物理学与化学交叉——有机分子固体与聚合物的物理问题

简略地回顾了有机固体领域中物理学与化学的交叉问题，从孤子、极化子、分数电荷理论到有机材料的光电应用，物理学与化学是紧密结合并且是互相促进的，交叉也会带来分歧，但科学的争论可提出更多，更深入的问题，更加促进学科的发展。

INTERACTION OF PHYSICS AND CHEMISTRY ——PHYSICAL ASPECTS OF ORGANIC MOLECULAR SOLIDS AND POLYMERS

We briefly review some physical aspects of organic solids, which manifest the cross linking of physics and chemistry. Form the theories of solitons, polarons and fractional charge to opto electronics applications, of organic materials we find that there exists a strong interaction between physics and chemistry, which is mutually beneficial. This interdisciplinary cross linking could also bring about controversy. However, scientific debates pose more and further questions to be answered, which is essential for the advancement of science.
