Abstract
Absorption, photo- and electroluminescence spectra of some trityl substituted 1H-pyrazolo[3,4-b]quinolines derivatives (methyl- and phenyl substituted) and fabrication of the single layered organic light emitting diodes are reported. The bulky trityl substituent was introduced to prevent aggregation and crystallization of the dopant in polymer matrix. Role of ground state dipole moments in the observed red Stokes shift, electroluminescent features and photocarrier transport is explored. The maximally achieved brightness about 50 Cd/m2 is observed in the spectral range extending from 443 nm up to 462 nm. The voltage threshold was varied from 7.8 V up to 10 V. The brightness-current dependences show an existence of at least two types of carrier injections.
