Development of organic nanoparticles with high fluorescence, good biocompatibility along with strong resistance to photobleaching through simple synthetic routes is important for diverse applications such as sensing and bioimaging. Herein, we present the development of a pyrene excimer nanoaggregate which shows aggregation induced emission (AIE) effect in a solvent mixture of THE and water. The pyrene based fluorescent probe, dimethyl-5-(pyren-1-ylmethyleneamino)isophthalate (5-DP) was synthesized through a simple single step condensation reaction from inexpensive reagents. The photophysical studies of nanoaggregated system further corroborates the AIE active behavior of 5-DP probe at different water fractions (f(w) = 0% to 90%), where the hydrogen bonding interaction between imine and water molecules led to suppression of photoinduced electron transfer (PET) inducing significant enhancement in fluorescence. The highly photostable nanoaggregates were explored as a selective fluorescence turn off sensor for phenolic nitroaromatics and the chemo-selectivity was highly pronounced for 2,4,6-trinitrophenol (picric acid), that showed efficient quenching in aqueous as well as solid phase, with a detection limit of 10 nM in aqueous medium. The quenching efficiency of the nanoaggregates can be ascribed to a combination of factors including efficient fluorescence resonance energy transfer, inner filter effect and coulombic interaction between picric acid and the aggregated probe molecules. Further, random aggregation of the pyrene derivative could be controlled for the formation of fluorescent spherical nanoparticles using Pluoronics P-123 block copolymers as encapsulating agents. The resulting composite could be used as a neoteric cell imaging probe with significantly less cytotoxicity, thus showing their potential biological applications.

Isocyanates are useful building blocks for the synthesis of amides, although their widespread use has been limited by their high reactivity, which often results in poor functional group tolerance and a propensity to oligomerize. Herein, a rhodium-catalyzed synthesis of amides is described coupling boroxines with blocked (masked) isocyanates. The success of the reaction hinges on the ability to form both the isocyanate and the organorhodium intermediates in situ. Relying on masked isocyanate precursors and on the high reactivity of the organorhodium intermediate results in broad functional group tolerance, including protic nucleophilic groups such as amines, anilines, and alcohols.

By using the reduced Schiff base tricarboxylate ligand H(3)cip, one novel 3D Cd-based coordination polymer (Cd-CP) with the formula [Cd(Hcip)(bpea)(0.5)(H2O)](n) (H(3)cip = 5-(3-carboxybenzylamino)isophthalic acid, bpea = 1,2-bis(4-pyridyl)ethane) has been solvothermally synthesized. The prepared Cd-CP possesses a 4-connected CdSO4 net based on dinuclear {Cd-2} units. Luminescence measurements revealed that the complex exhibited ratiometric turn-on luminescence responses toward Al3+ and Cr3+ with a significant color change, which could be easily distinguished by the naked eye under ultraviolet light. Cd-CP can also respond to Fe3+ through a turn-off mechanism. Interestingly, the luminescence quenched by Fe3+@Cd-CP can be recovered and increased significantly by adding some competitive Al3+, while Cr3+ can only marginally increase the luminescence intensity of Fe3+@Cd-CP. Moreover, the detection of the three aforementioned metal ions can be realized by using Cd-CP-coated test papers, extending the potential application regions of the reported material to point-of-care tests and environmental field studies.

A new triazole-functionalized tetracarboxylic acid ligand (H4L) has been synthesized and utilized for the fabrication of a 3D Zn-II organic framework with a Zn-4(-COO)(6) cluster as the secondary building unit. The framework exhibits very good thermal stability and consists of dual functionalities of exposed Lewis acidic metal sites and accessible nitrogen-donor Lewis basic sites. The Lewis basic nitrogen sites in the framework serve as CO2 binding sites for highly selective CO2 capture and the presence of exposed Lewis acidic metal sites in the framework make it an efficient heterogeneous catalyst for the chemical fixation of CO2 into value-added cyclic carbonates under ambient conditions.

