Theoretical Study on the Size and the Shape of Linear Dendronized Polymers in Good and Selective Solvents

Abstract

The conformational properties of linear dendronized polymers made of a backbone and grafted dendrons are studied analytically as a function of the molecular weights of the backbone and the dendrons. Our previous model for dendritic homopolymers with a central core, is extended to include dendritic structures emerging from a linear polymeric chain made of units of different chemical nature. The ways the number of dendrons, their generation, and the functionality of their branching points affect the size and the shape both of the backbone and the dendrons are given in detail. The various effects of the quality of the solvent, capable to be different for the dendrons and the backbone, lead to interesting novel behaviors.

Solvent induced phenomena in a dendronized linear polymer

“…A further theoretical study on the size and shape of DPs in solution and various effects of the solvent quality was performed by Kosmas et al [ 23 ]. Such theoretical work based on statistical molecular mechanics lacks the assessment of the specific solvent–segment interactions for which the interaction of solvent with hydrogen-bonded residues in the branches of the dendrons may serve as an example.…”

Strict Size Specificity in Colorimetric Anion Detection Based on Poly(phenylacetylene) Receptor Bearing Second Generation Lysine Dendrons

“…For the enhancement and adjustment of the size specificity in anion recognition, one of the rational approaches should be the fine-tuning of the steric factor in the vicinity of the binding sites. For the modulation of such a steric factor, the dendron emerges as an ideal candidate for the bulky substituent capable of spatially regulating the receptor environment because significant performance has already been proven in a wide variety of chemistry fields including supramolecular chemistry. − In fact, dendronized polymers, which are linear polymers bearing dendrons at each repeating unit on the polymer chain, often exhibit a unique behavior due to the three-dimensional bulkiness of the pendant dendrons. − Therefore, the conjugation of bulky dendrons in the vicinity of the urea groups on the poly(phenylacetylene) receptor is highly expected to influence the selectivity in colorimetric anion detection.…”

Monte Carlo Simulation Studies of the Size and Shape of Linear and Star‐Branched Copolymers Embedded in a Tetrahedral Lattice

“…Extended discussions of these properties are given in feature articles for linear and star-branched homopolymers [23] , ring-shaped polymers [53] , stars in collapsed state [54] , and for other geometries including dendrimers and 2D polymers in more recent literature. [55][56][57][58][59]…”
