“…For instance the thermal behavior and possibility to enhance the second harmonic generation and improve the stability of the optical properties by using covalent grafting to the matrix were investigated. [277,[280][281][282][283][284][285][286][287][288][289][290][291] Several types of chromophores bearing silane groups were proposed (Figure 24). Thermal stability of the nonlinear optical properties were improved by combining covalent bonding of the dyes and hydrogen bonding or by playing with the sterical hindrance.…”

“…Thermal stability of the nonlinear optical properties were improved by combining covalent bonding of the dyes and hydrogen bonding or by playing with the sterical hindrance. [282,283,287] Such interactions were for example obtained by incorporation of aniline-silane in the matrix. [287] Moreover it was shown that the topological localization of the silane groups along the structure and the type of spacer used impacts the NLO properties.…”

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”.

Dinuclear Ruthenium(II) Complexes That Induce and Stabilise G‐Quadruplex DNA

A series of dinuclear ruthenium(II) complexes were synthesised, and the complexes were determined to be new highly selective compounds for binding to telomeric G-quadruplex DNA. The interactions of these complexes with telomeric G-quadruplex DNA were studied by using circular dichroism (CD) spectroscopy, fluorescence resonance energy transfer (FRET) melting assays, isothermal titration calorimetry (ITC) and molecular modelling. The results showed that the complexes 1, 2 and 4 induced and stabilised the formation of antiparallel G-quadruplexes of telomeric DNA in the absence of salt or in the presence of 100 mM K(+)-containing buffer. Furthermore, complexes 1 and 2 strongly bind to and effectively stabilise the telomeric G-quadruplex structure and have significant selectivity for G-quadruplex over duplex DNA. In comparison, complex 3 had a much lesser effect on the G-quadruplex, suggesting that possession of a suitably sized plane for good π-π stacking with the G-quadruplets is essential for the interaction of the dinuclear ruthenium(II) complexes with the G-quadruplex. Moreover, telomerase inhibition by the four complexes and their cellular effects were studied, and complex 1 was determined to be the most promising inhibitor of both telomerase and HeLa cell proliferation.
