“…Binding enthalpy calculations suggest that species bound with hydroxamate or carboxylate anchors would exhibit similar interfacial electron transfer but that the hydroxamate anchor would be 33% more stable than a carboxylate anchor on anatase TiO 2 [21]. Experimental data comparing analogous organic azo dyes with hydroxamate or carboxylate anchors support these predictions [22]. While no direct studies have compared hydroxamates to phosphonates on TiO 2 , there is evidence that hydroxamates may be more suitable anchors than carboxylates for water-oxidation photoanodes, especially given that hydroxamic acids are oxidation resistant, stable under neutral and basic aqueous conditions, and synthetically accessible directly from carboxylic acid functional groups, as shown in Figure 4 [24].…”

“…In summary, these data suggest a slightly better light-harvesting ability for the dye bearing the hydroxamate anchor, as compared to the dyes bearing carboxylate and phosphate anchors, which is in agreement with the corresponding experimental observations. 23 We believe that the impressive photo-absorption properties for dyes bearing the hydroxamate anchor can be achieved as long as the elaborate molecular modifications,…”
