Novel phthalocyanines and their complexes with transition metals

Phthalocyanines are a family of compounds with interesting optoelectronic properties. When combined with a transition metal at the centre, they provide suitable candidates for energy transfer and applications including dyes, photosensitizers, catalysis etc. These large π-delocalized and almost planar structures have been studied by theoretical methods of high quality.

In collaboration with the experimental group at the Inorganic Chemistry Laboratory of the University of Athens and Dr G. A. Mousdis at NHRF, we have studied numerous newly synthesized compounds, elucidated their structures and assisted in the assignment of their spectra, especially UV-Vis and IR.

Transition metal complexes with interesting electronic properties and indirect metal metal interaction

Dinuclear and Trinuclear tetrathiometalate complexes were synthesized involving Rh, Mo, W and Cu. The special interest concerning these bimetallic and trimetallic anionic complexes lies on the interesting properties of electronic nature they exhibit, i.e. the electronic communication between the metal centers and also the correlation of the UV-vis band maxima with the type of phosphate ligands.

DFT calculations performed by our group reveal the nature of such long range (meaning that there is no direct bond) metal-metal interaction, as well as extended π-systems involving the S bridges.
