Photoswitchable organoplatinum complexes with an azobenzene derivative of di-2-pyridylamine

Author affiliations

Abstract

A new di-2-pyridylamine ligand with an appended azobenzene group (2-C5H4N)2N-4-C6H4-N[double bond, length as m-dash]N-Ph, dpaa, is reported. This ligand readily forms the platinum(II) complexes [PtMe2(dpaa)], 1, and [PtCl2(dpaa)], 2. Complex 1 is electron-rich and it undergoes oxidative addition with I2, MeI or PhCH2Br to give the corresponding organoplatinum(IV) complexes [PtI2Me2(dpaa)], [PtIMe3(dpaa)] or [PtBrMe2(CH2Ph)(dpaa)]. Both the ligand dpaa and its platinum complexes undergo photoswitching by transcis isomerization about the N[double bond, length as m-dash]N linkage.
