Reversible “Chiral Memory” in Ruthenium Tris(phenanthroline)–Anionic Porphyrin Complexes

Abstract

In this communication all the CD signals of the lamda isomer have been inadvertently swapped with those of the delta isomer and vice versa. The authors apologize for these errors and wish to note that none of the interpretations in the paper are affected by this change.

Chaperone-like chiral cages for catalyzing enantio-selective supramolecular polymerization

“…Traditional supramolecular polymerization of tetrakis(4sulfonatophenyl)-porphyrin (TPPS, structure shown in Fig. 1C) was selected as a representative non-covalent assembly system [47][48][49][50][51][52][53][54][55] to be catalyzed by chiral cages. Supramolecular polymerization of TPPS has previously been regulated through a co-assembly method by adding oppositely charged chiral auxiliaries, such as amines 56 and amino acids.…”

Homochiral self-assembly of biocoordination polymers: anion-triggered helicity and absolute configuration inversion

“…In particular, the appearance of homochirality in biological systems, which is likely related to the origin of life, 7 is still largely unclear. A chiral coordination complex or polymer can be obtained either in a rational way, by a judicious choice of chiral enantiopure ligands or “chiral auxiliaries” capable of transmitting their “chiral information” to the stereochemistry of the metal atoms, 8 or serendipitously, when so-called spontaneous resolution processes 9 occur. In this regard, interesting works have been reported recently pointing towards external factors as responsible for these spontaneous resolution processes ( e.g.…”

Supramolecular chirogenesis in zinc porphyrins by enantiopure hemicucurbit[n]urils (n = 6, 8)

“…[14][15][16] Nevertheless, porphyrin aggregates formed in aqueous media also exhibit intense ICD signals. [17][18][19][20][21][22][23][24] Chiral macrocycles, cyclohexanohemicucurbit[n]urils (cycHC [6] and cycHC [8], see Fig. 1A), have complementary dimensions with porphyrins, with their height being close to a nanometer.…”
