This diploma thesis is focused on study of electric and optoelectric properties of conjugated polymers. The theoretical part describes the relationship between molecular structure of conjugated materials and their chosen macroscopic physical properties like absorption of visible and ultraviolet radiation, electrical conductivity and photoconductivity. This part also describes photochromism and its utilization for construction of light driven current switch. The experimental part studies this switch based on change of photochromic species dipole moment dispersed in conjugated conducting polymer. The active switching unit is represented by photochromic spiropyran 1’,3’-dihydro-1’,3’,3’-trimethyl-6-nitrospiro[2H-1-benzopyran-2,2’-(2H)-indol] which is dispersed in conjugated conducting polymer poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1,4-phenylene-vinylen]. The influence of the photochromic conversion on the polymer matrix was studied by absorption spectroscopy, current-voltage measurements and spectrally resolved steady state photoconductivity and transient photoconductivity.
