methoxypolyethylene glycol (MEOPE...
