Quinoxaline-annelated hexadehydro[12]annulene: use of a new building block to construct a hydrogen-bonded hexagonal molecular network

A new hexatopic carboxylic acid with a quinoxaline-annelated hexadehydro[12]annulene core (TQ12) was synthesized and subjected to spectroscopy for comparison with a tribenzohexadehydro[12]annulene derivative (T12). Subsequently, TQ12 was utilized for the construction of a hydrogen-bonded hexagonal molecular network, which showed rich HCl responsivity.

Automated summary

A new compound TQ12 with a quinoxaline-annelated hexadehydro[12]annulene core was synthesized and compared with T12. TQ12 was then used to construct a hydrogen-bonded hexagonal molecular network with rich responsiveness to HCl.
