Abstract We have created a selective macroscopic self‐assembly process by using polymer gels modified with complementary DNA oligonucleotides or nucleobases. The hydrogels modified with complementary DNA oligonucleotides adhered to each other by simple contact. The organogels modified with complementary nucleobases selectively formed macroscopic assemblies by agitation in nonpolar organic solvents. The adhesion strength of each gel was estimated semi‐quantitatively by stress–strain measurements. We achieved direct adhesion between macroscopic materials both in water and in organic media, based on complementary hydrogen bonds.
