Absorption and emission spectra of purified conjugates and the native MPc dyes. (a) Electronic absorption spectra of 2 (2 μM) in NH4OH (pH 11) (···), 2-C12-O1 (concentration unknown) in NH4OH (pH 11) (—), and 2 (2 μM) in DMSO (· – · – ·); (b) Fluorescence emission spectra (λex = 650 nm) of 1 (100 nM) in NH4OH at pH9/MeOH (50/50) (· – · – ·), conjugate 1-C12-O1 (concentration unknown) in NH4OH at pH9/MeOH (50/50) (···), 2 (100 nM) in carbonate buffer at pH11/MeOH (50:50) (---) and 2-C12-O1 (concentration unknown) in carbonate buffer at pH11/MeOH (50:50) (—).
