Molecular ‘extension cable

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). 

Fig. 9 Chemical system for mimicking an electrical extension cable. Structural formulas of the three molecular components 72+, 8-H+ and 92+ (a), which self-assemble in solution (CH2C12 room temperature) to give the 72+d8-H+d92+ triad (b). In the fully connected system, excitation with visible light of the Ru-based unit of 72+ is followed by electron transfer to 92+, with 8-H+ playing the role of an extension cable [58]...

DTDP > DIDP > DINP > DOP > DIHP > DBP. Higher molecular weight esters such as trimeUitates are even more thermally stable and trimeUitate esters find extensive use in the demanding cable specifications which have strict mass loss requirements.
