To provide a water-soluble polythiophene used as an electrically conductive material, and its production method.
A polythiophene comprising at least one type of structural units selected from the group consisting of structural units represented by the formula (1), structural units represented by the formula (2), structural units represented by the formula (3), structural units represented by the formula (4), structural units represented by the formula (5) and structural units represented by the formula (6). The polythiophene is obtained by polymerizing at least one thiophene compound selected from the group consisting of a thiophene compound represented by the formula (15), a thiophene compound represented by the formula (16) and a thiophene compound represented by the formula (17) in water or an alcohol solvent in the presence of an oxidizing agent.

The perfluorosubstituted compounds of formula:
or
wherein a is a whole number or fraction thereof in the range of from about 4 to about 18; b is a whole number or fraction thereof in the range of from about 0 to about 30; c is a whole number or fraction thereof in the range of from about 1 to about 3; d is a whole number or fraction thereof in the range of from about 0 to about 3, d being less than or equal to c; e is a whole number or fraction thereof in the range of from about 1 to about 3, e being less than or equal to c; R is independently hydrogen or methyl whereby mixtures containing both groups may result; X+ is an exchangeable cation; and Z is a nucleophile-containing species containing at least one of oxygen and nitrogen, wherein the nitrogen is in the form of NR' wherein R' is independently hydrogen or methyl.
These perfluoro compounds can be used to increase the production of hydrocarbons from subterranean carbonate-containing formations.

The preferred oligomers of the present invention are polyureas, polycarbonates, polyesters or polyamides having a number average molecular weight of <10,000. These oligomers are water-soluble, have a rigid backbone, have recurring units coupled by carbonyl linking moieties which have anionic groups, display predominantly linear geomentry such that regular spacing between anionic groups exists in an aqueous medium, and are pharmaceutically-acceptable. The oligomers are useful for the treatment and/or diagnosis of AIDS and ARC.
