Abstract

Abstract In the quest for fast fluors for use in waveshifting polystyrene fibers, symmetrical oligofurans were investigated. Furan moieties were coupled by means of the Ullmann Reaction or by palladium-catalyzed unsym-metrical coupling; the latter gave higher yields. While the benzoxazole-terminated quater-and quinquifurans we prepared were both stable and fast, exhibiting a green fluorescence and decay times of about 2.4 nsec, they were ...
