#### Scholarcy highlights

• First-principle calculations were conducted on porous graphene structures to compare the properties of a polyphenylene super-honeycomb network with those of an oxygen-terminated PSN obtained from oxygen substitution
• The band structures, densities of states, and simulated STM images were presented along with the infrared and Raman spectra, which could distinguish the properties of O-PSN from PSN
• Our results showed that the two oxygen atoms replacing the hydrogen atoms tend to be separated as far as possible at the PSN pores
• Our results showed that the two oxygen atoms replacing the hydrogen atoms tend to be separated as far as possible at the polyphenylene super-honeycomb network pores
