제목 Study on Molecular Conformation and Arrangement of CPEs as Hole Transporting Layer of Organic Optoelectronic Devices
초록 In this study, three synthesized conjugated polymer electrolytes (CPEs) with different conjugation lengths were introduced as the hole transporting layer (HTL) of organic solar cells (OSCs) and polymer light emitting diodes (PLEDs). In order to control the dipole moment of CPEs, three different spacer units were choiced. The synthesized n-type CPEs were modified to p-type CPEs by facile oxidation process. To identify the effect on electrode work function tunability by changing molecular conformation and arrangement, we simulated density function theory (DFT) calculations of these molecules and performed ultraviolet photoelectron spectroscopy (UPS) analysis for films of indium-tin-oxide (ITO)/CPEs. Additionally, we fabricated OSCs and PLEDs by using the CPEs as the HTL. As a result, the stability and performance were enhanced in the optimized devices with PFtT-D CPE HTL compared with PEDOT:PSS HTL-based devices.
