Ishow, E., Credi, A., Balzani, V., Spadola, F., Mandolini, L., A molecular-level plug/socket system Electronic energy transfer from a binaphthyl unit incorporated into a crown ether to an anthracenyl unit linked to an ammonium ion. Chem. Eur. J. 1999, 5, 984-989. 

A plug/socket system that deals with the transfer of electronic energy is illustrated in Fig. 7 [57]. The absorption and fluorescence spectra of a CH2CI2 solution containing equal amounts of binaphthocrown ether 4 and amine 5 indicate... 

Fig. 7 Molecular-level plug/socket system for energy transfer based on the reversible acid-base driven threading-dethreading motions in the hydrogen bonded pseudorotaxane 4d5H+ (CH2C12 room temperature). The acid-driven threading of compound 6, incorporating a bulky benzyl group, through the macrocyclic cavity of 4 does not occur [57]...

The plug-socket concept described above can be used to design molecular systems that mimic the function played by a macroscopic electrical extension cable. The operation of an extension cable is more complex than that of a plug/socket system, since it involves three components that must be hold together by two connections that have to be controllable reversibly and independently in the fully connected system, an electron (or electronic energy) flow must take place between the remote donor and acceptor units (Fig. 8). 

A second example of encapsulation is a contactless operating plug-and-socket system with integrated electronics suitable for zone 1 application (Figs 6.37 and 6.38). The system allows power and data transmission with PROFIBUS DP/VI. The socket with an integrated pigtail cable is attached to a terminal box in increased safety - e Within the socket, the 24 V DC power...

The plug/socket concept has recently been used to design and construct a self-assembling [3]pseudorotaxane that mimics at the molecular level the function played by a macroscopic extension. The system is made (Fig. 33) [140] of three components, 35 +, 36H +, and 2. Component 35 + consists of two moieties—a [Ru(bpy)3]2+ unit, which plays the role of electron donor under light excitation, and a...

All joints and connections in a system must be both mechanically and electrically suitable for use. This includes all plugs, sockets, joints and terminals and must also take account of both the environmental conditions and the location of the connections.
