“…[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] Only in the last two years, larger PCEs (4-6%) have been reported. 43,44 More importantly, their solubility as well as optoelectronic and self-assembling properties could be finely tuned by appropriate modification. Since perylene diimide (PDI) has been widely known as an n-type organic semiconductor with high chemical, thermal and light stabilities, PDIs should be good candidates to replace fullerene in OSCs.…”

In this paper, a new perylene diimide (PDI)-based acceptor Me-PDI 4 with tetrahedral configuration (or 3D) has been synthesized and characterized. Solution-processed organic solar cells (OSCs) based on Me-PDI 4 have been investigated and our results show that the device performance can reach as high as 2.73%. Our new design with tetrahedral configuration (or 3D) could be an efficient approach to increase the PCE of OSCs with non-fullerene acceptors.

“…To date there is no report of 1D organic nanostructures that offer rapid room temperature synthesis, are compatible with large-area and flexible substrate device fabrication, can be fabricated and operated in air, and present figures of merit that can compete with inorganic materials and with commercially available photodetectors. Amongst candidate organic materials, single-crystal organic semiconductors are of particular importance as they exhibit superior optoelectronic properties, such as long range exciton diffusion12, can offer air stability1314, excellent charge carrier mobility15 and high photoconductivity16. The potential applications of photosensitive 1D organic nanostructures is broad encompassing electrophotography17, spectroscopy18, optical switches19, colorimetery20, X-ray detection21 and organic optocouplers22.…”

One dimensional single-crystal nanorods of C60 possess unique optoelectronic properties including high electron mobility, high photosensitivity and an excellent electron accepting nature. In addition, their rapid large scale synthesis at room temperature makes these organic semiconducting nanorods highly attractive for advanced optoelectronic device applications. Here, we report low-cost large-area flexible photoconductor devices fabricated using C60 nanorods. We demonstrate that the photosensitivity of the C60 nanorods can be enhanced ~400-fold via an ultralow photodoping mechanism. The photodoped devices offer broadband UV-vis-NIR spectral tuneability, exhibit a detectivitiy >109 Jones, an external quantum efficiency of ~100%, a linear dynamic range of 80 dB, a rise time 60 µs and the ability to measure ac signals up to ~250 kHz. These figures of merit combined are among the highest reported for one dimensional organic and inorganic large-area planar photoconductors and are competitive with commercially available inorganic photoconductors and photoconductive cells. With the additional processing benefits providing compatibility with large-area flexible platforms, these devices represent significant advances and make C60 nanorods a promising candidate for advanced photodetector technologies.

“…The fused bis-PDI derivatives, 2s and 2t with different alkyl chains, show air stable n-channel charge transport due to their low LUMO energy levels. 176 with a greater laterally p-extended motif is more planar and consequently has improved open air electron mobility. 178 Along with NDI and PDI derivatives, a few other aromatic diimide based OSCs were also found to exhibit n-channel characteristics.…”

Trends in molecular design strategies for ambient stable n-channel organic field effect transistors

aIn recent years, organic semiconducting materials have enabled technological innovation in the field of flexible electronics. Substantial optimization and development of new p-conjugated materials has resulted in the demonstration of several practical devices, particularly in displays and photoreceptors.However, applications of organic semiconductors in bipolar junction devices, e.g. rectifiers and inverters, are limited due to an imbalance in charge transport. The performance of p-channel organic semiconducting materials exceeds that of electron transport. In addition, electron transport in p-conjugated materials exhibits poorer atmospheric stability and dispersive transient photocurrents due to extrinsic carrier trapping. Thus development of air stable n-channel conjugated materials is required. New classes of materials with delocalized n-doped states are under development, aiming at improvement of the electron transport properties of organic semiconductors. In this review, we highlight the basic tenets related to the stability of n-channel organic semiconductors, primarily focusing on the thermodynamic stability of anions and summarizing the recent progress in the development of air stable electron transporting organic semiconductors. Molecular design strategies are analysed with theoretical investigations.
