Abstract

A new π‐conjugated polymer consisting of isothianaphthene and bis(dodecyloxy)‐p‐phenylene units has been prepared by Pd‐catalyzed organometallic polycondensation. X‐ray diffraction analysis indicates that the polymer assumes an interdigitation‐type self‐assembled packing structure in the solid state and aligns on the surface of a platinum plate, with the dodecyloxy side chain oriented toward the surface of the platinum plate. The polymer undergoes facile electrochemical doping as well as chemical doping with iodine and NOBF~4~. BF‐doped polymer is also considered to assume an interdigitation‐type packing structure in the solid state. Electrical conductivities of the chemically doped polymer are also reported.

## Abstract A series of π‐conjugated alternating copolymers consisting of Th‐ITN‐Th and __p__‐C~6~H~2~(OR)~2~ units were synthesized. XRD indicated that the copolymers assume an interdigitation packing mode, and UV‐Vis spectra revealed a strong tendency for self‐assembly. Upon molecular assembly of
