The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid( cas:560-09-8 ) is researched.Related Products of 560-09-8.Shang, Weili; Zhu, Xuefeng; Liang, Tongling; Du, Cong; Hu, Liangyu; Li, Tiesheng; Liu, Minghua published the article 《Chiral Reticular Self-Assembly of Achiral AIEgen into Optically Pure Metal-Organic Frameworks (MOFs) with Dual Mechano-Switchable Circularly Polarized Luminescence》 about this compound( cas:560-09-8 ) in Angewandte Chemie, International Edition. Keywords: selfassembly achiral aggregation emitter metalorganic framework circularly polarized luminescence; aggregation-induced emission (AIE); chirality transfer; circularly polarized luminescence; mechano stimuli; metal-organic frameworks (MOFs). Let’s learn more about this compound (cas:560-09-8).

Circularly polarized luminescence (CPL) is attractive in understanding the excited-state chirality and developing advanced materials. A chiral reticular self-assembly strategy to unite achiral AIEgens, chirality donors, and metal ions to fabricate optically pure AIEgen metal-organic frameworks (MOFs) as efficient CPL materials is proposed. CPL activity of the single-crystal AIEgen MOF was generated by the framework-enabled strong emission from AIEgens and through-space chirality transfer from chirality donors to achiral AIEgens via metal-ion bridges. A dual mechano-switched blue and red shifted CPL activity was achieved via ultrasonication and grinding, which enabled the rotation or stacking change of AIEgen rotors with the intact homochiral framework. This work provided not only an insightful view of the aggregation-induced emission (AIE) mechanism, but also an efficient and versatile strategy for the preparation of stimuli-responsive CPL materials.

Author is Bisht, Kamal Kumar; Suresh, Eringathodi.

Conglomerate crystallization of achiral precursors yielding racemate metal organic frameworks/coordination polymers (MOFs/CPs) can be driven to absolute homochiral crystallization of the desired enantiomorph by using a suitable chiral induction agent. In crystallization experiments isostructural Zn and Co homochiral CPs (1P, 1M and 2P, 2M) were prepared using the achiral precursors. In the presence of enantiopure camphoric acid, the crystallization process prefers absolute chiral induction over conglomerate formation which is established by single crystal x-ray diffraction and CD spectroscopy. Crystallog. data are given.

The molecule of camphoric acid contains two, and only two, asymmetric carbon atoms, that these carbon atoms are links in a closed carbon chain, and that each of them has a carboxyl group attached to it. It is further known that the asymmetric carbon atoms are not similar to each other, so that there can be no optical inactivity by internal compensation. To distinguish between these two asymmetric atoms, the prefixes ortho- and allo-, which are commonly used in application to the two carboxyl groups are employed. A discussion on the asymmetric carbon atom to which the ortho-carboxyl group is attached as the ortho-carbon atom, and of that to which the allo-carboxyl group is united as the allo-carbon atom, is presented.

There is still a lot of research devoted to this compound(SMILES：CC1(C)[C@@H](CC[C@]1(C)C(O)=O)C(O)=O)Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, and with the development of science, more effects of this compound(560-09-8) can be discovered.
