Glucose-cored poly(aryl ether) dendron based low molecular weight gels: pH controlled morphology and hybrid hydrogel formation

Abstract

We designed poly(aryl ether) dendron based transparent hydrogels containing glucose moiety, which undergoes in situ transition from nanofibers to spherical aggregates, upon pH variation. The process is reversible and the assembled structures have been characterized by DLS and SEM. More importantly, efficient dispersion of graphene oxide results in lower CGC (0.08 wt%) value and higher mechanical strength, compared to the native gel.

“…In addition, another type of hydrogel system from glucose‐cored poly(benzyl ether) dendrons was also reported by the same group. pH‐induced gel–sol transition of the supramolecular hydrogel was observed 87…”

“…23). 149 Compound 38a formed gel at a mgc value of 0.1% (w/v) in DMSO-water systems (1 : 9), while compound 38b did not show gelation in the above mixture of solvents. Rather, compound 38b immobilized alcoholic solvents to result in translucent organogels.…”

“…Measurement of the rheological parameters is critical to judge the gelation process. [75][76][77][78] To investigate the effect of the solvents, the gels separately prepared in n-hexane and n-decane were considered for the rheological study (see the ESI †). In both solvents, the materials were observed as gels since G 0 > G 00 for all the frequencies tested, and hence, we could say that the gelator in both solvents was crosslinked.…”

“…Geometry optimization and calculation of geometry, charge, energy and physicochemical characteristics (e.g., logarithm of octanol-water partition coefficient log P) of all individual molecules and complexes were carried out online using the ChemoSophia soware and the original MOPS algorithm [73][74][75][76][77][78] with continual account of solvents.…”
