A Diaminoterephthalate-C-60 Dyad: A New Material for Optoelectronic Applications

Diaminoterephthalate was used for the first time as a chromophore in a dyad with [60]fullerene. The synthesis was accomplished from the benzyl methyl diester by hydrogenolytic cleavage of the benzyl group, re-esterification with a benzyl alcohol with protected formyl function, deprotection of the latter and final 1,3-dipolar cycloaddition with C-60 and sarcosine via the azomethine ylide.