In order to discover more potent antifungal, a series of 2-aryl-3,4-dihydroisoquinolin-2-iums were reasonable designed and productive synthesized by introducing benzoic acid and phenol pharmacophores into the 2-position of isoquinoline. Their structures were identified by NMR and HRMS. The preliminary in vitro antifungal results showed that most of the title compounds exhibited moderate to significant inhibitory activities against various phytopathogenic fungi at 50 mu g.mL(-1), and were equal to controls (chlorothalonil, carbendazim). The concentration of 50% inhibition rate (EC50]) of 2-(3-ethoxycarbonyl-phenyl)-3,4-dihydroisoquinolin-2-ium (4j) against R. solani was 3.8495 mu g.mL(-1), which was significantly superior to chlorothalonil (4.6328 mu g.mL(-1)). All the EC50 values of 5 compounds (7.4583 similar to 15.4495 mu g.mL(-1)) against R. cerealis were better than chlorothalonil (16.0137 mu g.mL(-1)), and 2-(4-methoxycarbonylphenyl)-3,4-dihydroisoquinolin-2-ium (4f) is the best one. The present results provide valuable information for development of plant-based antifungal agents.

Lipid migration is widespread in food system and has an important effect on food quality. It is urgent to explore the lipid migration in egg yolk after heating. The content of lipids in upper part (HL) was higher than that in bottom part (LL), and the lipids migration in yolk gel under heating were confirmed by MRI (T1) and T2 relaxation time of LF-NMR. Subsequently, the XDR result demonstrated the high lipid content induced the decrease in crystallinity of protein in HL part. The structures of HL part trend to be more ordered, stable (beta-sheet & beta-turns) and flat (alpha-helices) than LL part, also, more water distributed in LL part were observed by FTIR spectrum. The SEM results revealed that lipids migrated from LL to HL part, eventually lead to the protein in HL part of heated yolk gel unfold, the globular structure collapsed and become flatter. Morever, ethyl acetate, hexanal, etc. and hexanal, ethyl acetate, dimethyl-silanediol, etc. were identified as the main VOCs of LL and HL part of heated yolk gel, respectively. Lipid migration result in more lipid-specific volatiles were formed in the HL part, such as hexanal, 3-hydroxy-cyclohexanone, 2-pentyl-furan, D-limonene, 2-ethyl-1-hexanol, benzeneacetaldehyde. Lipid migration in heated yolk gel, caused by heat treatment, resulted in the changes of structure and flavor between HL and LL part.

Nanosized structural defects in metal-organic frameworks (MOFs) attract growing attention and often remarkably enhance functional properties of these materials for various applications. In this work, a series of MOFs [Cu-2(TPTA)(1-x)(BDPBTR)(x)] (H(4)TPTA, [1,1′:3′,1 ”-terphenyl]-3,3 ”,5,5 ”-tetracarboxylic acid; H4BDPBTR, 1,3-bis(3,5,dicarboxyphenyl)-1,2,4-benzotriazin-4-yl radical)) with a new stable radical linker doped into the structure has been synthesized and investigated using Electron Paramagnetic Resonance (EPR). Mixed linkers H(4)TPTA and H4BDPBTR were used to bridge copper(II) paddle-wheel units into a porous framework, where H4BDPBTR is the close structural analogue of H(4)TPTA. MOFs with various x = 0-0.4 were investigated. EPR studies indicated that the radical linker binds to the copper(II) units differently compared to diamagnetic linker, resulting in the formation of nanosized structural defects. Moreover, remarkable kinetic phenomena were observed upon cooling of this MOF, where slow structural rearrangements and concomitant changes of magnetic interactions were induced. Thus, our findings demonstrate that doping of structurally mimicking radical linkers into MOFs represents an efficient approach for designing target nanosized defects and introducing new magnetostructural functionalities for a variety of applications.
