Acetelynic polymers have received considerable attention due to their electronically unsaturated and highly conjugated structures, which have led to numerous discoveries in specialty polymers with tunable electronic properties. Compared to vinylene-linked polymers, ethynylenes form more rigid and shape persistent linear bonds, where their alkene analogs must deal with regioselectivity and rotational freedom about the double bond. It has been realized that due to the unique characteristics of ethynylene-based polymers, these systems hold unique electronic and optical properties that would be very difficult to mimic by their olefinic counterparts. However, till now the ethynylene-linked polymers are still mainly limited to 1D linear ones. The development of 2D and 3D conjugated polymeric architectures would open many new possibilities for electronic, thermoelectric, and optoelectronic materials development for light harvesting, energy storage, and sensing applications. This presentation will focus on the design and synthesis of two carbon-rich conjugated aromatic frameworks using dynamic imine and alkyne metathesis chemistry. The electron- and/or ion-conductivity of the resulting polymers, as well as their potential in energy storage application, will also be discussed.
