Conducting two-dimensional polymers (C2Ps) have emerged as a new functional polymer material with unique chemical and physical properties. This is due to their extended pi-conjugation over the second dimension. However, C2Ps with fused aromatic linkages remain unexplored because they are hindered by strong stacking between adjacent layers.
Graphene has attracted intense research interest because of its compelling properties. These include remarkably high thermal conductivity, high mechanical strengths, and high mobility of charge carriers. A study even confirmed that graphene superlattices exhibit unconventional superconductivity.
Known as the "dream material," graphene exhibits electron mobility 140 times faster than silicon and a strength 200 times greater than steel. However, graphene lacks a band gap, vital for regulating electrical current. This prevents graphene from being used as a semiconductor.
Scientists have been actively exploring different strategies to create a semiconductor that demonstrates graphene's exceptional properties. One promising approach is the development of conducting polymers.
