Mono-copper far more active than analogous di-copper complex for electrocatalytic hydrogen evolution

Abstract
O, in MeCN with 80 equivalents of acetic acid, revealed it was inactive, in stark contrast to the high and ongoing activity of 1 under the same conditions. So two is definitely not better than one metal ion in this case. Rather, it may be that the presence of an NH group in the macrocycle of 1, but absent in the bis-macrocycle of 2 (due to alkylating that NH to link the two macrocycles), may be key to the HER activity seen for 1.
