PREPARATION AND SOME PROPERTIES OF POLYTHIA[n]FERROCENOPHANES

Abstract
Polythiaferrocenophanes, 5, and 8–12, were prepared from 1,1′-ferrocenedithiol. Of these compounds, 1,4,7-trithia[7]ferrocenophane 8 showed an abnormal bathochromic shift in the electronic spectrum, and a downfield shift of the bridge-head carbons and an upfield shift of the other cyclopentadienyl carbons in the 13C-NMR spectrum. Compounds 9–12 also showed complexing affinity to silver ion according to the size of polythia-macrocycles.
