Electrical resistivity measurements were made for pure and doped PMMA films with TCNQ-anthracene, Li-TCNQ charge transfer solid complexes and a TCNQ-anthracene donor-acceptor system. The effect of concentration of the dopant, temperature, and light on the electrical behavior of these films was investigated and is discussed. The ultraviolet and visible spectra were also studied. The sensitivity of the PMMA doped films for photoconductivity is discussed on the basis of the conduction mechanism proposed for the charge transfer interaction in the complex systems.
