80% With trichlorophosphate; In chloroform; at 0 - 90℃; for 8h; General procedure: DMF (0.4 ml)was added into a dried round-bottom flask and thesystem was cooled to 0 C. A solution of CHCl3 (3 ml) containing1ae1i (5 mmol) was then added following the addition of redistilled POCl3 (0.45 mL). Then, the solution mixture was heated to 90 C for 8 h. After most of the CHCl3 was removed the residue waspoured into ice water and the pH was then adjusted to 7-8 using NaHCO3, the water layer was extracted with CH2Cl2 and organiclayer was washed with water several times before being dried with Mg2SO4, after CH2Cl2 was removed, the crude product was purifiedby column chromatography using ethyl acetate/petroleum ether(1:10, V/V) as an eluent, and finally a primrose solid was obtainedfor 2a-2i in 62e81% yields.

A solution of CHCl3 (3 ml) containing 1a-1m(5 mmol) was then added following the addition of redistilled POCl3 (0.45 mL).Then, the solution mixture was heated to 90 C for 8 h. After most of the CHCl3 was removed the residue was poured into ice water and the pH was then adjusted to 7-8 using NaHCO3, the water layer was extracted with CH2Cl2 and organic layer was washed with water several times before being dried with Mg2SO4, after CH2Cl2 was removed, the crude product was purified by column chromatography using ethyl acetate/petroleum ether (1:10, V/V) as an eluent, and finally a primrose solid was obtained for 2a-2m in 62-81% yields.
36.1% Step 2. 9-Benzyl-9H-carbazole-3-carbaldehyde; A 50-mL 3-necked round-bottomed flask was charged with N,N-dimethylformamide (400 mg, 5.42 mmol, 2.80 equiv, 99%). To this, POCl3 (700 mg, 4.56 mmol, 2.40 equiv, 99%) was added drop wise with stirring at 0 C. and allowed to stir at room temperature for 1 hour. To this mixture was added 9-benzyl-9H-carbazole (500 mg, 1.93 mmol, 1.00 equiv, 99%) in small portions at 45 C. over 5 minutes. Then, the temperature was raised to 95 C. in an oil bath and allowed to stir for 18 hours. The progress was monitored by TLC (EtOAc:PE=1:4). Upon completion, the reaction mixture was cooled down to room temperature and quenched with water (20 mL). The resulting mixture was allowed to stir for an additional 4 hours at room temperature. The solids were collected by filtration and dried to afford 9-benzyl-9H-carbazole-3-carbaldehyde as green solid (200 mg, 36.1%). LCMS: [M+H]+: 286
2.64 g With trichlorophosphate; at 80℃; for 3h;Cooling with ice; In a 100mL three-necked flask equipped with a magnetic stirrer, 3g (12mmol) of the prepared N-benzylcarbazole dissolved in 10mL DMF was added. The mixture was subjected to an ice bath. 4mL POCl3 was slowly added dropwise. After addition of POCl3, the solution was cooled at room temperature giving a pale yellow solution. The solution was heated at 50C for 20min then temperature was raised to 80C. The solution turned dark red. the reaction was continued 3h forming a precipitate. The reaction was stopped. The mixture was filtered and dried to give 2.64g of N-benzylcarbazol-3-aldehyde as a pale yellow solid.
5.41 g With trichlorophosphate; at 0 - 20℃; for 17h;Reflux; A solution of CHCl3 (25 mL) containing 9-benzyl-9H-carbazole (6.43 g, 25 mmol) and DMF(1.86 mL) was cooled to 0C. POC13 (2.3 mL) was slowly added at 0C and the solution was allowedto stir to room temperature for one hour. Then, the solution mixture was refluxed for 16 h. Duringreaction, a yellow precipitate formed. After cooling, the solution was poured into ice water. Theyellow solid was filtered off, washed with ether and pentane, and dried under vacuum. The crudeproduct was recrystallized in ethanol, and cooled at -30C to end the precipitation (5.41 g, 76%yield).

40% Step 3. 9H-Carbazole-3-carbaldehyde; A 250-mL round-bottomed flask was charged with a solution of AlCl3 (9.26 g, 69.45 mmol, 20.00 equiv, 99%) in 1,2-dichloroethane (150 mL). To this was added <strong>[54117-37-2]9-benzyl-9H-carbazole-3-carbaldehyde</strong> (1 g, 3.47 mmol, 1.00 equiv, 99%) in several batches at room temperature over 5 minutes. The resulting mixture was stirred for 2 hours at room temperature. The reaction was then quenched by the addition of H2O/ice (100 mL). The solids were filtered out. The resulting solution was extracted with DCM (3×100 mL) and the combined organic layers were concentrated on a rotary evaporator to give a residue that was purified by silica gel column chromatography eluted with PE:EtOAc (10:1) to afford 9H-carbazole-3-carbaldehyde as green solid (270 mg, 40%).

YieldReaction ConditionsOperation in experiment
84% With chloro-trimethyl-silane; In N,N-dimethyl-formamide; at 100℃; for 48h; The antenna ligand for NC-11 was synthesized in a pressure tube containing 4,4'- dimethyl-2,2'-bipyridine (2g, 0.0108 mol) and 9-benzyl- H-carbazole-3-carbaldehyde (6.19g, 0.0217mol) and 0.065mol of trimethylchlorosilane, and magnetic stirrer bar in 70ml DMF. The reaction temperature was raised to 100C and allowed to run for 48 hours with continuous stirring. During the course of the reaction, the color of the reaction mixture changed to yellow and turned orange on cooling and release of pressure from the tube. The solvent was removed using rotary evaporator, and the orange product was recovered by addition of water and filtration under vacuum to furnish the ancillary ligand in 84% yield. Scheme 3 shows a schematic of the synthesis of the antenna ligand for NC-11.

YieldReaction ConditionsOperation in experiment
80% With pyridine; In ethanol; at 80℃; for 4h; The above-prepared compound A34 and 1.1 equivalents of rhodamine 3-acetic acid were dissolved in ethanol, one equivalent of pyridine was added, and the reaction was carried out at 80 C. for 4 hours. After the reaction was completed, the reaction mixture was cooled to room temperature to precipitate a yellow solid, which was suction-filtered and the filter cake was diluted. After washing with hydrochloric acid, washing with water, infrared drying, and then recrystallization with ethanol gave a yellow solid with a yield of 80%.

YieldReaction ConditionsOperation in experiment
87% With sodium acetate; acetic acid; at 110℃; for 4h; General procedure: A mixture of the appropriate aldehydes (2a-2m, 0.1 mmol), the rhodanine-3-acetic acid (0.1 mmol), and NaOAc (0.3 mmol) in acetic acid (6 mL) heated to 110 C for 4h. Then, it was cooled to room temperature and poured into water. The product was then filtered through the suction pump, washed with water/EtOH (1/1, v/v) to remove the excess acetic acid and recrystallized from EtOH and finally a yellow solid was obtained for 3a-3m in66-91% yields.
