Research on self-assembled metallosupramolecular architectures has bloomed in recent times. Analogous metal-free organic architectures with water solubility are highly challenging. We report here a unique class of triazine based immidazolium water-soluble metal-free interlocked organic cage (1), which was synthesized in a one-pot reaction without using dynamic covalent chemistry and without any chromatographic separation. An analogous non-interlocked cage (2) was also successfully achieved by steric control using different positional isomers of the building blocks.

Highly enantioselective Michael addition reactions of diethyl malonate to various chalcones have been achieved under mild chiral multisite phase-transfer reaction conditions by the successful utilization of 2,4,6- (triscinchoniummethyl)phenyl-1,3,5-triazines as new chiral quaternary ammonium catalysts. This simple asymmetric Michael addition process was found to be quite effective and to obtain Michael adducts with very good yields and enantiomeric excesses. Georg Thieme Verlag Stuttgart New York.
A multibranched carbazole linked triazine based fluorescent molecule for the selective detection of picric acid

A multibranched carbazole linked triazine centre based molecule (TRZ-Cz) was synthesized using the Wittig-Horner reaction and used as a fluorescent probe for the detection of picric acid (PA). The thermally more stable alkylated carbazole moiety was purposely introduced into TRZ-Cz, and could play a significant role in enhancing the thermal stability and solubility, reducing the steric hindrance, and increasing the intramolecular charge transfer (ICT) between the carbazole donor and the triazine acceptor moiety. In this paper, we employed the TRZ-Cz molecule in the detection of different nitroaromatic compounds (NACs). Among these various NACs, hydroxyl containing nitro compounds are effectively quenched; this may be due to the π-π interactions between TRZ-Cz and the acidic phenolic hydroxyl groups. The TRZ-Cz molecule exhibits a high quenching response to PA with high sensitivity and selectivity, compared to other analytes. TRZ-Cz shows good aggregation-induced emission (AIE) effects in a H2O/THF (7?:?3 v/v) mixture and these aggregates are also able to detect PA. This study offers details for the design and preparation of a new multibranched molecular fluorescent probe for the detection of PA, with low toxicity, easy synthesis steps, and high selectivity.

The first crystalline microporous zirconium phosphonate metal-organic framework (UPG-1) was synthesized using the novel tritopic ligand 2,4,6-tris(4-(phosphonomethyl)phenyl)-1,3,5-triazine. Its crystal structure was solved ab initio from laboratory powder X-ray diffraction data. UPG-1 displays remarkable thermal stability and hydrolysis resistance and has a good absorption affinity towards n-butane and CO2. This journal is

One-pot synthesis of α,β-epoxy ketones through domino reaction between alkenes and aldehydes catalyzed by proline based chiral organocatalysts
Ashokkumar, Veeramanoharan,Siva, Ayyanar
, p. 2551 - 2561 (2017)
Proline based metal free organocatalysts were developed by using a new approach for the synthesis of epoxide derivatives through a domino reaction. This domino reaction (oxidative coupling) allows a direct access to epoxides from various alkenes and aldehydes through C-H functionalization and C-C/C-O bond formation. The catalytic efficiencies of the newly synthesized organocatalysts were also determined by domino reaction in the presence of various functional groups containing aldehyde and alkene derivatives with very good yields (up to 95%) and ee's (up to 99%).
Direct Synthesis of Nanosheet-Stacked Hierarchical “Honey Stick-like” MFI Zeolites by an Aromatic Heterocyclic Dual-Functional Organic Structure-Directing Agent

Soft template designing is the most promising strategy for the synthesis of zeolite nanosheets. MFI nanosheets directed by soft templates (containing long-chain alkyl groups or aromatic groups as hydrophobic component) can be found frequently; however, so far, MFI nanosheets synthesized by soft templates with aromatic heterocycle groups (e. g., s-triazine groups) are rare. Herein, a nanosheet-stacked hierarchical MFI zeolite (NSHM) has been synthesized by using a triply branched s-triazine-based surfactant as a bifunctional organic structure-directing agent. On the basis of a geometrical match relationship, a formation model has been proposed. Synthesized NSHM had abundant mesopores stacked by nanosheets and exhibited a high surface area (430 m2 ? g?1). The 1 wt% Pd/NSHM attained a significant increase in yield of cyclohexanol/cyclohexanone mixture (from 66 to 85 %) in the oxidation of cyclohexane compared with Silicalite-1 and SBA-15 as supports.
