分子材料的静态极化率:环境和振动的贡献

Static polarizability of molecular materials: environmental and vibrational contributions

Francesca Terenziani, Anna Painelli, Zoltan G. Soos

摘要:

由大π共轭分子组成的分子材料的介电行为的建模是一个有趣而复杂的任务。在这里,我们地址的线性极化率,和相关的介电常数,分子晶体和聚集体组成的封闭壳π共轭分子与非极性或极性基态,也检查的混合价(或电荷转移)的有机盐的行为。我们认识到重要的集体现象,由于超分子相互作用的材料具有大的分子极化率,并强调大的振动贡献的极化率在很大程度上离域电子的材料。

英文摘要:

Modeling the dielectric behavior of molecular materials made up of large pi-conjugated molecules is an interesting and complex task. Here we address linear polarizabilities, and the related dielectric constant, of molecular crystals and aggregates made up of closed-shell pi-conjugated molecules with either a non-polar or largely polar ground-state, and also examine the behavior of mixed-valence (or charge-transfer) organic salts. We recognize important collective phenomena due to supramolecular interactions in materials with large molecular polarizabilities, and underline large vibrational contributions to the polarizability in materials with largely delocalized electrons.
