Two new star-shaped A-π-D molecules with triazine as a core and an acceptor unit, thienylenevinylene as the π bridge, and tert-butyl-substituted triphenylamine (tTPA)- or carbazole (tCz) as the end group and donor units of TTVTPA and TTVCz were synthesized for their application as donor materials in solution processed bulk heterojunction organic solar cells (OSCs). The charge transfer was convergent from peripheral groups to the central core along the conjugated branches in these star-shaped molecules (SSMs). TTVTPA and TTVCz are soluble in common organic solvents. Excellent thermal stability was observed for TTVTPA and TTVCz. OSCs were fabricated by spin-coating a blend of each SSM with the fullerene derivatives (PC61BM or PC71BM) as a composite film-type photoactive layer. The PV properties of the TTVTPA/fullerene derivative based OSCs were considerably better than those of the TTVCz/fullerene derivative blend based OSCs. A power conversion efficiency of 2.48%, a short-circuit current density of 10.57 mA cm-2, an open-circuit voltage of 0.69 V, and a fill factor of 0.34 were observed for the OSC based on the active layer of TTVTPA/PC71BM (1:7, w/w).

Pi-conjugated organic molecules featuring the donor–bridge–acceptor (D–π–A) structure have been widely used in semiconducting materials owing to their rigid structure, good thermal stability, excellent charge transfer, and high emission efficiency. To investigate the effect of the D–π–A molecular structure on the photophysical properties, in this contribution, three star-shaped D–π–A isomers based on the 2,4,6-triphenyl-1,3,5-triazine, spirofluorene, and triphenylamine moieties, that is, p-TFTPA, mp-TFTPA, and m-TFTPA, were synthesized by elaborately engineering the interconnecting position in the building-block units. The optophysical properties of these compounds were systematically explored by experiments and theory calculations. Definitively, changing the interconnecting position in these molecules played a significant role in the degree of π conjugation, which resulted in tunable emission colors from deep blue to green. Moreover, these isomers were employed as emissive dopants in organic light-emitting diodes. The highest external quantum efficiency of 2.3 % and current efficiency of 6.2 cd A?1 were achieved by using the p-TFTPA based device. This research demonstrates a feasible way to realize blue emitters by engineering D–π–A conjugation.
