While in nature, molecular chirality enables the formation of chiral macroscopic structures through crystallization and self-organization, such a transfer of molecular information to higher hierarchical levels is rarely observed in vitro. Here, the study reports on single crystals of microbially synthesized polyester poly[(R)-3-hydroxybutyrate], which have chiral habits when grown at the air-water interface, in analogy to the 2D crystallization of chiral lipids such as DPPC. Depending on the crystallization conditions, the chiral single crystals either undergo a transition into fiber-like structures, orassemble into larger superstructures with a uniform sense of rotation.
Keywords: chirality; langmuir film; poly[(R)‐3‐hydroxybutyrate]; polymer single crystal.
