Incremental Introduction of Organocatalytic Activity into Conformationally Engineered Porphyrins
(2019)To study the correlation of macrocycle nonplanarity and catalytic activity of free base porphyrins in detail, a series of six tetraphenylporphyrins with graded degree of β‐ethyl substitution (“H2EtxTPPs” 1–6; x = 0, 2, 4, ... -
Molecular Engineering of Free-Base Porphyrins as Ligands-The N-H? ? ? X Binding Motif in Tetrapyrroles
(2019)The core N-H units of planar porphyrins are often inaccessible to forming hydrogen-bonding complexes with acceptor molecules. This is due to the fact that the amine moieties are “shielded” by the macrocyclic system, ... -
Molekulares Engineering freier Porphyrinbasen als Liganden – das N-H···X-Bindungsmotiv in Tetrapyrrolen
(2019)Die N‐H‐Einheiten im Kern planarer Porphyrine sind oft nicht zugänglich, um Wasserstoffbrückenkomplexe mit Akzeptormolekülen zu bilden. Dies liegt daran, dass die funktionellen Aminogruppen durch das makrozyklische System ...
