Hard and straight: Diamond is the hardest material known, yet polyyne—a molecular rod comprised of CC units—resists longitudinal compression with a Young's Modulus 40 times larger than diamond, whereas [ n ]staffanes have a Young's Modulus close to that of diamond. Mechanical engineering provides the connection between the point at which a rod buckles under longitudinal load and its cross‐sectional area.
