Molecular Bottlebrushes with Bimodal Length Distribution of Side Chains
Macromolecules, 2015The structural details of bottlebrush polymers, specifically the grafting density and molecular weight distribution of side chains, influence their physical properties; however, they are difficult to analyze using conventional techniques. Herein we report the synthesis, characterization, and molecular imaging of bottlebrush macromolecules with both ...

On the relation between side chain length and RM value
Journal of Chromatography A, 1959Abstract A study was made of the R M values, given in the literature, of a wide variety of organic compounds forming homologous series. An equation is proposed in which the R M value is related to the number of carbon atoms in the members of the homologous series.

Research on the effectiveness of polycarboxylate superplasticisers with different side-chain lengths
Advances in Cement Research, 2021Polycarboxylate superplasticiser (PCSs) are commonly used and studies to enhance their compatibility with other concrete raw materials have been undertaken. However, the effect of the side-chain length (SCL) in PCSs on the properties of cement-based materials (CBMs) has not gained enough attention.

Molecular Orientation of Hairy-Rod Polyesters: Effects of Side Chain Length
Macromolecules, 1998Polarized laser Raman microscopy was employed in order to investigate the effects of side chain length on the orientability of uniaxially drawn films of a model hairy-rod polymer, as a function of draw ratio; an aromatic polyester containing terphenyl units in the main chain and aliphatic side chains (hexyl and dodecyl units) was used in the ...

Phosphatidylcholine liposomes containing cholesterol analogues with side chains of various lengths
Chemistry and Physics of Lipids, 1980The effect of the length of the side chain of sterols on their interaction with phosphatidylcholine was studied by measuring the permeability properties of liposomes constituted with sterol analogues with side chains of various lengths. The sensitivities of liposomes constituted with these sterol analogues toward digitonin and polyene antibiotics were ...

Polyprenyl diphosphate synthase essentially defines the length of the side chain of ubiquinone
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1996Ubiquinone, known as a component of the electron transfer system in many organisms, has a different length of the isoprenoid side chain depending on the species, e.g., Escherichia coli, Saccharomyces cerevisiae and humans have 8, 6, and 10 isoprene units in the side chain, respectively. No direct evidence has yet shown what factors define the length of

Langmuir, 2021
Superhydrophobic surfaces can be quickly formed with supramolecular materials. Incorporating low-molecular-weight gelators (LMWGs) with perfluorinated chains generates xerogel coatings with low surface energies and high roughness. Here, we examine and compare the properties of the xerogel coatings formed with eight different LMWGs. These LMWGs all have

Controlling the mechanical properties of hydrogels via modulating the side-chain length
Soft Matter, 2023Even though the toughness of hydrogels is usually adjusted by changing the cross-linking density and structure, or the polymer concentration, we have discovered a new strategy to control the toughness via modulating the side-chain length.

Inclusion Abilities of Bile Acids With Different Side Chain Length
Molecular Crystals and Liquid Crystals, 2001Abstract It was found that steroidal bile acids have greatly different inclusion abilities with decreasing or increasing their side chain length. Namely, the acids with intermediate side chains formed inclusion compounds with various organic compounds, while those with shorter or longer chains did not include so many.

Role of Oligoethylene Glycol Side Chain Length in Responsive Polymeric Nanoassemblies
Langmuir, 2019An oft-desired feature of a responsive nanomaterial is that it should undergo disassembly or morphological change upon application of a specific stimulus. The extent of response has been found to depend on factors such as the nature and the number of responsive functionalities incorporated into these particles. In this work, the length of oligoethylene
