European Journal of Inorganic Chemistry, EarlyView.A new family of phosphorescent Pt(II) complexes with pyrimidinedipyrrolide ligands, including a pyrazine analog, was designed and synthesized. Their emission properties can be finely tuned via ligand modification, revealing strong phosphorescence originating from intraligand charge transfer transitions.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
