This article examines the chemical, evolutionary, and technological foundations of its expansion, focusing on plasticity, codon architecture, and amino acid selection. The triplet codon structure reflects an evolutionary compromise between metabolic cost and information capacity, while proteins - the essential catalytic polymers - are built from α-L-amino acids derived from L-alanine. Introducing non-triplet codons or non-α amino acids would demand new metabolic pathways to supply precursors and energy for synthetic life. Current methods for incorporating noncanonical amino acids - stop codon suppression, sense codon reassignment, and quadruplet recoding - are transient and inefficient, consistent with the “ambiguous intermediate” model. Achieving stable expansion requires redesigning tRNA identity sets, improving ribosomal fidelity, rewiring metabolism, and potentially creating new foldamer scaffolds. Orthogonal translation systems and codon box deconstruction have become key tools, while permanent codon reassignment and engineered orthogonal systems mark the likely future. Core technologies include genome-scale codon swapping, directed evolution, cellular compartmentalization, and metabolic integration. Framed by evolutionary models such as Wong's coevolution theory, the WesthoffGrosjean model, and the Alanine World hypothesis, genetic code expansion emerges as a radical extension of life's chemical vocabulary.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the underpinning of these relatively complex interactions is still a challenging foray, advancement in density functional theory and high-level calculations with wave-function-based quantum mechanical approaches have led to reliable interpretations of these weak interactions, with sufficient accuracy, to provide meaningful insights on their physical origins in molecular binding and chemical transformations. Such an in-depth understanding of electronic structure and reactivity offers possibilities for judicious engineering of these complex intra/intermolecular interactions to achieve enzyme-like optimum efficacy. In this study, we therefore focus on applications that demonstrate the advantages of rational manipulation of noncovalent interactions in molecular and supramolecular organocatalytic frameworks, pertaining to chiral catalysis, electron-donor acceptor events in photo-redox catalysis, or transformations within confined spaces of self-assembled capsules and cages. We emphasize on how quantum chemical data analysis provides reasonable indications of catalyst performance. We also highlight the ongoing challenges in computing reaction outcomes and discuss remedial approaches. We believe this overview would provide guiding principles for the successful designing of organo-catalysts using noncovalent weak interactions.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While modeling studies have focused on the catalyst for at least two decades, recently the electrolyte–electrode interface has attracted significant attention, especially metal cations. In this Perspective, we propose simple rules to predict the extent of cation effects on <math></math> and water reduction depending on the transition metal catalyst, which we later extend to the case of alkali cation-induced surface dissolution. First, we highlight the difficulty of activating <math></math> and the crucial boost that cations provide for late transition metals. Then we re-interpret state-of-the-art results in terms of a unique descriptor, i.e., cation-induced electrostatic potential. Finally, we suggest a possible qualitative explanation for cation effects in cathodic dissolution and mention strategies to overcome cation-induced salt formation. The final Outlook lists directions that the modeling field should follow, i.e., either simplicity (Computational Cation Electrode) or complexity (Multiscale models), showing the potential of simulations toward the understanding of novel electrochemical processes (i.e., <math></math> in organic cations).","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500749","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
