Preferred Definitions:    R1 and/or R2=electron-donating group chosen from optionally substituted ferrocene-containing group and phenyl having amine in para-position and/or ortho-position, preferably phenyl having amine in para-position and/or ortho position, and R1 is preferably electron-donating group, more preferably group (G1), or group having pi-bond, preferably group (G), and R2 is preferably phenyl having amine in para-position;    R3=single bond;    R4=group having pi-bond, preferably group (G);    R5=double bond;    z=0;    R6=group having pi-bond;    group (G)=thiophene, phenylene, phenylene vinylene, fluoroarene, phenylene ethynylene, vinylene, thynylene, thiazole, benzodi thiophene, thieno thiophene, di-thienothiophene, cyclopenta dithiophene, triphenylamine, pyrrole, 2,1,3-benzothiadiazole, thieno pyrazine and 1H-benzo(de)anthracene;and    group (G1)=phenyl having amine in para-position and/or ortho-position, phenyl having alkoxy in ortho-position and/or para-position, amino, monosubstituted amino, disubstituted amino, optionally substituted ferrocene-containing group, optionally substituted pyrrole-containing group, optionally substituted carbazole-containing group or optionally substituted thiophene-containing group.    EXAMPLE - Tris (dibenzylidene acetone)dipalladium (in mg) (13.3), 4-((triisopropyl silyl)ethynyl)aniline (141) and 2,7-dibromo-9,9-dioctyl fluorene (284) were mixed. Sodium t-butoxide (162), toluene (0.6 ml) and tri(t-butyl)phosphine (22 mu l) were added and heated at 60 degrees C for 24 hours. Water and dichloromethane were added, and aromatic polyamine condensed product having number average molecular weight of 18100 and weight average molecular weight of 110000 was obtained. The obtained compound (50) was dissolved in tetrahydrofuran (10 ml), and tetrabutyl ammonium fluoride solution was added. A conjugated polymer compound having number average molecular weight of 13500 and weight average molecular weight of 55700 was produced.
