Optical and electrical characteristics of solvent-extracted and anisole-insoluble dyes obtained from coal tar pitch

Analyzing solid fossil-fuel pitches by a combination of Soxhlet extraction and Fourier transform ion cyclotron resonance mass spectrometry

“…Based on the molecular composition and structure of each subfraction, a more rational and economically viable utilization can be developed. For example, the bridged archipelago structures (PP-S & CTP-S representative structures in figure 5) can be directly solution-processed or further functionionalized by introducing other chemical moieties for the preparation of organic light-emitting diodes(OLEDs) [54,55]. Although it may remain empirical to predict the electronic transport and other physical properties of the devices which are made from such mixtures, product classification and quality assurance can be achieved by measuring the product performances after manufacturing.…”
