STABILITY OF THE ISOMERS OF DIHYDROTHIAMINE
THE JOURNAL OF VITAMINOLOGY, 1964 Stabilities of dilute solutions of n- and Ψ-TH2 in an alkaline solution and degradation by sulfite were investigated.1. The stabilities of two isomers upon heating or standing at room temperature showed no difference; they were both unstable in a weakly acidic medium but relatively stable in a neutral medium.

Advanced Science, EarlyView.A single‐molecule cascade supramolecular system comprising L/D‐FPy, CB[8], and SC4AD serves as an efficient light‐harvesting platform. It facilitates cascade energy transfer and chiral transfer to acceptor dyes. Co‐assembly with a PVA matrix produces a multicolor solid film that exhibits enhanced luminescence dissymmetry factors (glum), enabling ...
