Abstract

The synthesis and physical properties of four series of novel fluorene push-pull compounds (4-7) of the D-π-A type with intramolecular charge transfer (from 1, 3-and 1, 2-dithiole and 1, 3-selenathiole donor (D) moieties) are described. The nature of the heteroatom (S or Se) in the donor fragment has no effect on the maxima of intramolecular absorption bands (λICT), whereas a change of position of the heteroatoms in the dithiole moiety from 1, 3 to 1, 2 ...
