Acetone ch3coch3

All starting materials were commercially available reagent grade and were used without any further purification. Hexachlorocyclotriphosphazene (P₃N₃Cl₆), 5-chloro-1-pentyne, 6-iodo-1-hexyne, hydroquinone, β-cyclodextrin (βCD), p-toluenesulfonyl chloride (Cl-Ts), p-toluenesulfonic acid (OH-Ts), N,N-dimethylformamide anhydrous (DMF), potassium carbonate (K₂CO₃), cesium carbonate (Cs₂CO₃), dimethylsulfoxide (DMSO), ascorbic acid (H₂Asc), Bio-Gel P-10 medium from Bio-Rad (Hercules, CA, USA), potassium iodide (KI), sodium azide (NaN₃), sodium hydroxide (NaOH), copper sulfate pentahydrate (CuSO₄•5H₂O), diisopropyl ether, dichloromethane (CH₂Cl₂), ethyl acetate (EtOAc), tetrahydrofuran anhydrous (THF), hexane (HEX), methanol (MeOH), ethanol (EtOH) and acetone (CH₃COCH₃) were purchased from Sigma-Aldrich (St. Louis, MO, USA).

All chemicals were of reagent grade purity and were used without further purification; doubly distilled water passed through a Milli-Q apparatus that was used to prepare solutions and suspensions. Manganese (II) nitrate tetrahydrate (Mn(NO₃)₂·4H₂O, 99%, Sigma-Aldrich, Sigma-Aldrich SRL, Milan, Italy) was the salt precursor; the impregnation procedure required acetone (CH₃COCH₃) (≥99.9%, Sigma-Aldrich, Sigma-Aldrich SRL, Milan, Italy), potassium hydroxide (KOH), and hydrochloric acid (HCl) (reagent grade, 37%, Sigma-Aldrich, Sigma-Aldrich SRL, Milan, Italy) to set the acidic or alkaline pH. Micrometric TiO₂ (by Kronos, identified with the acronym 1077) consists of 100% anatase spherical primary particles of 130 nm, with a surface area of 11 m² g⁻¹, as reported by Bianchi et al. [23 (link)].

Analytical grade chemicals and reagents were used without any further purification. Nitric acid (HNO₃, >69 %, from Breckland Scientific Supplies), Sulfuric acid (H₂SO₄, >98 %, from Breckland Scientific Supplies), Hydrochloric acid (HCl, > 37 %, from Sigma-Aldrich), and Acetone (CH₃COCH₃, >99 %, from Sigma-Aldrich) were used in this study.
