Abstract: The use of polyselenophenes as non-linear optical materials is novel. The use of a polyselenophene(s)containing units of formula (I) and/or (II) as non-linear optical material is claimed: -A-(III) -A=A-(IV) -A=A-A=A-(V) -A(H)-A=A-(VI)X and Y = H, provided that not both are H, 1-22C alkyl,alkoxy(alkyl) or (thio)acyl(oxy), 5-8C cycloalkyl or heterocycle,6-18C aryl, all optionally substituted with 1-22C alkyl,alkoxy(alkyl) or (thio)acyl, NO2, or NHR1;R1 = H, 1-22C alkyl, alkoxy(alkyl) or (thio)acyl;X and Y can also form a ring containing N, O, S and/or P and optionally substituted by Z;Z = as X and Y or two form a group of formulae (III)-(VI); and A = C, N and/or P and, if C, carries either a H atom or is substituted as for X and Y. Independent claims are included for the use of a composition comprising a polyselenophene(s) as above and a further polymer(s)as non-linear optical material, a non-linear optical material comprising the above polyselenophene(s) or composition and the use of a film or sheet containing the above polyselenophene(s) or composition as a non-linear optical material POLYMERS - Polyselenophene contains units of formula(VII) and/or (VIII) and unit (II) is from groups of formulae(IIa)-(IIg) (claimed): n and k = 1-10;l = 1-3000; and R2 = CHR12 or CH2R.The polyselenophene is prepared by reacting (i)2,5-dihaloselenophenes or 2,5-ditriflateselenophenes with a trialkyl tin-substituted selenophene derivative with units of formula (II), in the presence of Pd(O) or Pd(II) complexes; or(ii) 2,5-bis(trialkyl tin)selenophene with a halogen- or trialkyltin-substituted selenophene derivative, with units of formula(II), in the presence of Pd(O) or Pd(II) complexes.
