a. 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.
b. 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.
