Visualizing stepwise evolution of carbon hybridization from sp 3 to sp 2 and to sp
Published 2025-01-01“…Utilizing scanning probing microscopy, we distinguish three distinct carbon-carbon bond types within polymers induced by annealing at elevated temperatures. Density-functional-theory calculations unveil the pivotal role of the electron-withdrawing cyano group in activating neighboring methylene to form C(sp 3 )–C(sp 3 ) bonds, and in facilitating subsequent stepwise HCN eliminations to realize the transformation across three carbon-carbon bond types. …”
