Radical ion pair in carrier generation process of photoconductive organic polymer films
نویسندگان
چکیده
A concept of the ion pair with the interionic distance (r0) of 2–3 nm in carrier generation process of photoconductive polymer films has been believed for a long time. Recently, however, the experimental and theoretical results denying the distant ion pair born from thermalization have been reported. This brief review describes our paper addressing the controversy over the ion pair in photoconductive polymer films, which proves the presence of distant ion pair of r0 = 0.8–0.9 nm by employing time-resolved electron paramagnetic resonance spectroscopy.

Highly transparent and homogeneous hybrids containing a single nano-sized inorganic oxide domain were synthesized from poly(methyl methacrylate) (PMMA) and aqueous dispersed zirconium oxide nanocrystals (ZrO2-NCs) in the presence of a coupling agent, 3-(methacryloxy)propyl-trimethoxysilane (MPTS), which was grafted onto the surface of ZrO2-NCs by zirconium hydroxide (Zr-OH) surface groups. The ...

The fabrication of structured polymer/nanoparticle composite films through a combination of additive, subtractive and self-assemblymethodologies is investigated. Consumer grade inkjet printing hardware is employed to deposit cationic polyelectrolytes on (i) hydrophilic and (ii) hydrophobised glass substrates. The hydrophobisation process controls the spreading of the droplets and hence the late...
