In the last two decades organic dyes and organic semiconductors get increasing attention due to the high molecular variability and the resulting wide applicability. For example in promising light-activated cancer therapy (Photodynamic Therapy PDT), where near-infrared light absorbing molecules produce reactive oxygen species by energy transfer which leads to cell death. Another application are dye sensitized solar cells (Grätzel cells). Naphthalocyanine-variations were synthesized and tested for their suitability as photosensitizer in Photodynamic Therapy with optical spectroscopy. The newly synthesized four different metal-naphthalo-derivates differ in axial and peripheral anchoring groups. The influence of different amount of nitrogen and tert-butyl or mesityl groups was tested. Different newly sensitized organic molecules (derivatives of Phthalocyanine) were characterized optically and tested for application in Grätzel cells. The impact of different substrates like titanium dioxide (TiO2) and zinc oxide (ZnO) will be discussed. Time Resolved Photoluminescence was performed on this newly processed solarcells.
