Synthesis, characterization, third-order non-linear optical properties and DFT studies of novel SUBO bridged ball-type metallophthalocyanines

Abstract

Novel 4,4'-(((2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diyl)bis(2-methylpropane-2,1-diyl))bis(oxy)) (SUBO) bridged ball-type metallophthalocyanines were synthesized starting from 4,4'-(((2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diyl)bis(2-methylpropane-2,1-diyl))bis(oxy))diphthalonitrile with convenient metal salts in 2-N, N-dimethylaminoethanol. The new bisphthalonitrile compound was obtained from 2,2'-(2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diyl)bis(2-methylpropan-1-ol) and 4-nitrophthalonitrile in acetonitrile...

Crystal Structure, Topological and Hirshfeld Surface Analysis of a Zn(II) Zwitterionic Schiff Base Complex Exhibiting Nonlinear Optical (NLO) Properties Using Z-Scan Technique

“…One of the NLO behavior is the third harmonic generation (THG), where light of angular frequency (ω) is converted into light at three times higher angular frequency (3ω) upon absorption by the nonlinear optical material [18]. In the recent past, investigations on the NLO properties of materials for optical limiting (OL) behavior have been motivated by the need to guard sensitive photonic devices and human eyes from exposure to high intensity laser light [19,20]. By tuning the factors affecting the nonlinear behavior, specifically the ease of processability, the uniqueness of metal ions, and changing the symmetry of the molecule, it is possible to modulate the nonlinear response along with optical limiting performance of a material [21,22].…”
