A series of novel Y-shaped dyes bearing the D–π–A–π–D fragment comprising central 2-alkoxy-or 2-alkylthio-substituted pyrimidine core and terminal 2-(1-methyl-1H-pyrrol-2-yl)vinyl moieties have been synthesized and studied as potential materials for the organic electronics. The obtained compounds demonstrated an efficient absorption at ~410 nm with the high molar absorption coefficient (29790–40620 dm3 mol?1 cm?1) and fluorescence emission at ~480 nm (ΦF ~ 7.5–8.6%). Thin films of 2-ethyloxy- or 2-ethylthiopyrimidines exhibited the red-shifted photoluminescence (~600 nm).

A new molecule, 5,5′-bis(4,6-bis((E)-4-(octyloxy)styryl)pyrimidin-2-yl)-2,2′-bithiophene (OSPB), was designed and synthesized. It contains two D-π-A-π-D (donor-π-acceptor-π-donor) segments with an alkoxy group D and a pyrimidine moiety A, and these two segments are connected through a bithiophene moiety to shape a two-dimensional (2D) multibranched conjugated system. The molecule showed high thermal stability. It demonstrated good solubility in THF with an emission maximum at 470 nm, and excimer emission appeared in poor solvents such as aqueous media showing an obvious red-shift. A two-photon excited fluorescence (TPEF) test revealed that the maximal two-photon absorption (2PA) cross-section of the molecule was 1352 GM, which is comparable with the reported bipyrimidine-based multibranched compounds with a stronger donor. Theoretical calculation suggested that the molecule showed good coplanarity made up by two conjugated segments with a small dihedral angle. The charge transport ability of OSPB was preliminarily studied using an organic thin-film transistor (OTFT) device via a low-cost solution processing technique, and the results demonstrated that it was a p-type semiconductor.
