Stackable Aromatic Dipeptide Ring Structures toward Nanotube Formation: Thermodynamics and Interactions in Gas‐Phase and Solution

Luminescent and morphological behavior of the aromatic dipeptide pair having singular structural variability

In the present manuscript, the luminescence and the self-assembly behavior of the two aromatic dipeptides having singular structure variable are investigated. The terminally protected dipeptides tryptophan-tyrosine (WY^p ) and tryptophan-phenylalanine (WF^p ) were synthesized using standard solution phase procedure. Significant solvatochromic effect was observed for both the dipeptidyl entities; while the influence was more pronounced in case of the WY^p entity when compared to WF^p . Interesting morphological variation was observed for WF^p and WY^p , wherein discrete and interconnected nanospheres were observed for the respective dipeptides. The results obtained signifies the influence of the singular structural variation on modulating the overall functional behavior of the short peptides motifs.
