“…For instance the platinum(II) square-planar complex trans-[P(n-Bu) 3 ] 2 Pt[(C C-p-C 6 H 4 -C C-p-C 6 H 5 ] 2 [326,346,347] was reported for efficient nonlinear absorption in solution, [326,[346][347][348] and series of derivatives were prepared with improved properties. [294,[349][350][351][352][353][354][355][356][357][358] The use of PMMA monoliths hosting platinum derivatives was an efficient route towards OPL materials. [278,359] The measured linear transmissions were nearly 90% in the visible and NLO properties were maintained in the solid.…”

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”.

“…10. The 77 K solid state and EtOHÀ ÀMeOH glass of these complexes show intense green-to-yellow luminescence with microsecond lifetimes upon photoexcitation (231). Branched, Pt(II)-alkynyl complexes with polyaromatic ligands also show analogous properties, but with red-shifted emission in the range of 600-800 nm.…”

“…This finding is supportive of a triplet IL emission derived mainly from the central triethynylhexabutyltruxene moiety. However, the emission energies observed for the branched complexes were found to show a red shift on going from palladium complexes to platinum analogues, which suggested the involvement of some triplet MLCT character in the emissive state [76,77,79]. Therefore, the emission of these complexes was assigned as derived from a mixed 3 IL [p/p * (C^C) 3 truxene]/ 3 MLCT [dp(Pt)/p * (C^C) 3 truxene] state with predominantly IL character.…”

“…This was synthesized according to modification of a literature procedure for the related platinum(II) phosphine alkynyl complexes [70,77]. [{Cl(PEt 3 ) 2 PtC^C} 3 truxene] (0.12 g, 0.10 mmol) and 1-ethynyl-4-methoxybenzene (0.05 g, 0.40 mmol) were dissolved in a mixture of THF (20 mL) and triethylamine (10 mL).…”
