NOVELTY - A p-type conducting polymer comprises n-repeating units.    USE - The polymer is useful for preparing article that is conductor or semiconductor, where the article is selected from organic solar cell, flexible electronics, logic and memory devices, printing electronic circuits, organic light-emitting diodes, actuators, electrochromism, supercapacitors, chemical sensors and biosensors, flexible transparent displays, and electromagnetic shielding, preferably the article is a solar cell and a flexible solar cell (all claimed).    ADVANTAGE - Conjugated polymer compositions are provided to be used as semiconductors in low-cost solar cell and flexible electronics that are easily synthesized and purified on large scales.    DETAILED DESCRIPTION - A p-type conducting polymer comprises n-repeating units of poly formula (I).    n=greater than 1;    R1 and R2=independently selected from 1-18C alkyl, 1-18C alkoxy, Cy1, Cy1-(1-18C alkyl)-, Ar1, and Ar1-(1-18C alkyl)-, where R1 and R2 are optionally covalently bonded to form a 3- to 17-membered cycloalkyl or, together with 1-3 heteroatoms, comprise a 4- to 17-membered heterocyclo alkyl;    R3 and R4=independently selected from 1-18C alkyl, 1-18C alkoxy, Cy1, Cy1-(1-18C alkyl)-, Ar1, and Ar1-(1-18C alkyl)-; where R3 and R4 are optionally covalently bonded to form a 3- to 17-membered cycloalkyl or, together with 1-3 heteroatoms, comprise a 4- to 17-membered heterocyclo alkyl; where each of R5 and R6 is independently selected from 1-18C alkyl, 1-18C alkoxy, 1-18C monoalkylamino, 1-18C dialkylamino, Cy1, Cy1-(1-18C alkyl)-, Ar1, Ar1-(1-18C alkyl)-, -(1-18C alkyl)-(C=O)R7, -(1-18C alkyl)-(C=O)OR7, -(1-18C alkyl)-S(O)mR7, -(C=O)R7, -(C=O)OR7, and -S(O)mR7;    Ar1=selected from phenyl and heteroaryl, and independently substituted with 0, 1, 2, 3, or 4 groups independently selected from 1-18C alkyl, 1-18C alkoxy, 1-18C alkylamino, and 1-18C dialkylamino;    Cy1=selected from 3-18C cycloalkyl and 2-17C heterocycloalkyl, and substituted with 0, 1, 2, 3, or 4 groups independently selected from 1-18C alkyl, 1-18C alkoxy, 1-18C alkylamino, and 1-18C dialkylamino; and    R7=selected from hydrogen, 1-18C alkyl, 1-18C alkoxy, 1-18C monoalkylamino, and 1-18C dialkylamino.    An INDEPENDENT CLAIM is included for an article of manufacture comprising the polymer.
