Synthesis of Structurally-organized Organic Solids using Subsitutent-modified Tetracenes and their Optical Properties

以四烯或其他多环芳烃分子为发色团的新型有机分子，阐明了通过引入取代基改变分子排列和调节固态光学性质的机理。研究了固体吸收光谱和x射线晶体学分析。我们得出结论，取代基的长度和位置显著影响光学性质和包装结构，而发色团的重叠是最有效的调整固态颜色。

To clarify the mechanism of changing molecular arrangement as well as tuning the solid-state optical properties by the introduction of substituent groups, new organic molecules that have a tetracene or other polycyclic aromatic hydrocarbon molecules as chromophore. Absorption spectra in the solid state and X-ray crystallographic analysis were examined. We concluded that the length and postion of substituents significantly effected optical properties and packing structures, and that overlap of chromophores was the most effective to tune the solid-state color.
