Patent ID: 7951892

Claim:
A method of making a doped poly(aryl)silane, comprising: a) mixing a doped silane compound of the formula A a H b+2 (DR x ) m (optionally further including a silane compound of the formula A c H d+2 R 1 e ) with a catalyst of the formula R 4 w R 5 y MX z (or an immobilized derivative thereof) to form a doped poly(aryl)silane of the formula H-[A a H b (DR x ) m ] q -[(A c hl d R 1 e ) n ] p —H, where each instance of A is independently Si or Ge; D is B, P, As or Sb; each instance of R is independently H, -A f H f+1 R 2 f or -A f H f R 2 f — (where R 2 is H, halogen, aryl or substituted aryl), alkyl, alkylene, aralkyl, substituted aralkyl, halogen, aryl, arylene or substituted aryl, and when an instance of x=2, the two R groups may form a ring together with D; q is at least 1, but q≧2 when p=0; each of the q instances of a is independently at least 1; each of the q instances of b is independently an integer of from 1 to 2a; each of the q instances of m is an integer of from 1 to a; each of the q*m instances of x is independently 1 or 2; each instance of R 1 is independently H, -A f H f+1 R 2 f , halogen, aryl or substituted aryl; each of the p instances of n is independently at least 1; each of the p*n instances of c is independently an integer of at least 1; each of the p*n instances of d is independently an integer of from c to 2c; each of the p*n instances of e is independently an integer of from 0 to c; and the sum of the p instances of n*c≧4 when q=1; M is a metal selected from the group consisting of Ti, Zr and Hf, w=1 or 2, y=1, 2 or 3, z=0, 1 or 2, 3 (x+y+z)≦8, each of the w instances of R 4 is independently a substituted or non-substituted cyclopentadienyl, indenyl, fluorenyl, siloxyl, germoxyl, hydrocarbyl, hydrocarbyloxy, hydrocarbylamino, or hydrocarbylsulfido ligand; each of the y instances of R 5 is independently a substituted or non-substituted hydrocarbyl, hydrocarbyloxy, hydrocarbylamino, hydrocarbylsulfido, silyl, (per)alkylsilyl, germyl, (per)alkylgermyl, hydride, phosphine, amine, sulfide, carbon monoxide, nitrile, or isonitrile ligand, and X is a halogen; and b) removing said metal from said doped poly(aryl)silane.
