Porphyrins are variously substituted tetrapyrrolic macrocycles, with wide-ranging biological
and chemical applications derived from metal chelation in the core and the 18π aromatic …

Tetraphenylporphyrin (H 2 TPP) and zinc tetraphenylporphyrin (ZnTPP) are widely used
benchmark molecules in diverse photochemical studies given facile synthetic access, rich …

“Anything that exists must be possible.” is often referred to as KE Boulding's First Law. 1 For
example, nanoscale photonic devices exist that harvest light and convert it to …

Extensive time‐dependent DFT (TDDFT) and DFT/multireference configuration interaction
(MRCI) calculations are performed on the singlet and triplet excited states of free‐base …

Different porphyrin conformations are believed to play a role in controlling the cofactor
properties in natural tetrapyrrole-protein complexes. In order to study the correlation …

The photophysical properties of the lowest excited singlet states, S1 (π, π*), of two porphyrin
diacids have been investigated. The diacids are H4TPP2+ and H4OEP2+, the diprotonated …

Two noncovalent nanohybrids between cationic porphyrin (free-base TMPyP and zinc (II)
ZnTMPyP) bearing cationic (N-methylpyridyl) groups and graphene oxide (GO) were …

A recently developed method of synthesis of π-extended porphyrins made it possible to
prepare a series of tetrabenzoporphyrins (TBP) with different numbers of meso-aryl …

Previous studies of 5, 10, 15, 20-tetraarylporphyrins have shown that the barrier for meso
aryl− porphyrin rotation (Δ G‡ ROT) varies as a function of the core substituent M and is …

Zinc and palladium tetracyclic aromatic complexes lying structurally between
tetraazaporphyrin (TAP) and phthalocyanine (Pc), that is, monobenzo‐, adjacently dibenzo …
