Method for making porphyrin covalent organic framework-based interface
A porphyrine organic framework (“POF”) material is introduced with a one-pot method for photothermal material fabrication. The POF material may be deposited on a support scaffold by reacting a pyrrole by acid-catalyzed dehydration forming a plurality of porphyrin-based covalent organic frameworks particles on the support scaffold.
1. A method of fabricating a photothermal material comprising:
providing, in an acidic solution, a porous support scaffold having pores of at least 10 nm average diameter to a reaction vessel;
adding a pyrrole to the reaction vessel; and
reacting the pyrrole with a terepthalaldehyde, added to the reaction vessel after providing of the porous support scaffold, by acid-catalyzed dehydration forming a plurality of porphyrin-based covalent organic frameworks particles on the porous support scaffold, the plurality of porphyrin-based covalent organic frameworks particles cover 20-50% of a surface of the porous support scaffold.
2. The method of claim 1 , wherein the pyrrole and the terepthalaldehyde are mixed in a 1:1 ratio for reacting.
3. The method of claim 2 , further comprising adding terepthalaldehyde acid as a catalyzer.
4. The method of claim 2 , wherein the pyrrole is present in a nitrobenzene solvent prior to mixing with the terepthalaldehyde.
5. The method of claim 1 , wherein the reacting is at temperature of 50-150° C.
6. The method of claim 1 , wherein reacting is for a period of 3-72 hours.
7. The method of claim 6 , wherein the period is for 6-12 hours.
8. The method of claim 1 , further comprising washing the particles and support scaffold.
9. The method of claim 1 , further comprising, after reacting, drying the plurality of porphyrin-based covalent organic frameworks particles on the support scaffold 50-150° C. for 1-4 hours.
10. The method of claim 1 , wherein the terepthalaldehyde comprises benzene-1,4, dialdehyde (BDA).
11. The method of claim 1 , wherein the porous support scaffold comprises a material selected from the group consisting of wood, AAO membrane, sponge, cork, ceramic, and fabric.
