Abstract: Plasma polymerization of TCNQ(tetracyanoquinodimethane) was carried out by using acapacitively coupled radio-frequency bell jar apparatus with internal electrodes.Some semi-conductive polymeric films with conductivities ranged from 10^-8 to 10^-6.Scm^-1 were ob-tained.The Al/polymeric film/ITO (indium tin oxide) sandwich cells made of the filmsshowed rectifying behavior and photovoltaic response.Photoconductivity was also observedwith the films.The infrared and ultraviolet spectroscopic results showed that the goodsemiconductive properties are due to the more extended conjugated structure in the films.

Key words: TCNQ, plasma polymerization, semiconductive film, retifying behavior, photovoltaic effect, photoconductivity
