For preparation of [(Co(NCS))(TPT)] crystalline sponges, the methanol solution of Co(NCS) was added into the TPT solution in 1,2-dichlorobenzene/methanol. After 7 days, the [(Co(NCS))(TPT)] would form and can be isolated by filtration.
For preparation of [(ZnI)(TPT)] crystalline sponges, the methanol solution of ZnI was added onto the top of TPT in nitrobenzene solution. After 7 days, the [(ZnI)(TPT)] would form and can be isolated by filtration.
Once the feedstocks were mixed, crystalline sponges would be produced via self-assembling processes, forming the thermodynamically stable organized network structures.
