Bottom Line: A feasible and effective self-assembly method to synthesize different scale coordination polymers in highly dilute solution (from nanocrystals to microcrystals and to bulk crystals) without any blocking agent has been described.The growth of crystalline particles was controlled by removing the particles at different reaction times to interrupt the growth at the desired size.The nano and microscale particles show better catalytic conversions and selectivities in the hydroxylation of phenols than the bulk crystals.

ABSTRACT
A feasible and effective self-assembly method to synthesize different scale coordination polymers in highly dilute solution (from nanocrystals to microcrystals and to bulk crystals) without any blocking agent has been described. The growth of crystalline particles was controlled by removing the particles at different reaction times to interrupt the growth at the desired size. The nano and microscale particles show better catalytic conversions and selectivities in the hydroxylation of phenols than the bulk crystals.

Figure 5: TGA and DTG curves of the as-synthesized MCPs-1.

Mentions: The relative thermal stabilities of the as-synthesized crystalline MCPs-1 were studied using thermogravimetric analysis. Thermogravimetric analysis of products showed the loss of one lattice water and one coordinated water per formula unit in the temperature range 80-100°C, and the loss of the C2O42- between 175°C and 205°C. The curve between 205°C and 260°C corresponds to the volatilized phen molecule (Figure 5). It may be concluded that the as-synthesized MCPs-1 is stable between room temperature and 80°C.
