We have succeeded in the development of 2, 4, 6-triethyl-1, 3, 5-di(alkylamino) benzene dynamic combinatorial library having affinity to hemin by utilizing aldehyde/amine-imine equilibrium reaction between 2, 4, 6-triethyl-1, 3, 5-benzenetricarbaldehyde(1) scaffold and amines. Increased products in the presence of hemin had higher affinity with hemin than not increased products. Porphyrin having four aldehyde precursors as a scaffold was synthesized. Equilibrium reaction between scaffold 1 and boomerang-form diamines converged to a cage-type supramolecule mainly.
