Our research explores the synthesis of oxygenated hydrocarbon products with linear chains up to C 17 using an organotitanium photocatalytic system. This breakthrough enables the direct conversion of atmospheric carbon into complex, long-chain organic molecules, advancing green chemistry and renewable energy goals. The visible-light-activated organotitanium complexes exhibit self-organizing behavior, forming autocatalytic reaction networks. These networks drive three self-sustaining cycles, where reaction products catalyze subsequent reactions, showcasing an innovative approach to sustainable molecular assembly.
