In the beginning, there was dark purple light at the dawn of being. Spider Woman spun lines to form the east, west, north, and south. Breath entered man at the time of yellow light. At the time of red light, man proudly faced his creator."... 

FOLLOW-UP PROBLEM 7.1 Some diamonds appear yellow because they contain nitrogen compounds that absorb purple light of frequency 7.23X10 Hz. Calculate the wavelength (in nm and A) of the absorbed light. 

Figure 5.8 The purple light emitted by hydrogen can be separated into its different components using a prism. Hydrogen has an atomic emission spectrum that comprises four lines of different wavelengths. 

Interestingly, polymer 18 was found to emit blue-purple light. Aromatic oxadiazole compounds are known to show blue electroluminescence (40-42), Main chain oxadiazole polymers can also be made fluorescent by proper modification of the chemical structure. Pei and Yang (43,44) have reported a new oxadiazole polymer 25 with both a flexible linkage and solubilizing alkoxy side-chains (Scheme 7). An LED of structure ITO/polyaniline/polymer 25/Al has an external quantum efficiency close to 0.1 % and a tum-on voltage around 4.5 V.
