<p>A method of making a compound of the formula shown below is disclosed:
wherein Z is Se or S; Y is NH or O; X is O or S and W and W' are independently selected from the group consisting of hydrogen, -C=ONH 2 , -C=ONHR', -C=ONR'R', -C‰¡N, and R' is C 1-6 alkyl and the resultant monomer compounds. The method includes contacting a 3,4-disubstituted thiophene or selenophene or disubstituted thiophene or selenophene derivatives with a carbonyl or thiocarbonyl containing compound selected from the group consisting of ureas, thioureas, carbonate esters, thionocarbonates, thiocarbonate esters, or orthocarbonates. The monomer compounds are suitable for forming polymers for use in a wide range of electronic applications.</p> |
