A new route for fabrication of photoactive materials in organic-inorganic hybrid solar cells is presented in this report. Photoactive materials by blending a semiconductive conjugated polymer with an organolead halide perovskite were fabricated for the first time. The composite active layer was then used to make planar heterojunction solar cells with the PCBM film as the electron-acceptor. Phot...

Tm3+/Yb3+-codoped heavy metal oxide-halide glasses have been synthesized by conventional melting and quenching method. Structural properties were obtained based on the Raman spectra, indicating that halide ion has an important influence on the phonon density and maximum phonon energy of host glasses. Intense blue and weak red emissions centered at 477 and 650 nm, corresponding to the transition...

A simple physical model and theory have been proposed to investigate the electrocompression behavior of electrodeposited halide (chloride, bromide, and iodide) monolayer at the Au(111) electrode surface. By establishing the statistical thermodynamic formulas, the effective pair interaction energy, 2D spreading pressure, 2D isothermal compressibility, and electrode potential-coverage (θ-E) curve...

Transition metal-catalyzed C–C cross-coupling reactions are among the most powerful transformations known to organic chemists, and have received considerable attention over the last decades. For this reason, the development of mild chemo-, regio-, and stereoselective syntheses for the formation of carbon–carbon bonds catalyzed by metal complexes is of great interest. These methods have had a pr...

A series of unprecedented organoiron complexes of the formal oxidation states -2, 0, +1, +2, and +3 is presented, which are largely devoid of stabilizing ligands and, in part, also electronically unsaturated (14-, 16-, 17- and 18-electron counts). Specifically, it is shown that nucleophiles unable to undergo beta-hydride elimination, such as MeLi, PhLi, or PhMgBr, rapidly reduce Fe(3+) to Fe(2+...

Among various all-inorganic halide perovskites exhibiting better stability than organic-inorganic halide perovskites, α-CsPbI3 with the most suitable band gap for tandem solar cell application faces an issue of phase instability under ambient conditions. We discovered that a small amount of two-dimensional (2D) EDAPbI4 perovskite containing the ethylenediamine (EDA) cation stabilizes the α-CsPb...

The spectroscopic methods UV-Vis absorption, FT-IR and (13)C and (19)F NMR demonstrate that 1,2-diiodoperfluoroethane (DIPFE) and 1,6-diiodoperfluorohexane (DIPFH) display strong halogen bonding with halide anions. A 1 : 1 stoichiometry of DIPFE or DIPFH with halide anion is confirmed, and the bonding constants and molar extinction coefficients are obtained. With the same halide, DIPFH possesse...

The main advantage of metal-organic frameworks (MOFs) catalysts over other heterogeneous is that they can be designed to have reaction sites within molecularly well-defined and tunable structures achieve high catalytic performance. In recent years, several types with copper(II) been synthesized for a wide range applications but there still few reports MOFs containing copper(I). Herein, the rod-...
