Diffusion across a gel–gel interface – molecular-scale mobility of self-assembled ‘solid-like’ gel nanofibres in multi-component supramolecular organogels

Abstract

The diffusion of vital components of gel nanofibres across a gel–gel interface is quantified – highly dynamic, self-assembled, two-component gels can adapt and reorganise over time.

Supramolecular assemblies of a 1,8-naphthalimide conjugate and its aggregation-induced emission property

“…Recently, several emerging properties 26,[36][37][38][39][40][41][42][43] of planar fluorophores have been observed in mixed solvents. One of them is supramolecular gelation [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61] . It is clear from the gelation table that the gelator is insoluble in water and soluble in DMSO.…”

Double diffusion for the programmable spatiotemporal patterning of multi-domain supramolecular gels

“… 6 In other work, our research group used the diffusion of two components across a gel–gel interface, that then combined to form a gel to yield interpenetrated gels. 7 …”

Spatial and temporal diffusion-control of dynamic multi-domain self-assembled gels

“…We have also previously explored the diffusion of gelator components across a gel-gel interface to yield interpenetrated two-component gels. 9 There has been some interest in diffusing acids to generate pH-responsive gels. A diffusing acid has been used to assemble an LMWGwith gel brils being aligned with the propagating acidic wave.…”
