Fig. 4. (A) Absorption (10−5 to 10−6 M) and emission spectra (10−6 to 10−7 M) of 1–4 in CH2Cl2; (B) frontier molecular orbitals of 3 and 1 (PW6B95-D3(BJ)/def2-QZVPP//PBEh-3c); (C) cyclic voltammograms of 1 and 2 (negative potential range in THF, positive in CH2Cl2, 1 mM concentration, 0.1 M n-Bu4NPF6, scan rate 0.2 V s−1, glassy carbon electrode, potentials plotted vs. Fc/Fc+ as internal standard).
