Due to the unique electronic structure, azulene-containing polycyclic aromatic hydrocarbons attract significant attention toward tuning the chemical and electronic properties of benzenoid carbocyclic systems. Here, we report the synthesis and properties of two types of azulene fused, seco-hexabenzocoronene-based nanographenes. The X-ray crystallographic analysis indicated their nonplanar structures with highly torsional periphery in the solid structures. The typical narrow highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO–LUMO) energy gaps, long-wavelength absorption, and anti-Kasha emissions were investigated by experimental and computational studies. Interestingly, these nanographenes exhibited a pronounced photothermal effect.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
