“…These results indicate the unimolecular nature of the resulting amine-and hexanoyl-terminated digital oligomers/ polymers. The corresponding 1 H and 13 C NMR spectra are shown in Figures S47, S52, S56, S60, S64, and S68. Similarly, the unimolecular nature of the hydroxyl-and carboxylterminated digital oligomers/polymers was confirmed using GPC (Figures S41, S44 As shown in Scheme 2, the backbone of the digital O24mer contained three sources of ester bonds, originating from two ring-opening reactions (δ-VLs and anhydrides) and one P-3CR coupling reaction.…”

The preparation of digital polymers with high information storage density, efficient information encoding, and easy information decoding characteristics is challenging. Using small cyclic compounds, such as δ-valerolactones, β-amino acid Nthiocarboxyanhydrides, and anhydrides, as monomers, we developed iterative growth methods to prepare novel types of digital polymers. The use of small cyclic monomers provides significant advantages for iterative growth methods and the resulting digital polymers. First, small cyclic monomers with a large variety of side group structures can be easily obtained, which significantly expands the monomer alphabet and increases the information storage density of the digital polymers produced (reaching 0.023 bit/Da). Second, small cyclic monomers contain self-protected reactive groups, eliminating the need for protective groups or orthogonal reactive−group pairs. These cyclic monomers also exhibit high nucleophilic ring-opening reactivity under mild reaction conditions, facilitating the use of new efficient iterative growth methods to encode information. Third, the simple ring structure of cyclic monomers results in digital polymers with simple backbone structures that contain only two types of functional groups: esters and amides. As a result, the encoded information can be easily and reliably decoded by using tandem mass spectrometry sequencing, selectively cleaving ester bonds with lower dissociation energies. This study demonstrates that small cyclic monomer codes are promising for the development of efficient iterative growth methods to prepare high-storage-density digital polymers with easy and reliable readability.

“Click” chemistry, featuring high selectivity, efficiency, and modularity, has been regarded as a powerful tool to construct and engineer macromolecular materials with complex and disordered structures. In this work, we reported our first effort to use the thiol-Michael “click” chemistry to tune the energy structure and light harvesting behavior of melanin-like polymers by “clicking” mercaptotetrazole (MT) building blocks into the complicated polydopamine (PDA) networks, successfully acquiring a series of melanin-like nanoparticles with boosted light absorption and photothermal effect. A comprehensive characterization by density functional theory (DFT) stimulation, spectral analysis, cyclic voltammetry, and transient absorption demonstrated the energy bandgap reduction and light harvesting enhancement of those MT-doped PDA samples. The resulting polymers also exhibited excellent photothermal effect, which could be applied in efficient electric energy generation through photothermoelectric conversion and solar desalination application. This study provided new opportunities to regulate the functions of a complex bioinspired macromolecule system through “click” chemistries.

Inspired by life's interaction networks, ongoing efforts are to increase complexity and responsiveness of multicomponent interactions in the system for sensing, programmable control, or information processing. Although exquisite preparation of single uniform-morphology nanomaterials has been extremely explored, the potential value of facile and one-pot preparation of multimorphology nanomaterials has been seriously ignored. Here, multimorphological silver nanomaterials (M-AgN) prepared by one pot can form interaction networks with various analytes, which can be successfully realized from multimode and multianalyte colorimetric sensing to molecular information technology (logic computing and security). The interaction of M-AgN with multianalytes not only induces multisignal responses (including color, absorbance, and wavelength shift) for sensing metal ions (Cr 3+ , Hg 2+ , and Ni 2+ ) but also can controllably reshape its four morphologies (nanodots, nanoparticles, nanorods, and nanotriangles). By abstracting binary relationships between analytes and response signals, multicoding parallel logic operations (including simple logic gates and cascaded circuits) can be performed. In addition, taking advantage of natural concealment and molecular response characteristics of M-AgN nanosystems can also realize molecular information encoding, encryption, and hiding. This research not only promotes the construction and application of multinano interaction systems based on multimorphology and multicomponent nanoset but also provides a new imagination for the integration of sensing, logic, and informatization.
