Studying of polyoxadiazolo with Si atom in the backbone

摘要

Purpose: The aim of this paper is to show properties of spin-coated thin films of new polymer having siliconatom in the backbone. This amorphous polymer has appeared to be applied as active films in organic devices (asOLED). Design/methodology/approach: Thin films of 4-(diphenyl(4-(4-(5-(p-tolyoxy)phenyl)-l,3,4-oxadiazol-2-yl)phenyloamino)methyl)-phenyl)silyl)-l-methylbenzamide (Oxad-Si-B) were obtained by spin-coating method.The methodology of preparing was changing of technological parameters such as solution concentration andspinning rate V. The films were deposited with five spinning rates. Findings: Such technological parameters as spinning rate and solution concentration has appeared to influence optical properties of thin films. These parameters were found to influence surface morphology and UV-Vis absorption spectra of thin films. Research limitations/implications: The optical properties of obtained films will allow further researches of this polymer. Its optical properties allow carrying of electrical measurements, which will be carried out in the nearest time. Practical implications: The value of Oxad-Si (B) energy gap suggests its luminescent properties and applications of this material as active film in optoelectronic devices. Originality/value: The goal of this paper is to show optical properties of thin films prepared with most optimal technology conditions.
