Abstract
Dynamic systems are of great interest from the perspective of mimicking biology through to preparing useful and exciting materials. Transient supramolecular gels are potentially useful, but there are limited applications that require a gel that only exists for a short length of time. Here, we show how a dynamic system can be designed to prepare materials with properties that cannot be directly accessed using the same gelator.

Transient supramolecular gels are potentially useful, but there are limited applications that require a gel that only exists for a short length of time
Dynamic systems are becoming increasingly of interest.[5,6,7,8,9,10,11,12,13,14,15]. In these dynamic gel systems, typically a supramolecular gel is formed on application of an energy input or fuel, which drives the formation of a molecule capable of forming a gel.[5,12,13,14,16,17,18,19,20]
Summary
Dynamic systems are of great interest from the perspective of mimicking biology through to preparing useful and exciting materials. But as yet unrealised, possibility is a reconfiguring of state to give a different material at the end point, for example a change from a solution to a gel, followed by formation of a different type of gel network (Fig. 1). When an aqueous solution of the enzyme was added to the vial containing a mixture of urea (in water) and gelator (in DMSO), initially the pH dropped to BpH 4.1 and a gel was formed as above (Fig. 2).
