A Dendron Based on Natural Amino Acids: Synthesis and Behavior as an Organogelator and Lyotropic Liquid Crystal

From linear to dendritic: Glycine is part of the predominant sequence in collagen proteins, and aspartate is similar to the repeating unit of poly(benzyl glutamate)s (PBG)s. Collagen and PBGs are linear peptides that self‐organize into fibers and form liquid‐crystalline phases and gel solvents. How...

Description
Summary:From linear to dendritic: Glycine is part of the predominant sequence in collagen proteins, and aspartate is similar to the repeating unit of poly(benzyl glutamate)s (PBG)s. Collagen and PBGs are linear peptides that self‐organize into fibers and form liquid‐crystalline phases and gel solvents. How would a molecule self‐assemble if it was built by arranging Gly‐Asp units in a dendritic way (see picture)? A dendron as both gelator and liquid crystal?
