The main goal of this thesis was to synthesize and investigate the spectroscopic, electrochemical and electrical transport properties a new well-soluble arylene bisimide derivatives (Scheme 1). The three compounds studied (naphthalene bisimides containing  p-butoxy- (1 ), p-hexyloxy- (2 )and p-octyloxyphenylene (3 )N-substituents), were prepared by condensation reaction of p-alkoxyaniline with naphthalene dianhydrate. The UV � vis spectra of all compounds seems to be similar and they are dominated by a strong band of a pronounced vibronic structure, ascribed to the p-p* transition in the arylene core with most intensive 0-0 vibronic peak (380 nm). Cyclic voltammetry and preliminary results in designing transistors predict that these semiconductors yield field effect in the n-channel configuration. As evidenced by STM in monolayers they form ordered 3D structures, whereas film of compounds 1-3 are highly crystalline. The powder and film X-ray profiles of all semiconductors were also compared.
