Abstract:
A monmeric, oligomeric, or polymeric [3-(1,1-difluoroalkyl)thiophene] compound comprising one or more identical or different recurring units of formula Iâ€”[(Y)aâ€”(D)bâ€”(Z)c]â€”â€ƒâ€ƒI whereinD is a 3-(1,1-difluoroalkyl)thiophene group of formula II R1 is H, straight chain, branched or cyclic alkyl with 1 to 20 C-atoms, which is unsubstituted, mono- or partially-substituted by F, Cl, Br, I, â€”CN or â€”OH, wherein optionally one or more non-adjacent CH2 groups is replaced, in each case independently from one another, by â€”Oâ€”, â€”Sâ€”, â€”NHâ€”, â€”NR0â€”, â€”SiR0R00â€”, â€”COâ€”, â€”COOâ€”, â€”OCOâ€”, â€”OCOâ€”Oâ€”, â€”Sâ€”COâ€”, â€”COâ€”Sâ€”, â€”CH&boxH;CHâ€” or â€”Câ‰¡Câ€” in such a manner that O and/or S atoms are not linked directly to one another, or optionally substituted aryl or optionally substituted heteroaryl, R2 is H, F, straight chain, branched or cyclic alkyl with 1 to 20 C-atoms, which is unsubstituted, mono- or poly-substituted by F, Cl, Br, I, â€”CN or â€”OH, wherein optionally one or more non-adjacent CH2 groups is replaced, in each case independently from one another, by â€”Oâ€”, â€”Sâ€”, â€”NHâ€”, â€”NR0â€”, â€”SiR0R00â€”, â€”COâ€”, â€”COOâ€”, â€”OCOâ€”, â€”OCOâ€”Oâ€”, â€”COâ€”, â€”COâ€”Sâ€”, â€”CH&boxH;CHâ€” or â€”Câ‰¡Câ€” in such a manner that O and/or S atoms are not linked directly to one another, or optionally substituted aryl or optionally substituted heteroaryl, R0 and R00 are independently of each other H or alkyl with 1 to 12 C-atoms, Y and Z are independently of each other â€”CX1&boxH;CX2â€”, â€”Câ‰¡Câ€”, or optionally substituted arylene or heteroarylene, X1 and X2 are independently of each other H, F, Cl or CN, and a, b and c are independently of each other 0 or 1, with a+b+c>0, and wherein in at least one recurring unit b is 1, wherein if n and b both equal 1 and a and c both equal 0, then at least one of the terminal groups of the compound is not H.
