    • note
    • [18] instead of performing chromatographic separation, analytical samples were isolated simply by precipitation and rinsing with pentane or methanol, followed by sublimation (yields: 30-60%). The anthracene derivative 15 does not withstand chromatographic purification, thus isolation can be only achieved by precipitation and sublimation.

    • The polymeric material spontaneously precipitated upon cooling of the reaction mixture is only partially soluble in THF, chloroform and dichloromethane. The soluble part was characterized by GPC and NMR. The insoluble fraction was only characterized by solid state NMR.

    • note
    • Probably the substitution at the 2 and 6 positions of the pyridine ring is causing formation of bent structures (helicate and/or random coiled) in which side-chain interactions are disrupting ring coplanarity with the consequent breakage of conjugation.
