Synthesis, growth, and characterisation of a novel organic–inorganic perovskite-type hybrid system based on glycine

Abstract

A new organic-inorganic hybrid with the empirical formula [NH3-CH2-COOH]CdCl3.H2O has been crystallised, and the structure was solved at room temperature (system (orthorhombic), space group (Pcam), unit parameters cell (a = 7.433( 10) Å, b = 7.743(2) Å, c = 25.346(6) Å), volume 1458.76 (5) Å 3 ), Z = 8). The asymmetric unit cell consists of a combination of [Cd 0.5 Cl3]anions, one organic + NH3(CH2)CO2H cations, and one water molecule to form a twodimensional perovskite system. The hydrogen-bonding network ensures cohesion between these layers. The micro-Raman spectroscopy measurement technique is used to probe organic−inorganic halide perovskite vibration modes. The compound was, also, characterised using the vibrating sample magnetometer VSM and the UV-visible absorption techniques.

Biomolecules incorporated in halide perovskite nanocrystals: synthesis, optical properties, and applications

“…In this regard, a huge number of new HP compositions have been formed using biomolecules including but not limited to alanine, 64,121,122 3-aminobutyric acid, 123 4-aminobutyric acid (GABA), 124,125 5-aminovaleric acid and its derivatives, 122,[126][127][128] cysteine, 129 glycine, 130 histidine, 129 leucine, 122 lysine, 65,131 ornithine, 131 phenylethylamine, 126,[132][133][134][135][136][137] proline, 138 and taurine. 129 While a few of the examples listed above represent novel ABX 3 HPNCs, the vast majority represent novel 2D perovskite layered structures.…”

Characterization of M-curcumin complexes (M= Cu, Co, Ag) in turmeric rhizome as sensitizer candidates in dye-sensitized solar cell (DSSC)

“…Efforts to increase the absorbance of light can be made by sensitizing semiconductors with transition metal complexes. Transition metal complexes that are capable of acting as photosensitizers are complexes with metals that are in a low oxidation state, have low electronegativities, and have excess electron densities such as Cu(II), Co(II), Pt(II), Fe(II), and Mn (II) caused by the additional electron density of the s-bond ligand [11]. In curcumin compounds, there are ketone groups and hydroxyl groups.…”
