Fluorescence Quenching in Hybrid Solar Cells Based on Electrodeposited ZnO

A study about fluorescence phenomena in hybrid donor-acceptor interfaces based on electrodeposited zinc oxide (e-ZnO) having different architectures is performed. In particular ITO/ZnO/P3HT and ITO/ZnO/P3HT:PCBM are investigated and their photoluminescence responses are compared with those of ITO/P3HT and ITO/P3HT:PCBM. As expected, ITO/ZnO/P3HT:PCBM and ITO/P3HT:PCBM present higher exciton quenching than ITO/ZnO/P3HT and ITO/P3HT respectively. Furthermore, the hybrid configuration ITO/ZnO/P3HT:PCBM displays a higher quenching percentage in a wider wavelength range than ITO/P3HT:PCBM, indicating a better photo-induced charge separation in e-ZnO based hybrid devices.

Organotin(IV)derivatives neurotoxicity and their modulation by Baclofen

Several new diorganotin(IV) and triorganotin(IV) complexes with 4-amino-3- (4-chloro phenyl)]-butanoic acid ( = Baclofen) have been synthesized and their structure investigated both in the solid state and in solution phase through spectroscopic methods (FT-IR, Mössbauer, 1H and 13C NMR). According to experimental analytical data, the stoichiometry of the complexes has been proposed as R2SnBac2 and R3SnBac, respectively for diorganotin(IV) and triorganotin(IV) baclofen complexes. (Baclofen = HBac; R = Me, Bu, Ph).

Synthesis, Characterization and in vitro antimicrobial activity of dialkyltin(IV)bis(fusidate) complexes.

The complexation of one steroid antibiotic of the fusidane family, sodium fusidate [sodium 2-16-acetyloxy-3,11-dihydroxy-4,8,10,14-tetramethyl-2,3,4,5,6,7,9,11,12, 13,15,16-dodeca hydro-1H-cyclopenta[a]phenanthren-7-ylidene)-6-methyl-hept-5-enoate = (Nafus)], by dialkyltin(IV) has been studied by conventional technique as FT-IR, Mössbauer and NMR spectroscopies. Analytical data supported the general formula Alk2Sn(IV)fus2 (Alk = Me, Bu). Infrared spectral data of the complexes imply the presence of both uni- and bidentate, ester-type and bridging carboxylate group, respectively. On the basis of FT-IR and 119Sn Mössbauer spectroscopy, in both Me2Sn(IV)fus2 and Bu2Sn(IV)fus2, trigonal bipyram…
