l-Homoproline-Directed Synthesis of Organic-Inorganic Metal Iodides for Second Harmonic Generation.

Three organic-inorganic metal iodides, namely, (NH)(l-hp)ZnI (), [Cd(l-hp)]CdI (), and (l-Hhp)(l-hp)PbI (), have been synthesized using l-homoproline (l-hp) as the structure-directing agent. These compounds feature different noncentrosymmetric structures and optical properties. In particular, compound shows a large second-harmonic-generation response of 3.

Multiple Functions of l-Thioproline in the Synthesis of Chiral Metal Bromides Showing Second-Harmonic-Generation Responses.

Three new homochiral metal bromides, namely, (l-Htp)CuBr (), (l-Htp)(l-tp)CdBr (), and (l-tp)ZnBr (), were prepared using l-thioproline as the chiral template. These compounds feature dimeric, chainlike, and monomeric structures. Their second-harmonic-generation (SHG) efficiencies are 0.

Synthesis and structure-dependent optical properties of two new organic-inorganic hybrid antimony(III) chlorides.

Two organic-inorganic hybrid antimony(III) chlorides, namely (CHN)SbCl (1) and (CHN)SbCl (2), were prepared using a facile solvent evaporation method. They have low-dimensional structures constructed from SbCl octahedra and triply protonated ,,','',''-pentamethyldiethylenetriamine cations. The organic cations exhibit different conformations in the two compounds.

Second-Harmonic Generation in Homochiral Antimony Halides Directed by l-Histidine.

Three homochiral organic-inorganic hybrid antimony halides, namely, (L-Hhis)SbCl (), L-Hhis·SbBr·HO (), and (L-Hhis)·SbI·4HO (), were prepared to investigate the structure-directing roles of l-histidine (l-his). These compounds feature dimeric, chainlike, and trimeric structures with different optical bandgaps. They display second-harmonic-generation (SHG) responses of 0.
