Silane Compound For Use In The Synthesis Of Semiconducting Polymers With Perpendicularly Arranged Cores And Method Of Synthesizing Said Compound

View page
US Patent:
51439930, Sep 1, 1992
Filed:
Aug 5, 1991
Appl. No.:
7/740319
Inventors:
James M. Tour - Columbia SC
Ruilian Wu - Columbia SC
Jeffry S. Schumm - Columbia SC
Assignee:
University of South Carolina - Columbia SC
International Classification:
C08G 7706
US Classification:
528 15
Abstract:
The stereochemical structure necessary for preparation of perpendicularly arranged cores is provided by a compound of the formula ##STR1## wherein X is a reactive group through which polymeric subunits can be bonded to the compound. In particular, X is advantageously Br. This compound can be synthesized by the reaction of tetrakis(3'-trimethylsilyl-2'-propynyl)silane with zirconocene dichloride and n-butyllithium and adding sulfur monochloride to the reaction product. This produces an adduct in which X is SiMe. sub. 3. This adduct may be converted to the bromo compound by reaction with bromine. The tetrakis(3'-trimethylsilyl-2'-propynyl)silane may be prepared by forming a magnesium Grignard reagent from 3-bromo-1-trimethylsilylpropyne and reacting the Grignard reagent with silicon tetrachloride.
