dc.description.abstract |
Derivatives of benzene chromium tricarbonyl, (116-arene)chromiumtricarbonyl,
and a molybdenum complex, trans-bis(I,2-bis(diphenylphosphinoethane)bis(P-isocyanoaniline)
molybdenum (0), were polymerized to form rigid organometallic polymer
systems are reported. The resulting polymers were characterized systematically. The
organochromium monomers were prepared by reacting the arene with chromium
hexacarbonyl in refluxing dibutyl ether/tetrahydrofuran under inert conditions. There
were several steps in the synthesis of the organomolybdenum monomer. p-Phenylenediamine
was converted to p-isocyanoaniline in the presence of potassium
hydroxide. Trans-bis(1,2-bis(diphenylphosphinoethane)bis(dinitrogen) molybdenum (0)
was prepared by reducing molybdenum (V) chloride with a sodium/mercury amalgam in
the presence of dinitrogen gas and bis(diphenylphosphinoethane) in tertrahydrofuran.
Trans-bis(l ,2-bis(diphenylphosphinoethane)bis(dinitrogen) molybdenum (0) and pisocyanoaniline
were reacted in tetrahydrofuran to prepare the organomolybdenum
monomer,trans-bis(l ,2-bis(diphenylphosphinoethane)bis(p-isocyanoaniline) molybdenum
(0). The syntheses and characterizations of model compounds and related organic
polymers were attempted. Analogous model compounds and organic polymers were
synthesized from isocyanates and acid chlorides in either dimethylacetamide or
tetrahydrofuran. A series of organic polymers was synthesized via low temperature
solution polycondensation from reacting diisocyanates and acid chlorides with the
organometallic monomers in solution. An attempt to set up a gel permeation
chromatography lab to determine the molecular weight of the polymers was unsuccessful.
It is believed that the compounds formed from m-phenylenediamine, except for the
monomer, have not been previously reported. The molybdenum polymers have not been
reported. The organometallic polymers reduce the amount of hydrogen bonding of the
polymers and increases the solubility of the polymers. |
