Molecular Hybrid Optical Limiting Materials from Polyhedral Oligomer Silsequioxane: Preparation and Relationship between Molecular Structure and Properties

Abstract: A series of new molecular hybrids with stilbene chromophore (H1-H4) are prepared by hydrosilylation of octahydridosilsesquioxane (T 8 H ). All these stilbene-containing hybrid materials are soluble in common organic solvents, such as chloroform, toluene, THF, and 1,2-dichloroethane, and possess good film-forming properties. Their structures and properties are characterized and evaluated by FT-IR, NMR, UV, PL, TGA, DSC, nonlinear optical (NLO), and optical limiting (OL) analyses. The results show that the therm… Show more

“…X. Su and coworkers reported the synthesis of POSS modified with azobenzene, acetylene or stilbene derivatives exhibiting nonlinear absorption. [363][364][365] These systems exhibited large P (3) susceptibility and efficient reverse saturable absorption with enhanced thermal stability. They were processed as thin films.…”

“…With the development of laser technology, nonlinear optical materials have attracted considerable interest for protection of human eyes, sensors and sensitive optical components from laser damage [1][2][3]. Nonlinear optical materials with large third-order nonlinear susceptibility find application in photonic devices such as ultrafast optical switching, optical data storage, and optical limiting.…”
