The assemblies were prepared by using a layer-by-layer, Atomic Layer Deposition (ALD), self-assembly approach. In the procedure, addition of an electron acceptor viologen derivative followed by a RuII(bpy) chromophore and a pyridyl derivative of the water oxidation catalyst [Ru(bda) (L)2] (bda = 2,2\u2032-bipyridine-6,6\u2032-dicarboxylate)2, were linked by ALD by addition of the bridge precursors TiO2, ZrO2, and Al2O3 as the bridging groups giving the assemblies, FTO|nanoITO|\u2013MV2+\u2013ALD MO2\u2013RuP22+\u2013ALD M\u2032O2\u2013WOC. In a series of devices, the most efficient gave water oxidation with an incident photon to current efficiency of 2.2% at 440 nm. Transient nanosecond absorption measurements on the assemblies demonstrated that the slow step in the intra-assembly electron transfer is the electron transfer from the chromophore through the viologen bridge to the nanoITO electrode.<\/jats:p>","DOI":"10.1063\/5.0007383","type":"journal-article","created":{"date-parts":[[2020,6,24]],"date-time":"2020-06-24T07:58:47Z","timestamp":1592985527000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["Chemical approaches to artificial photosynthesis: A molecular, dye-sensitized photoanode for O2 production prepared by layer-by-layer self-assembly"],"prefix":"10.1063","volume":"152","author":[{"given":"Degao","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of North Carolina at Chapel Hill 1 , Chapel Hill, North Carolina 27599-3290,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byron H.","family":"Farnum","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Auburn University 2 , Auburn, Alabama 36849,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher J.","family":"Dares","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Florida International University 3 , 11200 SW 8th St., Miami, Florida 33199,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7006-2608","authenticated-orcid":false,"given":"Thomas J.","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of North Carolina at Chapel Hill 1 , Chapel Hill, North Carolina 27599-3290,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2020,6,24]]},"reference":[{"key":"2025101316420115900_c1","doi-asserted-by":"publisher","first-page":"37","DOI":"10.1038\/238037a0","volume":"238","year":"1972","journal-title":"Nature"},{"key":"2025101316420115900_c2","doi-asserted-by":"publisher","first-page":"6446","DOI":"10.1021\/cr1002326","volume":"110","year":"2010","journal-title":"Chem.
