1. An arylene oligomer comprising as polymerized units a first monomer having two cyclopentadienone moieties and a second monomer having two or more alkyne moieties, wherein at least one alkyne moiety is directly bonded to a silicon atom, and wherein the second monomer is chosen from formula (5) and formula (6)wherein a is an integer from 0 to 4; b is 2 or 3; c is 2 or 3; each R6 is independently chosen from H, Si(R8)3, C1-10 alkyl, C1-10 alkoxy, C7-15 aralkyl, C6-10 aryl, and substituted C6-10 aryl; each R7 is independently chosen from H, C1-10 alkyl, C1-10 alkoxy, C7-15 aralkyl, C6-10 aryl, and substituted C6-10 aryl, each R8 is independently chosen from H, halogen, hydroxyl, C1-10 alkyl, C1-10 alkoxy, C7-15 aralkyl, C7-15 aralkoxy, C6-10 aryl, C6-20 aryloxy, and substituted C6-10 aryl; and Ar3 is C6-10 carbocyclic aryl; provided that at least one R6 is Si(R8)3. |
