“…Fourth, these compounds can have different commutation processes, including cis-trans photoisomerization, intramolecular proton/charge transfer or photochromic reactions. [17][18][19] In this work, we explored the implications of the phenyl-acetylene π-bridge on the linear and non-linear optical properties of a fluorene-derived octupolar compound, namely OS. Of our particular interest is to analyze the dipolar contribution on the octupolar response.…”

Design parameters derived from structure-property relationships play a very important role in the development of efficient molecular-based functional materials with optical properties. Here, we report on the linear and nonlinear optical properties of a fluorene-derived dipolar system (DS) and its octupolar analogue (OS), in which donor and acceptor groups are connected by a phenylacetylene linkage, as a strategy to increase the number of delocalized electrons in the π-conjugated system. The optical nonlinear response was analyzed in detail by experimental and theoretical methods, showing that, in the octupolar system OS, the dipolar effects induced a strong two-photon absorption process whose magnitude is as large as 2210 GM at infrared wavelengths. Solvatochromism studies were implemented to obtain further insight on the charge transfer process. We found that the triple bond plays a fundamental role in the linear and nonlinear optical responses. The strong solvatochromism behavior in DS and OS was analyzed by using four empirical solvent scales, namely Lippert-Mataga, Kamlet-Taft, Catalán, and the recently proposed scale of Laurence et al., finding consistent results of strong solvent polarizability and viscosity dependence. Finally, the role of the acceptor groups was further studied by synthesizing the analogous compound 2DS, having no acceptor group.

“…Nano-composites, organic dyes and functional coordination compounds exhibit promising non-linear optical properties [107][108][109][110][111][112]. Mo(W)-Cu(Ag)-S clusters or cluster-based coordination polymers have proven useful in the last two decades due to their extensive d-p delocalized system and d-d conjugated system [81,113,114].…”

“…In recent years redox active centres containing transition metals have been tethered to dithienyl ethenes. These complexes have been reported for their ability to control electron transfer, switching luminescence or metal-metal communication [75]. As this area has grown extensively in recent years only a representative number of recent publications will be discussed here.…”

In this contribution a range of photo induced ligand rearrangements observed for first and second row transition metal and organometallic compounds are discussed. The processes discussed include photoinduced ligand exchange, linkage isomerisation and changes occurring within the coordination sphere of the compounds such as cis-trans and fac-mer isomerisations. The relevance of these processes for photocatalytic cycles or their application as synthetic tools is discussed where appropriate.
