NEW MATERIALS WITH NOVEL TOPOLOGIES - SYNTHESIS AND CHARACTERIZATION OF TELOMERS AND POLYMERS WITH RIBBON TOPOLOGY

The five, seven and nine ring analogues of thianthrene have been made as model compounds for ribbon polymers based on the structural motif s hown below. [GRAPHICS] The smaller molecules are soluble and readily c haracterised but the nine ring model compound and polymers based on th is structural motif are insoluble and intractable. Analaogues of the m odel compounds and polymers which carry decyl substituents are soluble up to species having about seventy rings.
