Abstract

The optical properties of 2,2′7,7′-tetrakis-(N,N-di-p-methoxyphenyl amine)-9,9′-spirobifluorene (spiro-MeOTAD) in Chlorobenzene have been investigated by UV-Vis spectroscopy. Spiro-MeOTAD is a small molecular high performance hole transport material widely used in many optoelectronic devices. Spiro-MeOTAD dissolved in Chlorobenzene reveals two absorption bands at ~ 300 and 390 nm. The thin-films have been fabricated by depositing Spiro-MeOTAD onto glass using the spin-coating method. In thin-film samples, it is found that a prominent narrow absorption peak emerges at ~ 240 nm with a broad band at ~380 nm. The film fabrication method and optoelectronic properties will be presented.
