Nanostructured Organosilicon Luminophores for Effective Light Conversion in Organic Light Emitting Diodes

Abstract: Full characterization of nanostructured organosilicon luminophores NOL4 and NOL5 based on the donor 2,2'-bithiophene and acceptor 1,4-bis(2,2 ′ -bithiophene-5-yl)benzene units in dilute solutions and thin films by UV-Vis spectroscopy, DSC, TGA and X-ray techniques was reported. It was found that usage of these molecules as dopants (10-20 wt%) to the electroactive polyfluorene host in organic light-emitting devices (OLEDs) leads to the efficient spectral long wavelength shifting of the electroluminescence and a… Show more

“…NOLs are compatible with a range of optical polymers such as PMMA, PS or silicones [11] which allows for the creation of highly efficient plastic scintillators, spectral-shifting coatings or sheets. NOL-containing layers or optical plates have already been used for highly efficient down-shifting of light in various optoelectronic devices, such as organic light emitting diodes [12], thin film photovoltaics [13], elementary particles noble gas detectors [14] or pure CsI scintillators [15]. In this work, we report on our first results on the application of NOLs in highly efficient and fast scintillating fibres.…”

“…Электронные свойства пограничных структур на осно-ве сопряженных органических материалов представляют значительный интерес в связи с возможностями их использования в устройствах органической электрони-ки [1][2][3]. Возможным вариантом оптимизации прибор-ных характеристик органических электронных устройств является введение в состав молекул замещающих групп таких, как алкильные цепочки различной длины ли-бо поляризующие заместители [4,5].…”

“…Secondly, controlling the ratio of donor to acceptor units leads to changing the value of ε and the selfabsorption of the molecules. Previously we have reported various possible molecular architectures of NOLs [18], as well as their unique optical properties and applications in different organic photonics and optoelectronic devices [21,22]. In our recent work we examined optical properties of the NOL abbreviated as (PTPTP)Si 2 (2T-Hex) 6 , containing six 2,2'-bithienyl (2T) donor units connected via two silicon atoms to a 1,4-bis(5-phenylthienyl-2-yl)-phenylene (PTPTP, a thiophene-phenylene co-oligomer, also reported as AC5 known for its high PLQY [23][24][25]) acceptor unit [26].…”
