1,7‐Diazaperylene in Organic Field Effect Transistors

Abstract

A thorough material characterization of 1,7-diazaperylene via multiple investigation techniques (cyclic voltammetry, photoluminescence, photoluminescence excitation, impedance spectroscopy) was performed to understand its applicability in organic electronic devices. The recorded data of this perylene derivative was placed in conjunction with the respective data of the parent perylene molecule, and the behavior of this novel compound in organic electronic devices (planar diodes and field effect transistors explained). Although no photovoltaic effect behavior was recorded in planar diodes where 1,7-diazaperylene was employed both as a donor as well as an acceptor, the perylene derivatives proves functional as dielectric layer in organic field effect transistors.

Pinaceae Pine Resins (Black Pine, Shore Pine, Rosin, and Baltic Amber) as Natural Dielectrics for Low Operating Voltage, Hysteresis‐Free, Organic Field Effect Transistors

“…These potential fluctuations could lead to formation of the interfacial dipoles, resulting in pronounced hysteresis between forward and reverse scans in the electrical transfer curves of the OFETs. [124] A most likely reason for electrostatically more uniform surface of the pine resins is their less hydrophilic behavior than SiO 2 . [125,126] A collection of the dielectric properties of the resins as well as the figures of merit of the fabricated OFETs containing the pine resins layers are presented in Table 6 below.…”
