Photoactive metal complex

Among what have been widely employed as model compounds for Chi, are porphyrins, phthalocyanines, and some photoactive transition metal complexes, which are more stable and easier to obtain than Chi. Interfacial layers of these insoluble compounds are generally prepared by means of vacuum sublimation or solvent evaporation.

To get inside the oxidative damage of DNA caused by photoactive ruthenium(II) intercalators, complexes can be attached to one end of double-stranded DNA. The great advantage of this method is that intercalation of tethered metal complexes takes place at a defined distance from the oxidation site. The ruthenium(II) complex of the type [Ru(bpy )(Me2dppz)(phen)]2+ (structure of ligands presented in Figure... 

Dyads and triads based on the photoactive, multibridging [Ru(bpz)3] (bpz = bipyrazine) complex directly bound to transition metal complexes were obtained by following the procedures previously reported for the generation of symmetric heptanuclear supermolecules (67-69). Such systems contain a tris(bpz)ruthenium (II) ion [RuJ attached to bis(bpy)chlororuthenium(II)/(III) [Rup], or penta-cyanoferrate(II)/(III) complexes via a bpz bridging ligand, as shown for the... 

Herein, we wdl discuss several approaches that have led from molecular entities to supramolecular soft and hard systems. In particular, we will show how the molecular structure can be modified to induce the controlled self-assembly of transition metal complexes into sophisticated photoactive arrays with imusual properties derived from the structiu-e of the metal complexes and their intermolecular interactions in the ground and/or excited electronic states within the assemblies. We will start with a survey of the photophysical properties of selected transition metal complexes, followed by an overview of the aggregation mechanism they can undergo to. We will focus our attention on soft assemblies... 

A large number of synthetic multimetal complexes have been prepared as potential photoinduced electron-transfer systems [53]. In these designs the metal complexes can act both as structural templates and as photoactive units in their own right.

A photoactive metal center is introduced in these systems. The ruthenium bipyridyl complexes are coordinated to the emeraldine base to form the corresponding polymer complexes as described above." The incorporation of the ruthenium centers to the pyridyl backbone has been also reported to give the ruthenium complexes Conjugated ruthenium bipyridine complexes thus obtained are evaluated to be photorefractive materials. Other transition metal complexes can be employed to form the corresponding polymer complexes. The pyridine unit is replaced by bithienyl, 1,4-diazabutadiene, ethylene, benzimidazole or thiazole. ... 

This chapter reviews the major advances in the field of photochemistry and photocatalysis by transition metal compounds published in 2013-2014. Particular attention has been given to (i) photocatalysis in synthesis, and in the conversion of sunlight energy into chemical energy (ii) photoreactivity (iii) biomedical applications of photoactive transition metal complexes, e.g. as photo-CORMs and PDT agents.
