Original Title:
Σύνθεση και χαρακτηρισμός συμπλόκων του χαλκού (Ι). Μελέτη της δράσης τους ως φωτοευαισθητοποιητών σε συστήματα φωτοκαταλυτικής παραγωγής υδρογόνου και σε φωτοευαισθητοποιούμενες ηλιακές κυψελίδες.
Translated title:
Synthesis and characterization of copper (I) complexes. Study as photosensitizers in photocatalytic hydrogen production systems and in dye sensitized solar cells.
Summary:
This work was conducted within the MSc thesis in the field of Inorganic Chemistry and Industrial Applications, at the Inorganic Laboratoty of the Chemistry Department of University of Athens. In the present thesis, we present the synthesis of the homoleptic bisdiimine copper(I) complex [Cu(BCDS)2]BF4 and the heteroleptic diimine-diphosphine copper(I) complex [Cu(BCDS)(dppe)]BF4, where BCDS = bathocuproinedisulfonic acid disodium salt and dppe = 1,2 bis(diphenylphosphino)ethane, containing sulfonate anchor groups for their immobilization on metal oxide surface and designed to exhibit cooperative steric hindrance. The aforementioned complexes have been characterized by FT-IR, Raman, UV-Vis, NMR, emission spectroscopy and cyclic voltammetry (CV) and their photophysical and electrochemical behavior have been studied and discussed. Both complexes are tested as photosensitizers in homogeneous and microheterogeneous photocatalytic hydrogen evolution systems. For the detection of H2 a gas chromatographer with a thermal conductivity detector (TCD) was used. Their efficiencies as dyes in dye sensitized solar cells with TiO2 semiconductor and I3-/I- redox couple in acetonitrile are also evaluated and compared to the benchmark commercial Ru(II) dye N719.
