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.

并苯是由线性环状苯环组成的扩展π系统，是一类重要的有机材料。六苯以外的并苯系列成员具有​​高反应性，因此很难研究，甚至是未知的。该研究项目的主要重点是在基质分离条件下光化学生成未知的高级并苯并通过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级并苯的多自由基特征的基本问题。对低温和环境条件下不稳定并苯的热和光化学反应的研究提供了对这些高反应性 pi 系统的化学性质的深入了解。
