Thermochromic Behavior of Polydiacetylene Nanomaterials Driven by Charged Peptide Amphiphiles.

The peak position of the red phase shows a decreasing trend with temperature with the same rate in peak position change, suggesting that this is most likely associated with the inherent temperature-dependent behavior and not due to the disorder ( Figure 6 c,d,g,h,k,l). 47 In addition, the RGB analysis of the films during the temperature-dependent studies suggests that the peptide-PDA samples become more red with the increasing temperature, and the amount of the blue component remains relatively unchanged across the different temperatures ( Figure S19 ).
