An excursion in the second-order nonlinear optical properties of platinum complexes

Progress and perspectives on strategies to control photochemical properties in Metallo-Dithiolene Donor-Acceptor systems

“…Among these, several classes of d 8 -metal complexes where the metal is coordinated to a variety of ligands spanning from nitrogen ligands, cyclometalated, alkynyl to sulfur ligands [13, -21]. Un updating on these systems addressed to highlight the special role of related platinum complexes as NLO-active chromophores and their potential for electrooptical devices and optical communications, can be found in a recent interesting review by V. Guerchais, D. Roberto et al [22].…”

Two state “ON–OFF” NLO switch based on coordination complexes of iron and cobalt containing isomeric ligand: a DFT study

“…Molecules with switchable second-order nonlinear optical properties have gained a great deal of interest because of their potential use in photonic devices. [10][11][12] The progress of innovative nonlinear optical materials is essential for sustainable development in nanoscience and nanotechnology. [13][14][15] The literature study revealed that various strategies including bond length alteration, metal-ligand frameworks, excess electron incorporation, extended conjugation in plinkage, and accommodation of donor-acceptor fragments connected via a p-network have been frequently adopted to improve the NLO properties of materials.…”

“…Sulfur and nitrogen-bonded thiocyanato linkage isomers of dicarbonyl-p-cyclopentadienyl iron and tricarbonyl-pcyclopentadienyl molybdenum have been investigated for their NLO response. [10][11][12]16,64 Therefore, we are interested to explore the NLO effects of ligand isomeric complexes of transition metals with different ambidentate ligands. Due to the nature of charge-transfer excitations, these ligand isomeric complexes are anticipated to exhibit NLO contrasts.…”
