With the rapid development of data‐driven human interaction, advanced data‐storage technologies with lower power consumption, larger storage capacity, faster switching speed, and higher integration density have become the goals of future memory electronics. Nevertheless, the physical limitations of conventional Si‐based binary storage systems lag far behind the ultrahigh‐density requirements of post‐Moore information storage. In this regard, the pursuit of alternatives and/or supplements to the existing storage technology has come to the forefront. Recently, organic‐based resistive memory materials have emerged as promising candidates for next‐generation information storage applications, which provide new possibilities of realizing high‐performance organic electronics. Herein, the memory device structure, switching types, mechanisms, and recent advances in organic resistive memory materials are reviewed. In particular, their potential of fulfilling multilevel storage is summarized. Besides, the present challenges and future prospects confronted by organic resistive memory materials and devices are discussed.

“…For example, for exciton transport in organic thin films, it is preferable to have a structure that is oriented normal to the π–π stacking direction to ensure optimized charge injection and/or extraction . Similarly, organic FETs (OFETs) are required to have a standing‐up molecular orientation, as opposed to the lying‐down orientation in organic LEDs (OLEDs) or organic PVs (OPVs) . In addition to the above‐described advantage, sequential deposition of different organic molecules allows more complex structures such as multicomponent or multidimensional 2D–organic heterostructures.…”

The unique properties of hybrid heterostructures have motivated the integration of two or more different types of nanomaterials into a single optoelectronic device structure. Despite the promising features of organic semiconductors, such as their acceptable optoelectronic properties, availability of low-cost processes for their fabrication, and flexibility, further optimization of both material properties and device performances remains to be achieved. With the emergence of atomically thin 2D materials, they have been integrated with conventional organic semiconductors to form multidimensional heterostructures that overcome the present limitations and provide further opportunities in the field of optoelectronics. Herein, a comprehensive review of emerging 2D-organic heterostructures-from their synthesis and fabrication to their state-of-the-art optoelectronic applications-is presented. Future challenges and opportunities associated with these heterostructures are highlighted.solution-processed on any substrate inexpensively and at relatively low temperatures, which is highly advantageous for their scale-up from fundamental studies to industrial-level production. [6][7][8][9][10] Initial examples of developed organic semiconductors include field-effect transistors (FETs), [4,5,[11][12][13][14][15] photodetectors (PDs), [5,16,17] photovoltaics (PVs), [5,16,18,19] light-emitting diodes (LEDs), [5,16,20] and so on. In spite of the demonstration of promising prototypes of organic semiconductors, their development and optimization for highperformance device applications remain a challenge. In particular, it is becoming increasingly difficult to impart suitable properties to individual materials and realize appropriate physical dimensions in order to satisfy increasing demands of multifunctionality for fundamental studies, device designs, and performance optimization. [21,22] Consequently, such challenges and opportunities can be addressed by performing multidimensional integration or hybridization of organic semiconductors with various types of materials having potentially novel functionalities and unique properties.2D van der Waals (vdW) materials are the most obvious candidate for such hybridization with organic semiconductors. [22,23] Since the discovery of graphene, which opened up new avenues ranging from fundamental studies to real-world applications, [24][25][26][27] several other groups of 2D vdW materials have also been discovered, such as hexagonal boron nitride (h-BN), [28,29] transition metal dichalcogenides (TMDCs), [23,[30][31][32][33][34] black phosphorus (BP), [35][36][37][38][39][40] borophene, [41][42][43] silicene, [43] and germanene. [43] The 2D structure has been demonstrated to possess several exceptional electrical, optical, mechanical, and thermal properties vis-à-vis its corresponding bulk counterpart. [22,25,27] Most importantly, from the viewpoint of hybridization with organic semiconductors, the atomically flat and dangling-bond-free surface of 2D vdW materials not only provides an ideal int...

A new design concept for novel photoresponsive flash organic field-effect transistor (OFET) memory is demonstrated by employing the carbazoledioxazine polymer (Poly CD) as an electret. Photoactive electrets that can absorb the light effectively rather than photoactive semiconductors are proposed by the "photo induced recovery" mechanism in the literature; however, the correlation between the chemical structure and photoresponsive electrical performances is ambiguous. In this study, it is reported for the first time that the OFET memory with trapped charges can be optically recovered by a polymer electret and the working mechanism can be explained by the structural design. The highly planar Poly CD electret exhibits photoluminescence quenching in film states, resulting in the generation of sufficient excitons to eliminate trapped charges under light excitation. Additionally, the Poly CD electret with coplanar donor-acceptor moieties is suitable for both p-channel and n-channel semiconductors. For p-type memory devices, a large memory window (82 V) and stable nonvolatile retention performance with high ON/OFF ratio could be obtained. The memories also display good switching reliability for voltage-programming and light-erasing cycles. This study provides useful information for the development of polymer-based photoresponsive flash OFET memories and demonstrates the practical applications of photorecorder and photosensitive smart tag.
