Carbon-carbon single bonds are one of the most important bonds in natural/artificial organic molecules and materials. Generally, they are regarded as being strong, irreversible, and static covalent bonds. However, chemical modification around the C–C bonds including the introduction of steric hindrance, electronic effects, and resonance stabilization can drastically lower their dissociation energies. One extreme example … Continue reading Self-healing And Mechanochromic Polymers With Dynamic Carbon–Carbon Covalent Bonds
