    using the resulting aldehyde‚ along with 2‚4-dimethylpyrole‚ a BODIPY dye was obtained [36]. To facilitate intersystem crossing‚ the 2- and 6- positions of the boradiazaindacene ring system were iodinated with an iodic acid-iodine mixture [37]. Bromination at the same positions was performed via N-bromosuccinamide (NBS) [38]. 8-Palmitoyl-1‚ 3‚ 5‚ 7-tetramethyl-2‚ 6 diiodo-4-bora‚ 3a‚ 4a-diaza-s-indacene was obtained by the iodination of 8-palmitoyl-1‚ 3‚ 5‚

    Experimental Synthesis of Bupropion – A round bottom flask (RBF) containing m-chloropropiophenone (1.0 g‚ 5.9 mmol) dissolved in 5.0 mL dichloromethane (DCM) with 0.25 mL of 1.0 M Br2 in DCM was briefly warmed to initiate the bromination reaction. Afterwards‚ the RBF was placed in and ice-water bath and 1.0 M Br2 in DCM (6.0 mL‚ 6.25 mmol) was added dropwise while stirring. DCM was removed from the reaction by rotary evaporation. Next‚ tert-butylamine (5.0 mL‚ 47.6 mmol) and 5.0 mL of N-methylpyrrolidinone
