Preparation of silver-nanoparticle-loaded C₆₀-ethylenediamine adduct microparticles and their application to photoelectric conversion

Abstract

We report here new types of suprastructure products consisting of C60-ethylenediamine microparticles and silver nanoparticles that were loaded onto the surfaces of the microparticles by electrostatic adsorption. The suprastructure products could be deposited on the surface of an indium tin oxide electrode by electrostatic deposition. These modified electrodes generated cathodic photocurrents in the presence of ascorbic acid and oxygen. The photocurrent generation behavior implies an ensemble of the electron-transfer processes of silver-nanoparticle-mediated electron transfer acting in the cathodic direction and plasmon-induced charge separation acting in the anodic direction.

Self-Assembled Supramolecular Micelles Based on Multiple Hydrogen Bonding Motifs for the Encapsulation and Release of Fullerene

“…Nevertheless, the derivatives and isomers produced after the change may lead to uncertain toxicity. There were some strategies to encapsulate C 60 to fabricate fullerene-involved composites, such as through carbohydrate polymers [14], silver nanoparticles [15], and metal-organic frameworks (MOFs) [16]. The hybrid materials and encapsulation techniques can be used for drug release, electrode fabrication, and guest molecule adoption [14][15][16].…”

The hybrid materials and encapsulation techniques can be used for drug release, electrode fabrication, and guest molecule adoption [14][15][16]. Another way is toward supramolecular complexation, but this still suffers from low complex stability and a low drug loading content (DLC)(~1 wt%) [13].…”
