Abstract
The luminance and electronic properties of two distyrylbenzene derivatives with poly(alkyleneoxy) and multi-alkoxy end groups were investigated. The materials exhibit similar UV-visible absorption and photoluminescent properties in solution, but the emission wavelengths in solid thin films are quite different. The reduced red-shift in one of the distyrylbenzene derivatives when forming a solid thin film is attributed to the reduced interaction between the π-electrons of the neighboring molecules by the "bulky" or "spacer"end-groups formed by the methoxy and poly(alkyleneoxy) substituents.
