Impact of the donor structure in new D-π-A systems based on indolo[3,2,1-jk]carbazoles on their thermal, electrochemical, optoelectronic and luminescence properties

In this work, novel fluorophores with D-π-A architectures (ICz-1-ICz-6) were synthesized and investigated, where the indolo[3,2,1-jk]carbazole (ICz) framework is connected by an ethylene bridge with extensive donor moieties -e.g., fluorene, carbazole, phenothiazine, methoxyphenyl, bithiophene, and dibenzothiophene. The influences of the donor character of the substituents in the indolocarbazole derivatives on their thermal, optical and electrochemical properties were explored and compared with the quantum chemical calculations based on DFT and TD-DFT. AllICz-1-ICz-6compounds emit blue light with emission peaks between 390 and 430 nm in solution, except for compoundICz-5with a strong phenothiazine donor, which emits light at 463 nm. TheICz-6derivative with the dibenzothiophene unit features an exception to Kasha's rule. For the selected compoundsICz-2,ICz-4, andICz-5, preliminary electroluminescence tests were performed, both based on devices with a neat compound (ITO/PEDOT:PSS/ICz/Al) and with a guest-host configuration (ITO/PEDOT:PSS/PVK:PBD:ICz/Al), where two emission bands were detected covering the range from 400 to over 900 nm. Additionally, several multilayer OLED devices (ITO/PEDOT:PSS/poly-TPD/ICz-2-5/TPBi/LiF/Al) were prepared, and all diodes showed electroluminescence at 570 nm.

Efficient organic light-emitting diodes based on iridium(iii) complexes containing indolo[3,2,1-jk]carbazole derivatives with narrow emission bandwidths and low efficiency roll-offs

In this work, two cyclometalated ligands 2-(pyridin-2-yl)indolo[3,2,1-jk]carbazole (pyidcz) and 2-(4-(trifluoromethyl)pyridin-2-yl)indolo[3,2,1-jk]carbazole (tfpyidcz) containing an indolo[3,2,1-jk]carbazole unit were synthesized for achieving highly efficient iridium(iii) complexes (pyidcz)2Ir(tmd) and (tfpyidcz)2Ir(tmd) (tmd = 2,2,6,6-tetramethyl-3,5-heptanedione). The two Ir(iii) complexes exhibit emissions peaking at 499 and 554 nm, respectively, with narrow full width at half maximum (FWHM) values of 35 and 53 nm, respectively, short phosphorescence lifetimes less than 1 μs and high photoluminescence quantum yields of up to 90% in CH2Cl2solution. The organic light-emitting diodes (OLEDs) with (pyidcz)2Ir(tmd) and (tfpyidcz)2Ir(tmd) emitters show good performances. The (pyidcz)2Ir(tmd)-based device shows a turn-on voltage (Von) of 3.6 V with a maximum brightness (Lmax) of 39123 cd m?2, a maximum current efficiency (ηc,max) of 69.2 cd A?1, a maximum power efficiency (ηp,max) of 36.8 lm W?1and a maximum external quantum efficiency (EQEmax) of 21.2%. In particular, the FWHM bandwidth of the electroluminescence spectrum is only 33 nm, which was rarely reported for Ir(iii) complex-based OLEDs. The performance of the (tfpyidcz)2Ir(tmd)-based device is slightly better with aVonof 3.3 V, aLmaxof 31714 cd m?2, aηc,maxof 78.4 cd A?1, aηp,maxof 54.7 lm W?1and an EQEmaxof 24.0%. Furthermore, the efficiency roll-offs of both devices are small, and theηcvalues at 10?000 cd m?2brightness are still maintained at 60.0 and 71.4 cd A?1, respectively, which provide a powerful reference for developing indolo[3,2,1-jk]carbazole-based Ir(iii) complexes for efficient OLEDs.
