Tuning MOFs: When a metal-organic framework (MOF) with an ordered three-dimensional macroporous structure is integrated into a film, the resulting materials have an additional optical element, which can be used as a general and effective signal transducer. This, in combination with the hierarchical pore structure, makes these films interesting dynamic photonic materials with potential applications in sensors.

Carbon sandwich: When a pyrrole‐containing surfactant is polymerized between layers of silica (see picture; pyrrole is red), subsequent carbonization and removal of the silica template yields large, pure, single‐layer graphene sheets. The procedure, which employs mild conditions, is controllable and can be used to produce micrometer‐sized graphene sheets on a gram scale.

A new concept for anion detection in a handy, rapid, and sensitive way is described based on the combination of the unique properties of both ILs and photonic crystals. By simple counteranion exchanging of the pendant IL units, the 3D highly ordered IL porous structure can directly sense different anions and easily convert the anion detection events into readable optical signals with color changes.

A general protocol based on spontaneous adsorption of cucurbit[n]uril (CB[n]) molecules through a strong multivalence interaction between CB[n] and gold is described, by which the formation of self-assembled CB[n] monolayers on gold surfaces can be efficiently achieved.
