Synthesis and characterization of various block copolymers using PMMA-Br macroinitiator

Melahat and Goktacs et al.

Chemical Papers, 73, 2329-2339 (2019)

Polydiacetylene functionalized with charged termini for device-free colorimetric detection of malathion.

Yunfei Zhang et al.

Journal of colloid and interface science, 528, 27-35 (2018-05-29)

We introduce 10,12-Pentacosadiynoic acid conjugated with pyridine-2-aldoxime (pralidoxime, PAM) as a positively charged amphiphilic molecule capable of forming a polymer with polydiacetylene (PDA-PAM) via 1,4-addition photopolymerization of self-assembled PAM-modified monomers. Colloidally stabilized vesicles formed by PDA-PAM and unmodified pentacosadiynoic acid

Halogenated derivatives QSAR model using spectral moments to predict haloacetic acids (HAA) mutagenicity.

Alfonso Pérez-Garrido et al.

Bioorganic & medicinal chemistry, 16(10), 5720-5732 (2008-04-15)

The risk of the presence of haloacetic acids in drinking water as chlorination by-products and the shortage of experimental mutagenicity data for most of them requires a research work. This paper describes a QSAR model to predict direct mutagenicity for

Synthesis of molten salt-type polymer brush and effect of brush structure on the ionic conductivity.

Yoshizawa M and Ohno H.

Electrochimica Acta, 46(10), 1723-1728 (2001)

Effect of heavy atoms on photochemically induced dynamic nuclear polarization in liquids.

Yusuke Okuno et al.

Journal of magnetic resonance (San Diego, Calif. : 1997), 286, 172-187 (2017-12-24)

Given its short hyperpolarization time (∼10

Use of self-assembled surfactant systems as media for a substitution reaction

Fredrik and Currie

Journal of Colloid and Interface Science, 277, 230-234 (2004)

The simultaneous role of porphyrins' H- and J- aggregates and host-guest chemistry on the fabrication of reversible Dextran-PMMA polymersome.

Seyed Milad Safar Sajadi et al.

Scientific reports, 11(1), 2832-2832 (2021-02-04)

Aggregation-induced quenching of porphyrin molecules as photosensitizer significantly reduces the quantum yield of the singlet oxygen generation, and it is able to decrease the efficacy of photodynamic therapy. We utilized amphiphilic copolymers in this work to precisely control porphyrin H-type

Metathesis Cyclopolymerization Triggered Self-Assembly of Azobenzene-Containing Nanostructure.

Wei Song et al.

Molecules (Basel, Switzerland), 25(17) (2020-08-23)

Azobenzene (AB) units were successfully introduced into poly(1,6-heptadiyne)s in order to ensure smooth synthesis of double- and single-stranded poly(1,6-heptadiyne)s (P1 and P2) and simultaneously realize the self-assembly by Grubbs-III catalyst-mediated metathesis cyclopolymerization (CP) of AB-functionalized bis(1,6-heptadiyne) and 1,6-heptadiyne monomers (M1

Stereochemical diversity in asymmetric cyclization via memory of chirality.

Takeo Kawabata et al.

Journal of the American Chemical Society, 128(48), 15394-15395 (2006-11-30)

An enantiodivergent asymmetric cyclization of N-Boc-N-omega-bromoalkyl-alpha-amino acid derivatives has been developed. With potassium amide bases in DMF, cyclization proceeds with retention of configuration, while inversion of configuration was observed with lithium amide bases in THF. Chirality of the parent amino

Use of self-assembled surfactant systems as media for a substitution reaction.

Fredrik Currie

Journal of colloid and interface science, 277(1), 230-234 (2004-07-28)

The reaction between 3-bromo-1-propanol and phenol and a series of phenols carrying substituents in 4-position was studied in micellar media and in microemulsions based on either a cationic or a nonionic surfactant. The reactivity and the yield were evaluated and

Synthesis, characterization, and NMR studies of 1,2,3-triazolium ionic liquids: a good perspective regarding cytotoxicity.

Nicolas Glanzmann et al.

Journal of molecular modeling, 24(7), 160-160 (2018-06-16)

Ionic liquids (ILs) have been extensively studied and are considered green solvents capable of replacing traditional organic solvents. In this study, seven 1,2,3-triazolium derivative ILs have been synthesized. In order to study the effect of the cation nature on the

New Eugenol Derivatives with Enhanced Insecticidal Activity.

Maria José G Fernandes et al.

International journal of molecular sciences, 21(23) (2020-12-10)

Eugenol, the generic name of 4-allyl-2-methoxyphenol, is the major component of clove essential oil, and has demonstrated relevant biological potential with well-known antimicrobial and antioxidant actions. New O-alkylated eugenol derivatives, bearing a propyl chain with terminals like hydrogen, hydroxyl, ester

Chloride-sensitive fluorescent indicators.

C D Geddes et al.

Analytical biochemistry, 293(1), 60-66 (2001-05-25)

Three fluorescent halide-sensitive quinolinium dyes have been produced by the reaction of the 6-methylquinoline heterocyclic nitrogen base with methyl bromide, methyl iodide, and 3-bromo-1-propanol. The quaternary salts, unlike the precursor molecule, are readily water soluble and the fluorescence intensity of

Post-fabrication QAC-functionalized thermoplastic polyurethane for contact-killing catheter applications.

Zachary K Zander et al.

Biomaterials, 178, 339-350 (2018-05-23)

The use of catheters is ubiquitous in medicine and the incidence of infection remains unacceptably high despite numerous advances in functional surfaces and drug elution. Herein we report the use of a thermoplastic polyurethane containing an allyl ether side-chain functionality
