Check Digit Verification of cas no

The CAS Registry Mumber 1227195-24-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,1,9 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1227195-24:
145 % 10 = 5
So 1227195-24-5 is a valid CAS Registry Number.

Stoichiometry-controlled inversion of circularly polarized luminescence in co-assembly of chiral gelators with an achiral tetraphenylethylene derivative

Li, Pengyu,Lü, Baozhong,Han, Dongxue,Duan, Pengfei,Liu, Minghua,Yin, Meizhen

, p. 2194 - 2197 (2019)

A supramolecular circularly polarized luminescence (CPL) system was constructed based on the co-gelation of an achiral tetraphenylethylene derivative and chiral organic gelators of glutamic acid in chloroform. Adjusting the stoichiometric ratio was found to be an effective strategy for regulating the handedness of CPL.

PEG-induced synthesis of coordination-polymer isomers with tunable architectures and iodine capture

We designed and synthesized a new luminescent metal-organic framework (LMOF). LMOF-241 is highly porous and emits strong blue light with high efficiency. We demonstrate for the first time that very fast and extremely sensitive optical detection can be ach

Halogen-Bonded Organic Framework (XOF) Based on Iodonium-Bridged N???I+???N Interactions: A Type of Diphase Periodic Organic Network

Gong, Guanfei,Lv, Siheng,Han, Jixin,Xie, Fei,Li, Qian,Xia, Ning,Zeng, Wei,Chen, Yi,Wang, Lu,Wang, Jike,Chen, Shigui

, p. 14831 - 14835 (2021)

Due to the fascinating structures and wide applications, porous materials with open frameworks have attracted more and more attentions. Herein, a novel two-dimensional (2D) halogen-bonded organic framework (XOF–TPPE) was successfully designed and fabricated by iodonium-bridged N???I+???N interactions between pyridyl groups and I+ for the first time. The formation of XOF–TPPE and its linear analogue was monitored by 1H NMR, UV–Vis, X-ray photoelectron spectroscopy (XPS), IR, SEM, TEM, HRTEM and selected-area electron diffraction (SAED). The structural model of XOF–TPPE was established based on powder X-ray diffraction (PXRD) data and theoretical simulations. Significantly, synchrotron small-angle X-ray scattering (SAXS), DLS and UV–Vis spectroscopy experiments suggested that XOF–TPPE still maintains a stable 2D framework structure in solutions. This research opens up a novel avenue for the development of organic frameworks materials, and may bring new promising applications for the field of porous materials.

Selective Host–Guest Co-crystallization of Pyridine-Functionalized Tetraphenylethylenes with Phthalic Acids and Multicolor Emission of the Co-crystals

Feng, Hai-Tao,Xiong, Jia-Bin,Luo, Jun,Feng, Wen-Fang,Yang, Desuo,Zheng, Yan-Song

, p. 644 - 651 (2017)

Tetraphenylethylene (TPE) and its derivatives are the most typical and most widely studied organic compounds showing aggregation-induced emission (AIE). Due to their propeller-like structures, V-like clefts exist between the aryl rings, which make them promising host compounds. However, such a possibility is seldom explored. Herein, it is reported that TPE derivatives bearing two or four pyridine rings at the para positions of the phenyl rings (TPE-Pys) can selectively include triangular (Δ-like) m-phthalic acid from a mixture of o-, m-, and p-phthalic acids due to their shape complementary to form host–guest co-crystals, which showed redder emission than the TPE-Pys themselves. The emission of co-crystals 1–5 could be reversibly switched between yellow and red by alternating exposure to HCl and ammonia vapor. The host–guest co-crystals not only exhibited great potential for selectively recognizing and separating m-phthalic acid and as multicolor emission materials, but are also suitable for use as secret ink due to their reversible color change on varying the host–guest interactions.

Tetrapyridyl tetraphenylethylenes: Supramolecular building blocks with aggregation-induced emission properties

Kapadia, Pradeep P.,Widen, John C.,Magnus, MacKenzie A.,Swenson, Dale C.,Pigge, F. Christopher

, p. 2519 - 2522 (2011)

Two tetrapyridyl-substituted tetraphenylethylenes have been prepared via Suzuki coupling between tetrabromo tetraphenylethylene and 3- or 4-pyridine boronic acid. Both compounds exhibit aggregation-induced emission as determined by solid state fluorescenc

Divergent and Stereoselective Synthesis of Tetraarylethylenes from Vinylboronates

Stang, Peter J.,Yao, Yisen,Zhang, Minghao,Zhao, Wanxiang

supporting information, p. 20090 - 20098 (2020/09/02)

The synthesis of a new tetraborylethylene (TBE) is reported, and its application in the preparation of [4+0]-tetraarylethenes (TAEs) is elucidated. TAEs have widespread applications in material science and supramolecular chemistry due to their aggregation-induced emission (AIE) properties. The divergent and stereoselective synthesis of [3+1]-, [2+2]-, and [2+1+1]-TAEs via multiple couplings of vinylboronates with aryl bromides is demonstrated. These couplings feature a broad substrate scope and excellent functional group compatibility due to mild reaction conditions. Facile access to various tetraarylethenes is provided. This strategy represents an important complement to the conventional methods employed for the synthesis of TAEs, and would be a valuable tool for synthesizing TAE-based molecules useful in functional materials, biological imaging and chemical sensing.
