We have extended our functionalization strategy for pentacene to the higher acenes hexacene and heptacene. Provided a large enough alkyne substituent is used, these large aromatic rods are both stable and soluble and can be characterized spectroscopically as well as by single-crystal X-ray diffraction.
我们已将并五苯的功能化策略扩展到更高级的并苯六苯和七苯。如果使用足够大的炔烃取代基,这些大芳烃棒既稳定又可溶,并且可以通过光谱和单晶 X 射线衍射进行表征。

A new and stable nitroso-nitro-enamine reagent, providing a nitrile oxide 1,3-dipole, has been treated with dipolarophiles in the course of 1,3-dipolar cycloaddition reactions to give a large number of novel isoxazolyl-pyrroline derivatives. Surprisingly, instead of the expected 2-isoxazolyl-dihydropyrrole cycloadducts, dihydropyrrol-3-one oximes were isolated as the main products in most cases. The

[structure: see text] We report the synthesis of a series of crystalline acenedithiophenes with up to seven linearly fusedrings and silylethynyl substituents. These functional groups are designed to both improve solubility and enhance cofacial interactions in the solid. We discuss the crystal packing of these materials, as well as their physical properties such as oxidation potential, UV-vis absorption
