Abstract: PROBLEM TO BE SOLVED: To obtain a novel polyselenophene having a relatively high conductivity and good mechanical properties as well by reacting 2,5-dihaloselenophene or 2,5-ditriflate selenophene with a selenophene derivative which is substituted by bis(trialkyltin) groups on the carbon atoms adjacent to the selenium atom. SOLUTION: This is a polyselenophene comprising one or plural types of structural units of formulas I and/or II (wherein X and Y are each H, a 1-22C alkyl, a 1-22C alkoxyl, a 1-22C alkyloxyalkyl, a 1-22C acyl, a 1-22C thioacyl, a 1-22C thioacyloxy, a 5-8C cycloalkyl, a 6-18C aryl, a 5-8C heterocyclic group, NO2 , or NHR , R is H, a 1-22C alkyl, a 1-22C alkoxyl, a 1-22C alkyloxyalkyl, a 1-22C acyl, or a 1-22C thioacyl, and X and Y may be combined with each other to form a carbon-containing ring having a plurality of types of heteroatoms).

Abstract: PROBLEM TO BE SOLVED: To obtain an optically stable selenophene compd. which may be produced and processed to a thin film form by a simple process, has an excellent nonlinear characteristic and has a rapid relaxation time and optically high quality by using a nonlinear optical material contg. specific polyselenophene. SOLUTION: This nonlinear optical material contains the polyselenophene having the structural units of formula I or formula II or >=1 kind of the formula I or the formula II. In the forms, X and Y may be same or different and respectively independently denote hydrogen (in this case only either of X and Y is hydrogen), straight or branched 1-22C alkyl group, straight or branched 1-22C alkoxy group, etc. Or X and Y and the atom to which these are bonded may cojointly form a carbon-contg. ring having nitrogen (N), oxygen (O), sulfur (S) or phosphorus (P) hetero atom in addition to a carbon atom or >=2 kinds of these hetero atoms.

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.
