Figure 3: Ultraviolet-Vis absorption and ECD spectra.

From: A switchable self-assembling and disassembling chiral system based on a porphyrin-substituted phenylalanine–phenylalanine motif

Figure 3

Blue traces are from the natural dipeptide conjugate X-FLFL-TPP while red traces are from X-FDFD-TPP with X=Boc (a) and X=Fmoc (b,c). (a) Self-assemblies obtained by injecting 3 μl of Boc-FF-TPP from a stock solution (2.8 mg dissolved in 350 μl dry dichloromethane) into dry n-heptane (400 μl). (b) Self-assemblies obtained by injecting 3 μl of Fmoc-FF-TPP from a stock solution (2.8 mg dissolved in 330 μl dry dichloromethane) into dry n-heptane (400 μl). (c) Film on the cuvette walls from the same cuvette as in b after decanting the solution. Supplementary Fig. 20 presents the corresponding spectra of unprotected FF-TPP.
