Organic polymers which are "hydroxyphenyl-substituted" and "ether-substituted" polypyrroles ("PP") linked through N-adjacent C atoms, are disclosed which are compactable, extrudable and are also electrical conductors. When such PPs are prepared by electrochemical deposition with an appropriate electrolyte, they are also soluble in commonly available solvents, provided at least one of the 3- or 4-positions of the pyrrole nucleus is substituted with a substituent having either a hydroxyphenyl, or an ether structure. By choice of the hydroxyphenyl and/or ether substituent on one of the substitutable positions (3- or 4-) of the pyrrole nucleus, or both, the PP may be tailored for use either as a semiconductor having a conductivity in the range from about 10.sup.-5 to about 10.sup.-2 S/cm, or a relatively good conductor having a conductivity in the range from about 10.sup.-2 to about 10.sup.2 S/cm. A method is disclosed for preparing an ether-substituted pyrrole comprising reacting a non-Michael acceptor selected from the group consisting of esters, ketones and nitriles having vinylene carbon atoms, with tosylmethylisocyanide, in the presence of a solvent, so as to form a hydroxyphenyl-substituted or an ether-substituted pyrrole directly without substituting the pyrrole ring in the 2- and 5-positions.
本发明涉及一种有机聚合物,其为“羟基苯基取代”和“醚取代”聚
吡咯(“PP”),通过N-相邻的C原子连接,具有可压缩性,可挤出性,并且也是电导体。当使用适当的电解质通过电
化学沉积制备这样的PP时,它们也可溶于常见的溶剂,只要
吡咯环的3-或4-位置中的至少一个被取代为具有羟基苯基或醚结构的取代基。通过在
吡咯环的可取代位置(3-或4-)中选择羟基苯基和/或醚取代基中的一个或两个,可以将PP量身定制为半导体,其电导率在约10^-5到约10^-2 S/cm范围内,或者是相对较好的导体,其电导率在约10^-2到约10^2 S/cm范围内。本发明还公开了一种制备醚取代
吡咯的方法,包括在溶剂存在下,将选自酯、酮和腈的非Michael受体,具有
乙烯基碳原子的物质与对
甲苯磺酰甲基
异氰酸酯反应,以直接形成羟基苯基取代或醚取代
吡咯,而不在2-和5-位置上取代
吡咯环。
