The time taken to produce the ubiquitous and promiscuous receptor, which has become known as the little "blue box", has been halved as a result of using a pH-responsive derivative of 1,5-diaminonaphthalene to displace the template employed during its synthesis. The fact that this surrogate trades places within the cavity of the "blue box" is the key to the time-saving for the simple reason that it leaves the lock, so-to-speak, as soon as it becomes protonated by a strong acid. During the subsequent full characterisation of the "blue box", it was discovered that the tetracationic cyclophane exists at least in two different polymorphs in the solid state.
