Syntheses of α,ω-di-1-anthrylpolyenes have been carried out by the Wittig reaction for information on the role of aromatic terminalgroups on the electronic spectral regularity of α,ω-diarylpolyenes. The reaction of phosphoranes derived from 1-anthrylmethyl-, 3-(l-anthryl)propenyl-, and 5-(1-anthryl)-pentadienyltriphenylphosphonium bromides with 1-formylanthracene, 3-(1-anthyrl)propenal, 5-(1-anthryl)pentadienal
