Four perfluorohexyl carbinols have been prepared from the corresponding Grignard reagent and benzaldehyde, terephthalaldehyde, isophthalaldehyde, and trimesaldehyde. The corresponding secondary alcohols were then transformed by alkylation and acylation reactions to form a total of 14 ethers (methyl, ethyl, propyl, and n-hexyl ethers) and esters (acetyl and 2-ethylhexanoyl), respectively. Furthermore, 11 perfluoroalkyl carboxylates were prepared from aromatic, heteroaromatic, and aliphatic mono-, di-, tri-, and tetracarboxylic acids and tridecafluorooctanol. The wettability of all 29 materials was investigated by the water contact angle measurements of thin films on glass surfaces. In up to six cases, contact angles greater than 130° were observed, which indicates that the products might be suitable candidates for the impregnation of surfaces. With their relatively short perfluoroalkyl side-chains and therefore low bioaccumulativity, the target compounds might be beneficial alternatives to established products.
