31% | With triethylamine; at 20 - 105℃; for 48h; | Fe2(SO4)3.xH2O (0.19 g, 0.47 mmol) and 4,4'-terphenyldicarboxylic acid (H2TPDC) (0.15 g, 0.47 mmol) were placed in a 50 mL round bottom flask, to which 15 mL of N,N-dimethylformamide (DMF), 15 mL of pyridine, and 130 muL neat triethylamine (TEA) were added. The heterogeneous reaction mixture was capped and allowed to stir at room temperature for 24 h. A 6 mL aliquot of the stirring heterogeneous reaction solution and 4 mL of pyridine were added to a glass scintillation vial (20 mL capacity). The vial was capped and heated to 105 C. (5 C./min) for 24 h and cooled (0.5 C./min) to room temperature to give an orange/red homogeneous solution. After 4 days at room temperature, the orange product crystallized as plates of IRMOP-53 on the vial walls (31% yield based on H2TPDC). Crystals of IRMOP-53 were isolated, washed with 3×10 mL of pyridine, and 1×10 mL of cyclohexane. Anal.

200 mg | To a stirred solution of 3-((6-aminohexyl)(tert-butoxycarbonyl)amino)-7-(tert-butoxycarbonyl amino)-2,8-dimethyl-5-phenylphenazin-5-ium chloride (450 mg, 0.69 mmol) in 5 mL of DMF were added EDC.HC1 (i8i mg, 0.942 mmol), and HOBt (i27 mg, 0.942 mmol), and the mixture stirred for 5 mm. To this were added i,4-di(4-carboxyphenyl)benzene (100 mg, 0.314 mmol) and DIPEA (0.21 mL, i.25 mmol). The reaction mixture was stirred at RT for i2 h. After completion of reaction, the reaction mixture was diluted with ice-cold water and extracted with EtOAc. The organic layer was washed with brine (4x10 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford a crude product, which was purified by column chromatography (neutral alumina) to afford the desired product (200 mg). | |
