Boosting self-assembly diversity in the solid-state by chiral/non-chiral ZnII-porphyrin crystallization
A chiral ZnII porphyrin derivative 1 and its achiral analogue 2 were studied in the solid state. Considering the rich molecular recognition of designed metalloporphyrins 1 and 2 and their tendency to crystallize, they were recrystal- lized from two solvent mixtures (CH2Cl2/CH3OH and CH2Cl2/ hexane)....

| Sumario: | A chiral ZnII porphyrin derivative 1 and its achiral analogue 2 were studied in the solid state. Considering the rich molecular recognition of designed metalloporphyrins 1 and 2 and their tendency to crystallize, they were recrystal- lized from two solvent mixtures (CH2Cl2/CH3OH and CH2Cl2/ hexane). As a result, four different crystalline arrangements (1 a,b and 2 a,b, from 0D to 2D) were obtained. Solid-state studies were performed on all the species to analyze the role played by chirality, solvent mixtures, and surfaces (mica and HOPG) in the supramolecular arrangements. By means of combinations of solvents and substrates a variety of mi- crosized species was obtained, from vesicles to flower- shaped arrays, including geometrical microcrystals. Overall, the results emphasize the environmental susceptibility of metalloporphyrins and how this feature must be taken into account in their design. |
