“…Similar behavior of PL was previously noticed in our study of morphological stabilization of amorphous films by UV light of N,N ′-bis(3-methylphenyl)-N,N′-bis(phenyl)benzidine (TPD), another well-known OLED material [21], and by other authors before us [22,23]. DPVBi and TPD have similar characteristics like molecular structure, UV-vis absorbance [24,25] and glass transition temperatures [26,27], but changes under UV light and oxygen are faster in DPVBi, what makes it easier to study.…”

“…Ozračivanje filmova u vazduhu dovodi do postepenog smanjenja obe apsorpciona maksimuma u regionu od 325-400 nm. Pad vrednosti apsorpcionih maksimuma je posledica foto-oksidacije filma: pobuđeni TPD molekuli interaguju sa molekulima kiseonika koji su difundovali u film [17]. Uticaj UV zračenja na fotoluminescenciju istog filma prikazan je na Slici 2 u vidu serije spektara dobijenih za različito vreme ozračivanja.…”

“…Ostala dva molekula (dati na Slici 4c) izabrana su zbog prethodnih rezultata masene spektroskopije, koji su pokazali postojanje dve nove mase u spektru TPD filmova osvetljenih UV svetlošću [17]. Nove mase su veće od molekulske mase TPD molekula za 14 gmol -1 i 16 gmol -1 .…”
