Resumo: | This work is composed of two parts. The first one describes the synthesis of organometallic compounds derived from Br2InCH2Br and dichalcogenoether ligands, RE(CH2)nER (E = Se, Te; n = 1, 3; R = Ph, p-C6H4NMe2), compounds 1 to 6, that are considered chemical intermediates with potential application in organic synthesis; and the second part describes the preparation of a series of InIII-E-MI ternary clusters (E = S, Se; MI = Cu, Ag; compounds 7 11), which show potential applications as semiconductors or photocatalysts. In the first part, bimetallic compounds Br3InCH2E(R)(CH2)nE(R)CH2InBr3 were obtained where n = 3, E = Se, Te e R = Ph, p-C6H4NMe2 (compounds 1, 3 and 6). Where n = 1, the compounds obtained have only one InIII atom, Br3InCH2E(Ph)CH2EPh (compounds 2 and 4); and also the bimetallic compound Br3InCH2Te(Ph)CH2Te(Ph)CH2InBr3 (5) could be obtained. Compounds 1 6 were characterized by Nuclear Magnetic Resonance of the corresponding chalcogen, and by Mass Spectrometry. In the second part, the InIII-E-MI ternary clusters (E = S, Se, MI = Cu, Ag) were synthesized from indium(III) chalcogenolates: In(EPh)3 (compounds 7 10) or BrIn(p-SeC6H4NMe2)2 (compound 11). Compounds 7 to 11 were characterized by X-ray Diffraction, Infrared Spectroscopy, and had their optical band gaps evaluated, in the solid state, by Ultraviolet/Visible Spectroscopy. Finally, compound 9 was used as sensitizing agent of TiO2, and used as photocatalyst to obtain hydrogen by visible light induced water splitting. The sensitizing process of TiO2 with compound 9 improved considerably the H2 evolution when compared with the use of pure TiO2 in the studied conditions. |

Na primeira parte, compostos bimetálicos do tipo Br3InCH2E(R)(CH2)nE(R)CH2InBr3 são obtidos quando n = 3, E = Se, Te e R = Ph, p-C6H4NMe2 (compostos 1, 3 e 6). Já quando n = 1, são obtidos compostos com apenas um átomo de InIII, Br3InCH2E(Ph)CH2EPh (compostos 2 e 4); e também o composto bimetálico Br3InCH2Te(Ph)CH2Te(Ph)CH2InBr3 (5). Os compostos 1 6 foram caracterizados por Ressonância Magnética Nuclear do calcogênio correspondente e por Espectrometria de Massas. Na segunda parte, os clusters ternários InIII-E-MI (E = S, Se, MI = Cu, Ag) são obtidos a partir de calcogenolatos de índio(III): In(EPh)3 (compostos 7 10) ou BrIn(p-SeC6H4NMe2)2 (composto 11). Os compostos 7 a 11 foram caracterizados por difração de raios X em monocristal, Espectroscopia Vibracional na região do Infravermelho e tiveram seus band gaps óticos avaliados, no estado sólido, através de Espectroscopia Ultravioleta/Visível. Por fim, o composto 9 foi utilizado como agente sensibilizador do TiO2 e testado como fotocatalisador da fotólise da água utilizando a luz visível para geração de hidrogênio. A sensibilização do TiO2 com o composto 9 aumentou consideravelmente a produção de H2 quando comparada a utilização do TiO2 puro nas condições estudadas.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em QuímicaUFSMBRQuímicaCalcogenolatos de índio(III)Clusters ternários InIII-E-MIOrganometálicos Br2InCH2BrLigantes dicalcogenoéteresIndium(III) chacogenolatesInIII-E-MI ternary clustersBr2InCH2Br organometallic compoundsDichalcogenoether ligandsCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICASíntese e caracterização de novos compostos envolvendo Índio e CalcogêniosSynthesis and characterization of new compounds involving Indium and Chalcogensinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisLang, Ernesto Schulzhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4786424E6Bortoluzzi, Adailton Joãohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4727981D7Lima, Geraldo Magela dehttp://lattes.cnpq.br/8226529794937801Hörner, Manfredohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783542Z5Giacomelli, Vanessa Schmidthttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4733375T6http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4139056T1Mello, Melina de Azevedo1006000000004003003003003003003000c9d7568-d5c4-466d-b807-0125a7d37b972bc8f27a-83ce-4766-b038-7ed113952de854de7942-f611-4d6f-81b7-f54b7940d6e5e3fc6659-9d3a-4eee-9b61-c3372216ba8c4107ba2b-cbf3-4291-b39f-aafa00198928070561da-7f47-4e71-8a41-6e3759afbf35info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMELLO, MELINA DE AZEVEDO.pdfapplication/pdf9156959http://repositorio.ufsm.br/bitstream/1/4273/1/MELLO%2c%20MELINA%20DE%20AZEVEDO.pdf0cced4ff3252390b34b1a6401599f837MD51TEXTMELLO, MELINA DE AZEVEDO.pdf.txtMELLO, MELINA DE AZEVEDO.pdf.txtExtracted texttext/plain166899http://repositorio.ufsm.br/bitstream/1/4273/2/MELLO%2c%20MELINA%20DE%20AZEVEDO.pdf.txt1cf4e6f43a8a3467b47dd1744716026aMD52THUMBNAILMELLO, MELINA DE AZEVEDO.pdf.jpgMELLO, MELINA DE AZEVEDO.pdf.jpgIM Thumbnailimage/jpeg4686http://repositorio.ufsm.br/bitstream/1/4273/3/MELLO%2c%20MELINA%20DE%20AZEVEDO.pdf.jpgbb46d3e82fd997bcd52e114e0d3f92d5MD531/42732017-07-25 11:05:11.697oai:repositorio.ufsm.br:1/4273Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132017-07-25T14:05:11Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
