AB - Disclosed is a polymer (I), wherein one of X1 and X2 is Se and the other one is S or Se, R1 and R2 are independently of each other identical or different groups selected from H, halogen, -CN, -NC, -NCO, - NCS, -OCN, -SCN, -C(=O)NR0R00, -C(=O)X0, -C(=O)R0, -NH2, -NR0R0, -SH, -SR0, -SO3H, -SO2R0, -OH, -NO2, -CF3, -SF5, P-Sp-, optionally substituted silyl, or carbyl or hydrocarbyl with 1 to 40 C atoms which is/are optionally substituted and optionally comprise one or more hetero atoms, P is a polymerizable group, Sp is a spacer group or a single bond, X0 is halogen, R0 and R00 are independently of each other H or an optionally substituted aliph. or arom. hydrocarbon group having 1 to 20 C atoms, Ar is in case of multiple occurrence independently of one another -CY1=CY2, acetylene or mono- or polynuclear aryl or heteroraryl which is optionally substituted, Y1 and Y2 are independently of each other H, F, Cl or CN, m is 0-4, and n is an integer > 10. The invention relates to polymers comprising fused selenophene rings, to their use as semiconductors or charge transport materials in optical, electrooptical or electronic devices, and to optical, electrooptical or electronic devices comprising them. In the examples of the invention, first 2,5-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)selenopheno[3,2-b]thiophene was prepd. and (0.25 g, 0.56 mmol) of it was polymd. with (0.43 g, 0.56 mol) of 5,5'-dibromo-4,4'-dihexadecyl-2,2'-bithiophene by using Pd2[dba]3, tris-(tert-butyl) phosphine tetrafluoroborate and K2CO3 as catalysts, after pptn. and purifn. 0.37 g, 82 % of poly[5,5'-(4,4'-dihexadecyl-[2,2']bithiophene)-co-(selenopheno[3,2-b]thiophene)] was obtained.
