[0089] The preparation of monomer bis-osmopentyne M1: under nitrogen atmosphere, under magnetic stirring, the polyyne carbon chain organic compound L1 (1.50g, 3.55mmol), triphenylphosphine (9.32g, 35.5mmol) and triphenylphosphine (9.32g, 35.5mmol) and (Triphenylphosphine) osmium dichloride complex OsCl 2 (PPh 3 ) 3 (11.18 g, 10.65 mmol) was dissolved in 80 mL of dichloromethane. After reacting at room temperature for 6 hours, the reaction solution was concentrated to 15 mL, diethyl ether (200 mL) was added to precipitate the product, filtered, and the solid product was washed several times with diethyl ether (3×150 mL). The product was further separated and purified through a silica gel column (washing solution with dichloromethane / methanol=10:1), and 5.73 g of a tan solid product was obtained with a yield of 65%. The structural characterization data of monomer bis-osmopentyne M1 are as follows: 1 H NMR plus 1 H- 13 C HSQC (600.1MHz, CD 2 Cl 2 ): δ=13.09(s, 2H, C 7 H)...
