Reaction of a dithiol with B(OH) 3 and base in MeOH followed by reaction with xylylene dibromides proceeds selectively to give the corresponding ortho, mete or pare-cyclophanes in good yield (70-86 %). The syntheses of examples of all three types of benzenophanes are discussed. The molecular structu

The electronic structure of poiy(&xylylene) is of particular interest in the study of conducthrg Polymeric materials because it lies at the border between materials in which molecular cation states aredelocalized over several polymeric repeat units (e-g. polyethyiene [l] , polyacetylene [2,3] and po
## Abstract Polymer films with small Agโclusters and Agโnanocrystals were obtained by the cocondensation of Ag and chloroโ__p__โxylylene from the gaseous phase followed by lowโtemperature solidโstate polymerization. UVโVis spectroscopic data show that the annealing of films at ambient temperature a
