Genetic code expansion for chemosensing and chemical actuation of biological functions

Bulletin of the Korean Chemical Society, EarlyView.
Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.

Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex

Chemistry – A European Journal, EarlyView.
Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.
