The Purification, Analysis And Growth Of Single Crystals Of Organic Semiconductors, Melvin Leonard Druin
Theses
The purpose of this investigation was to design and construct a furnace for growing large single crystals of organic compounds by slow crystallization from the melt by the Bridgman technique. The crystals obtained by this furnace will be used in a later investigation of the intrinsic electrical and optical properties of organic semiconductors.
The methods describe have been used width success to produce large single crystals of anthracene and ethyl-p aminobenzoate with diameters of 1/2 inch.
The most promising methods of purification of anthracene, which were chemical synthesis, washing, recrystallization from solvents, sublimation, dimerization, co-distallatian and zone refining have been …
