Ll. Miller et al., AN OLIGOTHIOPHENE CATION-RADICAL THAT FORMS PI-STACKS - A MODEL FOR POLARON AGGREGATION IN CONDUCTING POLYMERS, Advanced materials, 7(6), 1995, pp. 547-548
A new class of functional units for preparing charge transfer salts, b
ased on pi-stacks of a conducting oligomer in analogy to the well-know
n stacks of TTF units, is reported and provides a connection between C
T salts and conducting polymers. The synthesis of the new water-solubl
e thiophene oligomer is presented and it is suggested that pi-stacks m
ay be present in some oxidized polythiophenes and similar polymers.
