Streamlined and regioselective synthesis of a series of unprecedented [3]naphthylenes, where 3 naphthalenoids are fused through 2 cyclobutadienoids in linear, angular, and bent regio-connectivity. The fusion pattern strongly affected the local antiaromaticity and aromaticity of these compounds, reflected in their distinct optoelectronic properties and bonding structures.

Science, 2017, 357, 475.

Artistically rendered segment of a synthetic macromolecular ladder scaffold, inspired by a natural product structure, that unzips through ring-opening in response to mechanical force. The ensuing mechanochemical metamorphosis of the insulating polyladderene structure into semiconducting polyacetylene nanowires rapidly transforms the material's intrinsic properties and functions.
