Twisted intramolecular charge-transfer fluorescence of aromatic amides: conformation of the amide bonds in excited states

Steady-state and Time-resolved Spectroscopic Studies of Benzanilides

“…This dependence was proved by other authors [14,15]. The T value obtained for I in MCH at room temperature and at 77 K is in good agreement with the results of [16] and [17].…”

Atropisomerism in the Vaptan Class of Vasopressin Receptor Ligands: The Active Conformation Recognized by the Receptor

“…Thus, the major isomer of 2 A (racemate and enantiomers) exists in a cis arrangement in solution as well as in the solid state. This is consistent with the report [13] that N-benzoyl-N-methylanilines exist in a cis structure. Similar structural features were observed for 2 B, 3 A, 3 B, 4 A, and 4 B as for 2 A.…”

Conformation and stereodynamics of 2,2′-disubstituted N,N′-diaryl ureas

“…9 N-Methylation of aromatic amides and ureas has been proposed as a general strategy for control of conformation about the C-N bonds of such compounds, since it leads to structures in which close Ar-Ar contacts are prevalent. [10][11][12][13] However, little detailed work has been reported on the conformational preferences of simple mono-ureas, despite the fact that the helicity of an oligourea is dependent on the adoption by each individual urea linkage of a well-defined local conformation.…”
