ROUTES TOWARDS 3-DIMENSIONAL FULLY CONJUGATED CONDUCTING POLYMERS .1.PREPARATION OF THE KIT OF MONOMERS

We have prepared and characterized several triethienylbenzenes. These compounds an used as reticulation points in poly(3-n-octylthiophene). It was necessary to study the reactivity of the reticulation points wi th regard to 3-n-octylthiophene. That is the reason why we have prepar ed copolymers starting from very high percentages of deuterated reticu lation points (> 10%) and monitored their reactivities following the e volution of the =C-D band in the infra-red spectra of the copolymers. The copolymers thus obtained contain from 10% to 30% of reticulation p oints. They swell in apolar solvents whereas the poly(reticulation poi nt) (100% of reticulation points) does not swell. A low molar doping l evel (FeCl3.6H(2)O, <9%) leads to a non-negligible conductivity (0.1 t o 0.2 S cm(-1)) of these copolymers. In the same conditions, the poly( reticulation point) cannot be doped and thus remains insulating.
