Acenes, extended pi systems composed of linearly annulated benzene rings, are an important class of organic materials. The members of the acene series beyond hexacene are highly reactive and hence were difficult to study or are even unknown. The major focus of the research project is the photochemical generation of unknown higher acenes under the conditions of matrix isolation and their characterization by spectroscopic techniques. The research is expected to answer fundamental questions concerning the electronic ground state and the poly radical character of the higher acenes. The investigation of thermal and photochemical reactions of the unstable acenes under cryogenic and ambient conditions provides an insight into the chemical properties of these highly reactive pi systems.

苯乙烯是一类重要的有机材料，它是由线性环苯环组成的扩展体系。正己烯以外的正己烯系列的成员反应性很强，因此很难研究，甚至是未知的。本研究的主要重点是在基质分离条件下光化学生成未知高级芳烃，并利用光谱技术对其进行表征。该研究有望回答有关电子基态和高等烃的多自由基性质的基本问题。研究不稳定烃在低温和环境条件下的热化学和光化学反应，有助于深入了解这些高活性pi体系的化学性质。
