Physicochemical properties of Ru(bpy)32+ entrapped in silicate bulks and fiber thin films prepared by the sol–gel method

Electrochemiluminescence determination of codeine or morphine with an organically modified silicate film immobilizing Ru(bpy)32+

“…4), Ru(bpy) 3 2+ emission maximum wavelength underwent a 26 nm blue shift (607 to 581 nm) as the complex was immobilized within the solid matrix, indicating that suppression of the vibrational deactivation and restriction of the mobility of the Ru(bpy) 3 2+ in an excited state was due to the rigidity of the ORMOSIL matrix; moreover, some specific host-guest interaction might also partly explain this phenomenon (24). The absorption feature of Ru(bpy) 3 2+ entrapped within the ORMOSIL film remained the same as Ru(bpy) 3 2+ dissolved in water solution, which further confirms that there was no interaction between Ru(bpy) 3 2+ and the ORMOSIL matrix in the energetically ground state.…”

Luminescence of Lanthanides from Xerogels Embedded in Mesoporous Matrices

“…Development of multicolor luminescent images with the use of blue PL of PAA, light emission of quantum dots, lanthanides and also dye molecules [66,67] from xerogels in PAA needs further experimental work. In addition to photoluminescent images revealing strong light emission at direction along the channels of the pores it is also attractive to aim recently reported sol-gel synthesis of X-ray phosphors [68,69] for development light transformers on the basis of matrices with the spatial anisotropy of DOS like PAA.…”

Electrogenerated chemiluminescence of ruthenium (II) bipyridyl complex directly immobilized on glassy carbon electrodes

“…Immobilization provides mechanical stability and enables the subtle modifications of dopant properties specific to host-guest interactions [3]. Sol-gel materials [3,9] including xerogels [10] have been used to immobilized ruthenium complexes to produce gel support matrices with good stability, optical permeability and biocompatibility. Nanoparticles (NPs) and nanotubes (NTs), for example, AuNPs [11,12], SiNPs [13], and CNTs have been used as dopants to form composite systems to prepare modified electrodes for ECL determinations [11][12][13][14][15][16].The ECL systems have shown a wide linear range, high sensitivity and good stability in the detection of DNA, proteins and amines.…”
