Purpose: The aim of this paper is to compare optical properties of 4-(1,1,1,3,3,3-hexafluoro-2(-4(-3(4-(5-(4-m-tolyoxy)phenyl)-1,3,4-oxadiazol-2-yl)phenoxy)phenylcarbomyl)phenyl)propan2-yl)-N-methylbenzamide (Oxad 6F-D) and 4-(1,1,1,3,3,3-hexafluoro-2(-4-(4-(4-(5-(4-(p-tolyoxy)phenyl)-1,3,4-oxadiazol-2-yl)phenoxycarbaomyl)phenyl)propan-2-yl)-N-methylbenzamide (Oxad 6F-E). Design/methodology/approach: The Oxad 6F polymer thin films were deposited onto glass and KBr substrates by spin–coating method under different technological conditions. Findings: The spinning rate V and solution concentration C influenced optical properties of Oxad 6F-D and Oxad 6F-E thin films. The goal of this paper is to show differences in properties of these polymers. Research limitations/implications: The electrical and luminescent properties of Oxad 6F polymers will be carried out in the nearest time. The different properties of these polymers are caused by benzene position in the polymer chain, two aromatic rings are in meta-position in Oxad 6F-D and all benzene rings are in para-positions in Oxad 6F-E. Practical implications: Thin films of Oxad 6F-D and Oxad 6F-E are good potential material for applications in polymer optoelectronic devices. Originality/value: The aim of this paper is to describe the optical properties of Oxad 6F polymers prepared under different technological conditions.

Purpose: The major aim of this paper was describing technical conditions of polymer thin film deposition by spin-coating techniques. Design/methodology/approach: Thin films of about nanometres thickness were prepared by spin-coating and their properties were studied. As a material for preparing polymer thin films oxad-Si was used. The thin films were deposited with various spinning velocity from solution of different concentration. Thin films were deposited on BK7 glass and quartz substrates. Findings: The obtained results describe influence of the solution concentration and spinning velocity on morphology and optical properties of spin-coated oxad-Si thin films. Research limitations/implications: The obtained results confirm the oxad-Si availability for optoelectronic application to be stipulated. Practical implications: The morphology and optical properties of Oxad-Si polymer thin films were described. This paper include also description of the influence of deposition conditions on properties of polymer thin films. Originality/value: The value of this paper is defining the optimal parameters of spin-coating technology for preparing oxad-Si thin film with the best properties for optoelectronics appliances. This paper describes new experimental polymeric material for spin coating technology. Results of these researches enable to develop the spin-coating technology.
