While on both these surfaces the complex exhibits a single exponential &lt;120 fs injection, the back electron transfer reaction is slower on the oleic acid capped TiO2 surface early on while it is faster on the same surface at longer times than on poly(vinyl)alcohol capped TiO2. The probable origin of these disparate observations has been analyzed.</p>1 aBanerjee, Tanmay1 aDas, Amitava1 aGhosh, Hirendra, N.  uhttps://library.ncl.res.in/content/interfacial-charge-recombination-osii-polypyridyl-resorcinol-complex-oleic-acid-capped-0
