Rubrene single-crystals
Example of an emerging research front (2004)
Inkjet printing is considered one of themost promising methods for controlleddeposition of polymers and functionalmaterials especially in relation topolymer-based electronic parts (deGans).
. . . In the field of inkjet printing, use wasmade of hydrophobic/hydrophilic patternsto control the position of inkjet printeddroplets (Wang).
Co-citation context analysis
The highest OFETs mobilities have been reported for vacuum-deposited crystalline films or single-crystals of low-molecular weight species and in particular pentacene-based transistors have received special attention [Meng 2003] The main drawback of pentacene is very low solubility in organic solvents and it is not suitable for low-cost integrated circuit technology. Some attempts have focused on preparing thin-films of a soluble pentacene precursor which is converted to pentacene upon heating [Afzali 2002]
