    naphthalenediimides alternately fused on the five-membered rings in pyracylene units, through one-step crossing-coupling-cyclization cascade reaction, are reported. This fusion pattern allows to a planar backbone and enhances the aromatic character of pyracylene. Electrochemical experiments reveal that the electronic communication occurs between the adjacent NDI redox centers, resulting in multiple
    据报道,通过一步交联-环化-级联反应,两种含有萘二甲酰亚胺的新型化合物交替地稠合在pyr基单元的五元环上。该熔融图案允许形成平坦的骨架,并增强了ac并苯的芳族特性。电化学实验表明,相邻NDI氧化还原中心之间发生电子通信,从而导致多个不同的还原态。π扩展的共轭导致带隙减小,而LUMO水平未受影响。

    The synthesis of multiply substituted acenes is still a relevant research problem, considering their applications and future potential. Here we present an elegant synthetic protocol to afford tetra-peri-substituted naphthalene and tetracene from their tetrahalo derivatives by a Pd(0)-catalyzed C-C cross-coupling method in a single step. The newly synthesized tetracenes were characterized by NMR, HRMS
    考虑到其应用和未来潜力,多取代并苯的合成仍然是一个相关的研究问题。在这里,我们提出了一种优雅的合成方案,通过 Pd(0) 催化的 CC 交叉偶联方法一步即可从四卤代衍生物中获得四邻位取代的萘和并四苯。新合成的并四苯通过核磁共振、高分辨质谱、紫外可见分光光度法和单晶 X 射线衍射 (SCXRD) 进行了表征。此外,这里还报道了硫属苯基取代对双苯手性光学性质影响的首次系统计算研究。

    affording 1,7-dibromonaphthalene upon treatment with trifluoromethanesulfonic acid (halogen dance reaction). For 1,4,5,8-tetrabromonaphthalene, stepwise 1,2-rearrangements proceeded successively to furnish 1,3,5,7-tetrabromonaphthalene. Density functional theory calculations suggest that this reaction is initiated by ipso-protonation, with a subsequent 1,2-rearrangement occurring via the bromonium

    The narrowest armchair graphene nanoribbon (AGNR) with five carbons across the width of the GNR (5-AGNR) was synthesized on Au(111) surfaces via sequential dehalogenation processes in a mild condition by using 1,4,5,8-tetrabromonaphthalene as the molecular precursor. Gold-organic hybrids were observed by using high-resolution scanning tunneling microscopy and considered as intermediate states upon AGNR formation. Scanning tunneling spectroscopy reveals an unexpectedly large band gap of Delta = 2.8 +/- 0.1 eV on Au(111) surface which can be interpreted by the hybridization of the surface states and the molecular states of the 5-AGNR.
