We report a precise measurement of $^{216}\rm Po$ half-life using the PandaX-4T liquid xenon time projection chamber (TPC). $^{220}\rm Rn $, emanating from a $^{228}\rm Th $ calibration source, is injected to the detector and undergoes successive $α$ decays, first to $^{216}\rm …

Abstract Hydrocarbon belts have drawn great attention because of their unique structures and tantalizing properties. Although a few belts and heteroatom‐doped analogs have been synthesized, belt molecules containing non‐hexagonal rings remain rare. Herein we report the construction and application of unprecedented zigzag‐type …

Abstract Described in this paper are the synthesis and structure of novel and edge‐functionalized zigzag hydrocarbon belts. A stepwise “fjord‐stitching” strategy featuring repetitive intramolecular acylation reactions of a resorcin[4]arene derivative as the key steps afforded a biscarbonyl‐functionalized octahydrobelt[8]arene product. Facile ketone reduction …

Abstract Oxime condensation as well as template‐directed synthesis based on radical‐pairing interactions were used in the synthesis of an octacationic [2]catenane in 20 % yield. The [2]catenane consists of two identical mechanically interlocked tetracationic macrocyclic components. Each of the ring components contains …

Abstract Spin–spin interactions between two identical aromatic radicals have been studied extensively and utilized to establish supramolecular recognition. Here we report that spin-pairing interactions could also take place between two different π-electron radicals, namely a bipyridinium radical cation (BPY+•) and a naphthalene-1,8:4,5-bis(dicarboximide) …
