“…Currently, the research on biocompatibility of OSCs for bioelectronic applications is in its embryonic stage, and the scarcely available data is often incomplete. [287] So far, biocompatibility studies have been investigated for polythiophene derivatives, such as PEDOT, [288,289] P3HT, [290][291][292] polyaniline, [293] and polypyrrole. [294] Among these, PEDOT has proven to be biocompatible in vivo while introduced in a nerve interface that remained stable for over 7 months.…”

“…More recently, Chetyrkina et al studied the biocompatibility of five different vat dyes commonly used for textile coloration, as prospective OSCs for wearable and on-skin electronics. [287] The authors systematically studied the biocompatibility of the vat dyes by analyzing diverse parameters such as cell count, cell morphology, DNA damages, formation of reactive oxygen species and inflammatory response. Human embryo lung fibroblast cells were incubated in direct contact with thin films of studied OSCs for up to 14 days, and the results indicated that two of the dyes-vat blue 20 and vat orange 9, were almost nontoxic since the response of cells was very similar to control samples.…”

Electronic devices that can physically disappear in a controlled manner without harmful by-products unveil a wide range of opportunities in medical devices, environmental monitoring, and next-generation consumer electronics. Their property of transience is indispensable for mitigating the global problem of electronic waste accumulation. Additionally, transient technologies that are biocompatible and can be biologically resorbed are of great potential for applications in temporary medical implants, since it eliminates the need for expensive device recovery surgery. Transistors are the key building blocks of modern electronics, and their fabrication using organic materials is beneficial due to their low cost, unprecedented flexibility and facile processing. This contribution reviews the technological application of biodegradable materials in four major classes of organic transistors, namely organic field-effect transistors (OFETs), organic synaptic transistors, electrolyte-gated OFETs, and organic electrochemical transistors. The fundamental biodegradation mechanism is discussed in detail, followed by a perspective of various biodegradable materials utilized as active semiconductors, dielectrics, electrolytes and substrates in the various types of organic transistor devices. This contribution comprehensively discusses the role and application of biodegradable materials in all of the key modern-day organic transistors, highlighting their unique properties that allow the fabrication of biodegradable, eco-friendly, and sustainable devices.

Functionalized fullerenes are known as high-performance molecules. Herein, the interaction of C60 fullerene with Phenyl-C61-butyric-acid-methyl-ester (PCBM) is investigated by means of density functional theory (DFT) method to elucidate the structures and electronic states of C60-PCMB complexes. C60-PCBM blends are typically used in solar cell. Studying the electronic structure of C60-PCBM is important for elucidating the mechanism of solar cells. The intermolecular distances for C60 and PCBM dimers were calculated to be 3.70 and 2.34 Å, respectively. In C60 dimer, the five membered ring of C60 interacted with the six membered ring of neighbour C60. Two hydrogen bonds between side chains of PCBM are connected in the PCBM dimer. The binding energies were 1.4 kcal/mol (C60 dimer) and 2.6 kcal/mol (PCBM dimer). In the C60-PCBM complex, five different structures were found to be stable. The binding energies were distributed in the range 1.6-3.7 kcal/mol. The electronic states and excitation energies of C60-PCBM complexes and the basis set superposition error (BSSE) were discussed on theoretical results.

Exploring and researching low-cost, environmentally friendly, and sustainable organic semiconductor materials are of immense significance in various fields, including electronics, optoelectronics, and energy conversion. Unfortunately, these semiconductors almost have poor charge transport properties which range from ~ 10-4cm2V-1 s-1 to ~ 10-2 cm2 V-1 s-1. Vat orange 3, as one of these organic semiconductors, has great potential due to its highly conjugated structure. In this work, high-quality multilayered Vat Orange 3 crystals with two-dimensional growth on h-BN surfaces with thickness of 10 ~ 100 nm were obtained by physical vapor transport (PVT). Raman’s results confirmed the stability of the chemical structure of Vat orange 3 during growth. Furthermore, by leveraging the structural advantages of two-dimensional materials, an organic field effect transistor (OFET) with 2D vdW vertical heterostructure was further realized with h-BN encapsulation and multilayered graphene contact electrodes resulting in an excellent transistor performance with On/Off radio of 104 and high field-effect mobility of 0.14 cm2v-1s-1. Our results show great potential of Vat orange 3 with two-dimensional structures in future nano-electronic applications. Furthermore, we showcased an approach that integrates organic semiconductors with two-dimensional materials, aiming to offer new insights into the study of organic semiconductors.
