Inkjet printing Pentacene Rubrene Thiophene

Inkjet printing is considered one of the most promising methods for controlled deposition of polymers and functional materials especially in relation to polymer-based electronic parts (deGans).... In the field of inkjet printing, use was made of hydrophobic/hydrophilic patterns to control the position of inkjet printed droplets (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] Rhetorical modification of one paper by another: Afzali 2002 – Meng 2003 coco Co-citing context:
