Embodiment 1
[0021] Concrete synthetic steps are as follows:
[0022] Weigh raw materials according to the following weight percentage:
[0023] TCNQ lipid derivatives are selected from 2,5-dipropionic acid methyl ester-7,7,8,8-tetracyanoquinone dimethane: (TCNQ(CH 2 CH 2 COOCH 3 ) 2 ): 0.5%
[0024] NaI: 0.5%
[0025] CuI: 0.5%
[0026] Acetonitrile: 98.5%
[0027] At 85°C, dissolve methyl 2,5-dipropionate-7,7,8,8-tetracyanoquinodimethane in acetonitrile, and pass nitrogen protection;
[0028] Add NaI, stir to make NaI fully dissolve, add cuprous iodide (CuI), and react for 2 hours;
[0029] After the reaction is complete, the resulting crude product is filtered out, purified, and dried to obtain 2,5-dipropylmethyl ester-7,7,8,8-tetracyanoquinone dimethane lipid derivative electron transfer Complex: Cu(TCNQ(CH 2 CH 2 COOCH 3 ) 2 )
