“…Organic semiconductors have been the subject of extensive research interests over the last few decades because of their potential advantages of large-area processing, low fabrication cost, molecular as well as electronic tunability, and compatibility with plastic flexible substrates. − The successful use of these materials in thin-film-based electronic devices has been the driving force for the development of new π-conjugate system. However, a greater understanding of the molecular packing and their optical and electrical properties has become essential for the fabrication of efficient organic electronic devices. − Recently, optoelectronic devices, such as organic photodiodes and phototransistors, based on organic semiconducting material have found potential applications in light detection and signal amplifications. − The major challenges with such devices are their poor photoconductivity and the stability. , Relatively large binding energy (∼0.3 to 1 eV) of the molecules prevents exciton dissociation and boosts carrier recombination. , As a result, it is challenging to improve the photocurrent for the devices based on a single layer. Various one-dimensional structures of inorganic materials have shown enhanced photocurrent and have been used for photodetection applications. − However, different derivatives of perylene diimides have been emerging as promising materials because of their significantly enhanced performances on photocurrent. ,− …”
