Synthesis of the meso-10-phenylanthracene-BODIPY dimer (n = 1), trimer (n = 2) and tetramer (n = 3). Reaction conditions: (Ia) PIFA, BF3·OEt2, DCM, −78 °C - r.t, 1 h. (Ib) anhydrous FeCl3, DCM, r.t., 25 min. The dimer was obtained using Ia and Ib. The trimer and tetramer were obtained using Ib. The S0-S1 transition dipole moments for the anthracene and BODIPY units are depicted as red, dashed arrows24.
