A phase‐separated template prepared from a mixed monolayer of fluorinated long‐chain s‐triazine derivatives and comb copolymers containing s‐triazine rings was morphologically controlled by DNA adsorption. The adsorbed morphology of DNA was formed through a morphological transition process at the air/water interface rather than by maintaining the shape of the phase‐separated template. Dot‐like domains, circular domains, centrally protruding domains, network morphologies, and even co‐continuous surface morphologies of DNA were obtained. The phase‐separated monolayer used as a template depends on the mixed ratio of the fluorocarbon and hydrocarbon copolymer components, the copolymerization ratio of the hydrocarbon copolymers, and the chain length of the fluorinated long‐chain s‐triazine derivative, and various morphological transitions occur. The DNA introduced into the sub‐phase was selectively adsorbed onto the s‐triazine ring‐containing comb copolymer, and the adsorbed DNA assembly exhibited a morphological transition based on concerted interactions. Furthermore, by utilizing a fluorescent probe molecule, evidence of DNA morphogenesis itself was supported by its emission/quenching behavior.Highlights Morphological control of the DNA assembly was attained. Immobilization of DNA assemblies on phase‐separated templates was achieved. Preparation of patterned templates was realized by copolymers a fluorinated derivative. Adsorption of DNA to the diamino‐s‐triazine ring was achieved by hydrogen bonding. A rearrangement of the DNA assemblies on the template was achieved.

“…Recently, it has been reported that DNA can be adsorbed on mixed monolayers of copolymers composed of 2vinyl-4,6-diamino-1,3,5-triazine (VDAT):octadecyl acrylate (OA)/ non-amphiphilic fluorinated derivatives. [25] Various patterns resulting from the phase separation of these compounds have also been documented [26,27] (Figure 1(b)).…”

It has achieved the preparation of quasi‐deoxyribonucleic acid (DNA) origami using the techniques of organized molecular films. After the adsorption of DNA from the subphase onto a Langmuir monolayer of polymers containing diamino‐s‐triazine rings, the monolayer collapses owing to high surface pressure, resulting in the formation of a three‐dimensional folded structure of DNA. A homopolymer featuring a diamino‐s‐triazine ring and a copolymer containing 20 % long alkyl chains are used to form the Langmuir monolayer. A‐T base pairs of salmon testis‐derived DNA from the subphase are hydrogen‐bonded and adsorbed onto each Langmuir monolayer. Following the collapse of the Langmuir monolayer, the film height almost doubles, indicating the formation of a bilayer structure consisting of a bioadsorbed polymer monolayer, especially evident in copolymer‐collapsed films. During this period, the bioconjugated bilayer structure adopts a mesoscopic linear morphology within the plane. In this quasi‐DNA origami structure, the chirality in the DNA molecule is maintained, as evidenced by the circular dichroism (CD) spectra displaying a positive Cotton effect. These results correspond to the proposal of a new DNA morphology control technology.
