Tetrachloroauric(III) acid (HAuCl4) and sodium ascorbate citrate (C6H7NaO6) were purchased from Sigma-Aldrich (Saint-Louis,
MO). Silver nitrate was purchased from VWR Chemical (Radnor, Pennsylvania).
All solutions were prepared with HPLC-grade water (Lichrosolv) and
all reagent solutions were aqueous unless otherwise noted. Calix[4]arenes
C1 and C2 were purchased from X4C (Belgium). Before use, all glassware
and Teflon-coated stir bars were washed with aqua regia (3:1 volume
ratio of concentrated HCl and HNO3) and rinsed thoroughly
with water.
Caution! Although we have not encountered any problem,
it is noted that diazonium salt derivatives are potentially explosive
and should be handled with appropriate precautions. Aqua regia is
highly toxic and corrosive and requires proper personal protective
equipment. Aqua regia should only be handled in a fume hood.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
