The photophysical properties of monomeric and dimeric ruthenium polypyridyl complexes immobilized in sol-gel matrices

Spectroscopic characterization of zirconium(IV) and hafniumf(IV) gallate phthalocyanines in monolithic silica gels obtained by sol–gel method

“…Sol-gels (either monoliths or thin films) are very useful to encapsulate a range of guests such as inorganic clusters [10][11][12], lanthanide complexes [13,14], or laser 0925 dyes [15][16][17]. Different complexes, including metalloporphyrin and metallophthalocyanine based systems, have also been encapsulated by sol-gel processing to give organic-inorganic hybrids, potentially useful in catalysis [18][19][20][21][22]. The application of metalloporphyrins and metallophthalocyanine doped sol-gel materials as catalysts for the oxidation of alkenes, aromatic, halogenoorganic and other organic or inorganic compounds oxidation have been reported [23,24].…”

Photoinduced Energy Transfer between Ruthenium and Osmium tris-Bipyridine Complexes Covalently Pillared into γ-ZrP

“…These materials have potential for use in applications that require key functions such as light-harvesting antenna, , long-lived photoinduced charge separation − for use in solar energy conversion and storage, and electro-optical molecular devices. Various media such as silica, sol−gel glasses, transition metal chalcogenophosphates, membranes, Langmuir−Blodgett films, − and microporous crystalline matrixes such as zeolites, , phosphates, ,,,− and phosphonates , have been used to organize photochemically active compounds.…”

The Effective Electron‐Transfer Distance in Dinuclear Ruthenium Complexes Containing the Unsymmetrical Bridging Ligand 3,5‐Bis(2‐pyridyl)‐1,2,4‐triazolate

“…Because the unsymmetrical component in bpt -may be exploited to facilitate vectorial electron-and energy-transfer processes in polynuclear complexes, which form the basis of novel molecular-scale devices, [9,11,12,24,25,[27][28][29][30][31][32][33][34][35][36][37][38][39][40] stereochemical effects may also offer a novel means of "fine-tuning" the metal-metal interactions.…”
