Abstract

The CV curve for 3 recorded¶ between +2.7 V and −3 V is shown in Fig. 1. The reduction potentials (−1.94 V and −2.3 V) correspond to reduction at the quinoline moiety and acetylene function respectively. 16,17 The positive potential at +1.71 V is ascribed to oxidation at the methoxyphenyl site (for 4–8 the donor is the N,N-dialkylaminophenyl moiety and they show similar oxidation potentials 0.85–1.05 V). The first reduction and oxidation potentials which correspond to ...
