Abstract
AbstractThienyltriazine (TT) is a C3h symmetric system consisting of an acceptor core and donor arms. Here we report the design, synthesis and characterization of a series of aryl (naphthalene, NP; benzodithiophene, BDTP; BODIPY, BDPY; hexyl thiophene, HT; imidazole, IMZ; indole, IN) functionalized thienyltriazine containing star molecules (TTNP, TTBDTP, TTBDPY, TTHT, TTIMZ and TTIN). The electronic properties of these compounds in the solution were studied by ultraviolet‐visible absorption and emission spectroscopies, and cyclic voltammetric studies. The star molecule (SM) consisting of thienyltriazine and BDPY unit (TTBDPY) shows the most red‐shifted absorption and emission wavelength indicative of its most extended conjugation. The results of the experimental observations reveal that changing the nature of the peripheral aryl unit helps to efficiently tune the optical properties of the resulting system.
