Hybrid Molecules Based on Fullerene C60 and Dithienylethenes. Synthesis and Photochromic Properties. Optically Controlled Organic Field‐Effect Transistors

Abstract

Hybrid molecules based on fullerene C60 and dithienylethene and its perfluorinated analog not inferior in the efficiency of phototransformations to the initial photochromic compounds were synthesized for the first time. The resulting pyrrolidinofullerenes containing photochromic moieties were used to fabricate organic field‐effect transistors (OFETs) with output and transfer characteristics ten times exceeding similar characteristics of devices based on staring dithienylethenes. It was found that OFETs based on hybrid molecules with dithienylethenes are four times less efficient than devices based on hybrid molecules with perfluorinated analogs.

CNT thin films based on epoxy mixtures: fabrication, electrical characteristics

“…This study extends the exploration initiated in a previous study in the development of nanocomposite thin film structures utilizing poly-arylenephthalide matrices with single-walled carbon nanotubes (SWCNT) and graphene oxide fillers [31]. It builds upon the advancements in hybrid molecular systems reported elsewhere, particularly in the synthesis of hybrid molecules incorporating fullerene C60 and dithienylethenes for optically controlled organic field-effect transistors (OFETs) [32]. Furthermore, it draws inspiration from optically controlled OFETs described in other studies utilizing photochromic spiropyran and fullerene C60 films [33][34].…”

Polyaniline Derivatives for Chemical Sensors of Ammonia Vapor

“…In the modern world, the most promising devices for monitoring gaseous media are chemical sensors-small, high-speed sensors with a fairly low cost. On the basis of thin polymer films, such gas sensors can be manufactured, including those for ammonia vapors [8][9][10][11].…”

The enhancement of the optical properties of CdS/PMMA by adding fullerence C60

“…(Artur A. Khuzin 2021) [10] Synthesize, for the first time, C60 fullerene-based composite polymers and diphenylmethane. Its per fluorinated analog was produced and proved not to be poor in the photo transformation efficiency of the original photochromic compounds.…”
