| Abstract [eng] |
Tröger's base is V-shaped C2-symmetric chiral molecule consisting of a bicyclic aliphatic methanodiazocine unit fused with two aromatic rings, their planes nearly perpendicular to each other. Such structure of rigid V-shaped molecular scaffold allows it be used as a core and provide angle orientation for the substituents, such as conjugated π-systems, attached to it. It was as well reported that, besides connecting aromatic fragments only geometrically, the non-conjugated bridge in Tröger’s base can bestow electronic coupling for conjoined fragments in the absence of a π-linker. Hence, Tröger's base offers itself as a unique, nanometer-sized building block for unusual molecular design, granting the possibility to bestow compounds with desired, yet uncommon, properties. Although Tröger’s base is already well studied and found applicability in different areas, its use in optoelectronics was not widely described, leaving this field for further investigation and discovery. Hence, the work presented in this dissertation is the synthesis and investigation of novel functional Tröger’s base compounds for optoelectronic applications: charge generating double-acceptor dyes for dye-sensitized solar cells, solid state light emitting Tröger’s base derivatives for OLEDs, and well performing amorphous hole transporting materials for perovskite solar cells. |
