Outline of Research at the Start |
有機薄膜デバイスの分野では,活性層に使われる有機半導体材料の構造-物性相関を明らかにすることが重要課題となっており,有機薄膜中の結晶および分子の配列を正確に解析する技術が求められている.赤外多角入射分解分光法(MAIRS)は,機能性有機薄膜の分子配向解析手法として,近年,大きな注目を集めている.しかし,この手法は,“透過光学系”で測定を行うために,使用する基板が赤外光に対して透明な基板に限られるなどの実験的制約がある.本研究では,ガラス基板や金属電極を含む実際のデバイス素子の測定を可能にする“反射型MAIRS”の開発を行う.

Outline of Final Research Achievements |
Infrared multiple-angle incidence resolution spectrometry (MAIRS) has attracted much attention in recent years as a spectroscopic tool for structural analysis of functional organic thin films. While this method can be easily measured using commercially available FT-IR spectrometers, it has the experimental limitation of using only substrates transparent to infrared light because the measurements are performed with transmission optical systems. This makes it difficult to directly measure practical thin-film devices that incorporate glass substrates and metal electrodes. To overcome these difficulties, a new MAIRS technique was developed in this research.

Academic Significance and Societal Importance of the Research Achievements |
有機エレクトロニクスの分野では,有機半導体に高度な分子設計が施される一方で,薄膜デバイスの性能に直結する,分子凝集構造を正確に把握するための測定技術が不足している.このような状況の中,本課題で開発した反射型MAIRSは,有機薄膜の新たな構造解析手法として,高効率な薄膜デバイスの開発を大きく前進させる可能性を秘めている.
