TLDR
The design of such a filigrane network requires the very careful control of chemical parameters and the reward is an assortment of different property profiles owing to the richness of possible variations.Abstract:
Air, air, air… and some solid skeleton; this is the basis for an interesting class of materials-the aerogels (shown schematically on the right). Can one therefore speak of "simple" chemistry? The design of such a filigrane network requires the very careful control of chemical parameters. The reward is an assortment of different property profiles owing to the richness of possible variations.read more

Cyclodextrin-based pseudopolyrotaxanes as templates for the generation of porous silica materials
Bao-Hang Han,Markus Antonietti +1 more
TL;DR: In this article, the in situ formed supramolecular assemblies of cyclodextrins with nonionic surfactants, poly(ethylene glycol), poly(propylene glycol) and block copolymer, so-called pseudopolyrotaxanes, were used as porogens for the generation of porous silica materials.
