As noted in Section 2, Rapson, Shuttleworth and van Niekerk first reported the formation of 2 1 adducts of tetraphenylene with a variety of solvent molecules In their 1944 paper on the molecular structure determination of 7 , Karle and Brockway stated that the sample contained 10% benzene which was removed by placing the sample in the nozzle and heating it to 200° in a vacuum before electron diffraction photographs were taken. Understandably, the nature of molecular association in these adducts drew no attention at that time, since the concept of clathration was not clarified until Powell s pioneering study of the hydroquinone (quinol) clathrates in 1947 Nevertheless, it is surprising that the problem lay dormant for the next several decades.
