Architecture of Matter: From Alchemy to Molecular Design

The article analyzes a fundamental paradigm shift in chemistry: the transition from studying the composition of substances to designing their molecular architecture. The author indicates that this breakthrough allowed the molecule to be treated as a structure capable of being constructed, rather than merely discovered in nature. A key moment was the debunking of vitalism through Wöhler's synthesis of urea, which proved that the nature of a substance depends on its structure rather than its origin. The text explains how the development of structural theory and the understanding of carbon's tetravalence transformed organic chemistry into a form of engineering. Modern synthesis is presented as an architectural process in which retrosynthesis allows for the precise planning of complex molecular objects, turning the laboratory into a place for the creation of new forms of matter.
