Proton Affinities of Didehydroporphyrin and Subporphyrin in Ground and Excited States Obtained by Quantum Chemical Calculations [PDF]

open access: yes, 2009
Quantum-chemical calculations were used to investigate molecular and electronic properties of porphyrin and subporphyrin. Their basicities were estimated in ground and excited states.

Exploring antiaromaticity in single-molecule junctions formed from biphenylene derivatives.

open access: yesNanoscale, 2019
We report the synthesis of a series of oligophenylene-ethynylene (OPE) derivatives with biphenylene core units, designed to assess the effects of biphenylene antiaromaticity on charge transport in molecular junctions.

Fully Conjugated Heteroatomic Non- and Quasi-Alternant Polyradicals

open access: yesChemistry
In this work, we present fully π-conjugated diradical(oid)s and tetraradical(oid)s with five-membered non-alternant cyclopentadienyl and quasi-alternant thiophene rings, the latter of which is used as a source of aromatic stabilization.
