Cyclic oligothiophenes macrocycles

Fig. 20 a Structure of a cyclic a-conjugated oligothiophene macrocycle 38 at the liquid-HOPG interface, b STM image (15 x 12 nm ) of the ordering and 2D crystal of 38 adsorbed on graphite, c Calculated minimimi-energy conformation of an individual macrocycle.

In addition to linear ohgomers, cyclic a-conjugated macrocyclic oligothiophenes (Fig. 20, 38) have also been investigated. Spontaneous ordering was observed. The energy minimum does not correspond to a fully planar molecule but rather to a spiderlike conformation in which the alkyl side... [Pg.227]
