WebThe covalent bond is formed by sharing of electrons. There is an atomic orbital overlapping occurring in two bond-forming atoms and a sigma bond is formed. The bond length is small, hence the influence of attractive force is greater and atoms get closer with each other. WebHoje · By contrast, the exploration of proton conduction in COFs, a family of crystalline porous organic materials, has revealed their prominent advantages [51], [52], [53], [54].In detail, COFs are composed of light elements (e.g., C, O, N, etc.) and have stable covalent bonds, resulting in high chemical/thermal stability, low mass density, wide pH tolerance, …
