Abstract

Preparation of the acetylenic analogues of triphenylmethane dyes (triphenylmethane dye ethynylogues. TPMDE) and studies on their colour andconstitution are described. Derivatives of pyrylium dyes and merocyanine dyes have been obtained in the preparative studies of TPMDE. The absorption and emission spectral properties of bis(phenylethynyl) benzenes and the related anthracene derivatives are summarized, together with some donor-acceptor tolan derivatives; for the preparation of these, a novel one-stage conversion of the C=C bond to the C=C acetylenic bond was found to be useful.
