Design of non-linear optical materials based on inorganic compounds

Abstract: This Thesis is concerned with the prediction, synthesis, characterization and testing ofinorganic materials for Second Harmonic Generation (SHG).Chapter One describes the fundamentals of non-linear optics, and poses theproblems, and some of their solutions which confront the synthetic chemist and the theoreticalprediction of the second order hyperpolarizability constant β using CNDOVSB calculations.Chapter Two describes the design, implementation and calibration of an apparatusfor measurements of the second harmonic generating efficiency of solids based on the Kurtzpowder technique, and a solvatochromic method for the determination of β.Novel compounds with potential chirality due to atropisomerism, asymmetricoctahedral structures, and asymmetric tetrahedral symmetry of metal centers are discussed inChapters Three to Five.Chapter Three surveys the use of pentane-2,4-dionato- ligands and theircoordination compounds as possible NLO active materials. The single crystal X-raystructures of bis(triphenylphosphine)(4-nitrobenzoylacetonato)palladium(II) tetrafluoroborateand tris(triphenylphosphine)[3-(2,4-dinitrophenyl)-pentane-2,4-dionato]palladium(II)tetrafluoroborate were determined.Chapter Four describes the syntheses, characterization and SHG properties oftrans-β-ionylidenecyanoacetic acid (2-cyano-3-methyl-5-(2,6,6-trimethyl-l-cyclohexen-1-yl)-2,4-pentadienoic acid) and some of its metal and non-metal salts.Chapter Five describes the synthesis, characterization and second harmonicgeneration properties of some platinum(II) and palladium(II) complexes of β-ionylidenecyanoacetic acid.Chapter Six describes the use of conventional asymmetric carbon centers tointroduce chirality into centrosymmetric compounds. The chiral compound (L)-N-[2-cyano-3-methyl-5-(2,6,6-trimethyl-1 -cyclohexene-1 -yl)-2,4-pentadiene-1 -one]-L-proline and someof its salts were synthesized from β-ionylidenecyanoaeetic acid and tested for SHG.
