In addition, bulk heterojunction diodes made from ITO/PEDOT:PSS (CuPc-712+SQ-700+Pery-C7)/Al have been realized and studied by I–V characteristic measurements in the dark and under illumination (ITO is indium tin oxide; PEDOT:PSS is poly(3,4-ethylene dioxythiophene) oxidized (doped) with poly(4-styrene sulfonate)). Enhanced photosensitivity was observed in the photoreceptor made from the composite (CuPc-712+SQ-700+Pery-C7), which was interpreted in terms of the expansion of light absorption spectrum and to charge separation by the bulk heterojunctions. In addition, the presence of a thin PEDOT:PSS film at the ITO/(CuPc-712+SQ-700+Pery-C7) interface allows one to achieve a significant photovoltaic efficiency of 0.2%.

Pigmentation of boc-indanthrone in organic solvent/photopolymer through a thermal process / Liu, Tang-Hao in Industrial & engineering chemistry research, Vol. 49 N° 2 (Janvier 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 2 (Janvier 2010) . - pp 541–547 Titre : Pigmentation of boc-indanthrone in organic solvent/photopolymer through a thermal process Type de document : texte imprimé Auteurs : Liu, Tang-Hao, Auteur ; Wen-Tung Cheng, Auteur ; Huang, Kuo-Tung, Auteur Année de publication : 2010 Article en page(s) : pp 541–547 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Organic  solvent  photopolymer  Thermogravimetric. Résumé : This work explores a pigment converted from a latent pigment in organic solvent and photopolymer through a thermal process. Measurements by thermogravimetric analysis (TGA), ultraviolet−visible (UV−vis) spectroscopy, and Fourier transform infrared (FTIR) spectroscopy showed that regeneration of the pigment from boc-indanthrone in the solvent or photopolymer could be achieved by heating. X-ray diffraction (XRD) was employed to characterize the regenerated pigments. As shown in the results, the recrystallized structure is similar to the structure of the parent pigment. Analysis using field-emission scanning electron microscopy (FESEM) indicated that the particles of the re-formed pigment in the solvent were initially cubic, then aggregated into loose bars, and finally became firmly slated and flat for hydrogen-bonding and π−π stacking interactions. In addition, the morphology of the reproduced pigment was found to be cubic, as in the photopolymer.
