p-Phosphonic acid calix[8]arene mediated synthesis of ultra-large, ultra-thin, single-crystal gold nanoplatelets

Author affiliations

Abstract

Single-crystal Au nanoplatelets, as large as 28 μm in cross section and as thin as 6 nm, are generated by bubbling hydrogen gas into an aqueous solution of HAuCl4 in the presence of p-phosphonic acid calix[8]arene, which acts as both a catalyst and stabiliser. The use of the ultrathin Au nanoplatelets in oxygen gas sensing has also been established.
