Embodiment 1a
[0045] Example 1a: One 114mg of (R,R)cyclohexanediamine and 222mg of tetraphenylvinylaldehyde were placed in a 25mL sealed tube, and 2mL of glacial acetic acid and 6mL of 1,4-dioxane were added. Freeze and thaw three times with liquid nitrogen, seal the tube, and let stand at 120°C for 72h. The solid was taken out, extracted with tetrahydrofuran, ethyl acetate, and ethanol by Soxhlet for 24 h each, and dried in vacuum at 100° C. for 10 h to obtain 280 mg of R-CCOF-1 with a yield of 95%.
[0046] The infrared spectrum of R-CCOF-1 is as follows figure 1 shown.
[0047] The PXRD pattern of R-CCOF-1 is as follows figure 2 shown.
Embodiment 1b
[0048] Example 1b: One 114mg of (R,R)cyclohexanediamine and 244mg of tetraphenylvinylaldehyde were placed in a 25mL sealed tube, and 2.3mL of glacial acetic acid and 6mL of tetrahydrofuran were added. Freeze and thaw three times with liquid nitrogen, seal the tube, and let stand at 120°C for 68h. The solid was taken out, extracted by Soxhlet with tetrahydrofuran, ethyl acetate, and acetone for 24 hours each, and dried in vacuum at 120° C. for 8 hours to obtain R-CCOF-1.
Embodiment 1c
[0049] Example 1c: A 114 mg of (R, R) cyclohexanediamine and 200 mg of tetraphenyl aldehyde were placed in a 25 mL sealed tube, and 1.7 mL of glacial acetic acid and 6 mL of toluene were added. Freeze and thaw three times with liquid nitrogen, seal the tube, and let stand at 110°C for 80h. The solid was taken out, extracted by Soxhlet with tetrahydrofuran, acetone, and ethanol for 24 hours each, and dried in vacuum at 80° C. for 18 hours to obtain R-CCOF-1.
