We have conducted a detailed electron-microscopic investigation of the structure and morphology of α-hexathienyl (α-6T), a hexameric homologue of polythiophene that shows great promise as a thin-film-transistor material. In ordinary films for devic

Building upon the previous results on silicon-based homopolymers, the authors have now synthesized and characterized copolymers of these novel materials. The copolymers poly(di-n-butylsilylene-co-di-n- pentylsilylene) (PB-co-PS) and poly(di-n-pentyls

The polysilylenes exhibit complex solid-state structures and electronic properties. In this report the solid-state conformational structures of symmetrically substituted poly(di-n-alkylsilylenes) are described. Comparisons between the different struc

PEEK crystallized at temperatures between 300 and 320°C was studied. No support was found for suggested changes in crystal structure, growth face, growth direction or gross spherulitic morphology. In addition to narrow, fibrous lamellae, evidence wa

Although poly(aryl ether ether ketone) (PEEK) and poly(ether imide) (PEI) blends are compatible in the melt, phase separation occurs during crystallization of the PEEK component. At high temperatures (∼320°C) compact PEEK spherulites are observed

We have obtained and studied the first single crystals of the important silicon-backbone polymer, poly(dimethyl silylene) (PDMS), by dissolution in α-chloronaphthalene at 251°C and growth at 238°C. The crystals consist of molecularly folded, rhomb

It is shown that the structure and morphology of syndiotactic polypropylene depend very sensitively and in a unique wanner on the temperature of crystallization. Moreover, as the temperature of crystallization is lowered, edge-on lamellae of isotacti
