Disclosed herein are embodiments of aryl compounds and polymers thereof that are made using methods that do not require harsh conditions or expensive reagents. The methods disclosed herein utilize precursor compounds that can be polymerized to form polycyclic aromatic hydrocarbons and polymers, such as carbon-based polymers like nanostructures (e.g., graphene or graphene-like nanoribbons).

alkynes has been well studied. A method is reported that utilizes the β-silyl effect to override this typically observed anti selectivity and provides halogenation products that result from syn addition. The reaction involves the addition of iodinemonochloride to trialkylsilyl-substituted alkynes to produce tetrasubstituted (Z)-dihaloalkenes in good to excellent yields and with excellent regio- and diastereoselectivity
developed for installing stable polyradicals into polycyclic π-systems, as illustrated by the formation of an air-stable, high-spin carbon-based diradical with a new ferromagnetic coupling motif of diazapyrene. The structure of the diradical was confirmed by X-ray diffraction, while the magnetic measurements provided unambiguous evidence for the high-spin ground state and a long spin relaxation process.
