DFT calculations carried out on trans-decahydronaphthalene and 4b,8b-dihydronaphthalene, important structural features of many alkaloids, revealed that they are moderately acidic carbon acids in the gas-phase and in DMSO solution. Substitution with a nitrogen atom of a neighbouring C(sp)–H fragment bonded to an acidic centre reduces the corresponding acidity in both phases. Following that, oxid...

Carbon super-heterostructures with high nitrogen contents from the covalent hybrid precursors of triazine frameworks (CTFs) and zeolitic imidazolic (ZIFs) are scarcely explored because CTF's ordered structure toxic superacid that dissolves or destabilizes metal nodes. To solve this problem, herein, we report a straightforward two-step pathway for hybridization disordered CTF (d–CTF)–ZIF composi...
