POLYMERIZATION OF METHYLACETYLENE IN HYDROGEN ZEOLITES

Acid zeolites as media for the alignment and packaging of included conjugated polymers were investigated with the goal of producing materials with enhanced nonlinear optical properties. Methylacetylene gas was absorbed onto acid forms of Mordenite, Omega, L, Y, Beta, ZSM-5, and SAPO-5 a room temperature. The resulting yellow to red-brown powders were characterized by mass uptake, powder XRD, TPD-TGA, C-13 CP/MAS NMR, H-1 MAS NMR, UV-vis, ESR, FTIR, heptane absorption, ammonia bleaching, and chemical extraction techniques. The data show that large, conjugated, oligomeric species are formed within the internal void spaces of the zeolites.
