ABSTRACT
A series of photo triggered carbon monoxide releasing molecules was
synthesized from 2 and benzimidazol derivatives (N-N), functionalized
with different electron-donating and withdrawing groups, to afford
octahedral complexes of the type cis-/trans-[RuCl2(CO)2(N-N)]. The
structures of the metal carbonyl complexes were elucidated using
different analytical and spectroscopic tools. The geometrical
stereochemistry around the metal ions was assigned by IR spectroscopy
and quantum chemical calculations. The dark stability in aerated DMSO
and the photoactivatable CO release properties were investigated. With
the aid of time-dependent density functional theory, the influence of the
substituent (type and position on the phenyl ring) on the nature of the
lowest energy transition was investigated.
