“…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.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

Stilbenes and their derivatives, stilbenoids, form a multidisciplinary field that combines many important branches of chemistry, biology, and physics. The number of publications on stilbenes available on the Internet has reached approximately 32,000. Classical and modern synthetic organic chemistry (more than 6300 articles) provide a whole arsenal of stilbenes of different structures. The unique features of this class of compounds, including a combinatihon of fluorescence, phosphorescence, photochrome, photochemical, and photophysical properties, are paving the way for numerous fundamental research and practical applications. Specifically, ( 1 ) stilbenes are used as dyes, brighteners, whiteners of paper and textile, and photobleachers; ( 2 ) stilbenes and its combination with polymers and inorganic materials have been made as a basis for numerous optical and measuring instruments, devices, and apparatuses for dye lasers, organic solid lasers, and scintillators, phosphorus, neutron, and radiation detectors, electrophotographic photoconductor and image‐forming apparatus, and photochromic, light‐transmitting, dichroic, electroluminescent nonlinear optic, and organic–inorganic hybrid multichromophoric optical limiting materials; ( 3 ) stilbenoids are naturally present in plants and have been used as drugs and antitumor agents; and ( 4 ) stilbene derivatives have been used as molecular probes and labels for investigation of structure and dynamic properties of proteins and biomembranes. This article concisely covers the main aspects of stilbenes synthesis, chemical activity, and application.

“…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.…”
