“…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”.

“…When the Pt-polymers with triplet excitons were incorporated in OSCs based on a bulk heterojunction architecture with fullerene the PCE increased up to 0.3% (Köhler et al 1996). These Pt-polymers have blue absorption Lindgren et al 2007), while solar light peaks in the red. Thus for practical applications other Pt-and Pdcontaining polymers have been synthesized with conjugated spacers R which have strong electron-acceptor character and various such heterojunction devices have been fabricated using this concept (Köhler & Bässler 2009).…”

“…[14] Platinum(II) acetylides on the other hand, are only slightly colored and well known to possess strong excited state absorption, [21][22][23][24][25] giving rise to efficient nonlinear absorbing properties. [15] Previous results presented by a number of authors, [21,[25][26][27][28][29][30][31] demonstrate the fundamental photophysical properties of platinum (II) acetylides and discuss their potential use in optical power limiting (OPL) applications.…”

Platinum(II) acetylides were incorporated into poly(methyl methacrylate) (PMMA) glasses to obtain solid‐state nonlinear optical devices. We report on device fabrication, structural, chemical, and mechanical properties, as well as the optical limiting capabilities of the final solids. Two different guest‐host systems are presented: 1) Dye molecules functionalized to be readily dispersed in methyl methacrylate (MMA) and subsequent in situ polymerization of the MMA yielding solid PMMA host matrices. 2) Dye molecules functionalized to copolymerize with MMA forming covalent bonds between the guest and the PMMA host matrix. A range of doped organic solids were prepared, reaching concentrations up to 13 wt% of the guest molecule. Raman spectra of the doped solid devices indicate that the chemical structure of the nonlinear dyes remains intact upon the polymerization of the solid matrix. Luminescence spectra confirm that the basic photophysical properties observed for the same solute molecules in THF are maintained also in the solid state. Optical power limiting (OPL) characterization reveal clamping levels for the dyes nonbonded to the solid host being less than 4 µJ at pulse energies up to 110 µJ at 532 nm (f/5 arrangement and 5 ns pulses), which is comparable to the performance of similar dyes in THF solutions. In contrast, the highly crosslinked solid possesses a higher clamping level (8 µJ) at the same nominal concentration.
