Abstract

Purpose: The aim of this work is to show how electronic properties of polyazomethine thin films deposited bychemical vapor deposition method (CVD) can be tailored by manipulating technological parameters of pristinefilms preparation as well as modifying them while the as-prepared films put into iodine atmosphere.Design/methodology/approach: The recent achievements in the field of designing and preparation methods tobe used while preparing polymer photovoltaic solar cells or optoelectronic devices.Findings: The method used allow for pure pristine polymer thin films to be prtepared without any unintentionaldoping taking place during prepoaration methods. This is a method based on polycondensation process, wherepolymer chain developing is running directly due to chemical reaction between molecules of bifunctionalmonomers. The method applied to prepare thin films of polyazomethines takes advantage of monomertransporting by mreans of neutral transport agent as pure argon is.Research limitations/implications: The main disadvantage of alternately conjugated polymers seems to bequite low mobility of charge carrier that is expected to be a consequence of their backbone being built up ofsp2 hybridized carbon and nitrogen atoms. Varying technological conditions towards increasing reagents masstransport to the substrate is expected to give such polyazomethine thin films organization that phenylene rinstacking can result in special π electron systems rather than linear ones as it is the case.Originality/value: Our results supply with original possibilities which can be useful in ooking for good polymermaterials for optoelectronic and photovoltaic applications. These results have been gained on polyazomethine thinfilms but their being isoelectronic counterpart to widely used poly p-phenylene vinylene may be very convenient todevelop high efficiency polymer solar cells
