Abstract: PROBLEM TO BE SOLVED: To obtain an optically stable thiophene compd. or its compsn. showing high nonlinearity and having fast relaxing time by incorporating a specified polythiophene. SOLUTION: The material contains at least one kind of polythiophene having structural units expressed by formula I and formula II. In formulae I and II, X, Y are straight-chain or branched-chains alkyl groups having 1 to 22 carbon atoms or straight-chain of branched-chain alkoxyl groups having 1 to 22 carbon atoms, or X and Y with atoms bonded to these may form a cyclic structure containing carbon atoms. The cyclic structure contains not only carbon atoms but nitrogen (N) heteroatoms, oxygen (O) heteroatoms, sulfur (S) heteroatoms or (P) phosphorus heteroatoms or two or more kinds of these heteroatoms. Moreover, the cyclic structure may have substltuents Z on the position of carbon atoms, nitrogen atoms or phosphorus atoms, and each Z independently represents the same groups as defined as X and Y.

Abstract: Non-linear optical (NLO) materials - comprise one or more polythiophenes (P) containing repeat units of formula (I) and (II) :X, Y = 1-22C alkyl, 1-22C alkoxy, 1-22C alkyloxyalkyl, 1-22C acyl(oxy), 1-22C thioacyl(oxy), 5-8C cycloalkyl, 6-18C aryl or 5-8C heterocycle, any of which may be substituted with one or more 1-22C alkyl, 1-22C alkoxy, 1-22C alkyloxyalkyl or 1-22C (thio)acyl ; NO2 or NHR ; or X and Y may form a ring containing at least one N, O, S and/or P heteroatom, in which at least one of the ring atoms may be substituted with a group Z ; R = H, 1-22C alkyl, 1-22C alkoxy, 1-22C alkyloxyalkyl or 1-22C (thio)acyl ; Z = X or two Z groups can combine to form a group of formula (III)-(VI) ; and A = C, N or P, or a combination of at least two of these atoms, with the provision that any C atom is bonded to a H atom or substituted in the same way as X. Also claimed are (i) non-linear optical materials comprising a formulation (Q) of at least one polymer (P) and at least one other polymer and (ii) non-linear optical materials containing (P) or comprising (Q).
