Control of aggregates and their colors of acene molecules in the solid state utilizing self-assembly of alkyl side chains

烷基侧链具有形成自聚集的能力。我们比较了一系列具有烷基侧链的新型四茂铁分子，以期通过烷基侧链来控制分子的排列和固态的光物理性质。我们观察到烷基侧链的形状和位置，进一步混合异构体可以调节色调和荧光量子产率。我们得出结论：烷基侧链是控制固体光学性质的关键因素之一。

Alkyl side chains have abilties to form self-aggregations. We have parepared a series of new tetracene molecules having alkyl side chains so as to control molecular arrangements and photophysical properties in the solid state by alkyl side chains. We observed that the shape and position of alkyl side chains, further mixing isomers could tune color tones and fluorescence quantum yields. We concluded that the alkyl side chain is one of critical factors to control the solid-state optical properties.
