Preparation of Ru(bpy)3Cl2 and APS Solutions

The photoinitiator tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate (Ru(bpy)₃Cl₂·6H₂O) was prepared in the corresponding buffer to a concentration of 5 mM and stored at 4 °C. The electron acceptor ammonium persulfate (APS, chemical formula: (NH₄)₂S₂O₈) was prepared with a concentration of 2 M in the corresponding buffer, stored as aliquots at −20 °C, and thawed directly prior to usage.

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.
