Compared to the parent acene, boron incorporation shifts the transport-dominating molecular orbital from a centrally localized distribution to a delocalized configuration across the orthogonal molecular backbone.

2019年2月20日 · In this article, we introduce an effective approach toward the on-surface formation of large acenes via photodecarbonylation of α-bisdiketone precursors on a coinage metal surface under UHV...

2014年6月19日 · Acenes represent a series of molecules with intriguing physical and chemical properties for applications in organic electronics. Nevertheless, the stability and solubility issues associated with longer acenes are two major obstacles for their applications. In this Perspective, we summarize the major design principles for stabilizing acenes.

2023年5月4日 · Here, we report the synthesis of polyacene by using a methodology, distinct from conventional methods, grounded on organic and/or surface chemistry. The proposed strategy involves two steps:...

2018年5月23日 · Turn it up to eleven: Larger acenes ranging from heptacene to undecacene have been obtained by on-surface synthesis. The structure of the generated acenes has been visualized by high-resolution non-contact atomic force microscopy.

2019年3月1日 · Photochemistry based on acenes and their derivatives is one of the emerging research areas in the field of polycyclic aromatic hydrocarbons (PAHs). However, due to the increased reactivity of larger acenes towards light and singlet oxygen, it is difficult to precisely control their photochemical reactions.

2013年1月1日 · Acenes are polycyclic aromatic hydrocarbons that consist of linearly fused benzene rings. The smaller members of the acene series are well-known organic compounds. For example, benzene 1 was discovered by Michael Faraday in 1825, and the next highest homologue, naphthalene 2, was isolated in 1819 from coal tar.

2017年5月14日 · Acenes are fascinating polyaromatic compounds that combine impressive semiconductor properties with an open-shell character by varying their molecular sizes. However, the increasing chemical instabilities related to their biradicaloid structures pose a great challenge for synthetic chemistry.

2024年7月30日 · Acenes, the group of polycyclic aromatic hydrocarbons (PAHs) with linearly fused benzene rings, possess distinctive electronic properties with potential applicability in material science. Hexacene was the largest acene obtained and characterized in the last century, followed by heptacene in 2006.

2016年11月16日 · The improved optoelectronic properties predicted for acenes larger than pentacene have prompted the development of new strategies for the synthesis of stabilized higher acenes with the aim of obtaining improved functional materials for application in the field of molecular electronics.
