The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III)(SMILESS: CC1=O[Ir+3]23([N]4=CC=C(C=CC=C5)C5=C4C6=CC=CC=[C-]36)(O=C(C)[CH-]1)[N]7=CC=C(C=CC=C8)C8=C7C9=CC=CC=[C-]29,cas:435294-03-4) is researched.Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine. The article 《Rational Molecular Design of Azaacene-Based Narrowband Green-Emitting Fluorophores: Modulation of Spectral Bandwidth and Vibronic Transitions》 in relation to this compound, is published in ACS Applied Materials & Interfaces. Let’s take a look at the latest research on this compound (cas:435294-03-4).
A series of green-emitting fluorophores based on a tetra-azaacene core is synthesized by introducing nitrile substituents at different positions. Their mol. structure-optical property relationship [i.e., vibronic transitions in photoluminescence (PL) and electroluminescence (EL) spectra] is investigated to obtain a sharp emission where the vibronic peak ν0-0 should be intensified by suppressing ν0-n (n = 1, 2, 3…) transitions. The intensity ratios (I0-1/I0-0) of the ν0-1 and ν0-0 vibronic transitions in the PL spectra of DBBNP, DBBNP2CN1, and DBBNP2CN2 in hexane are 1.13, 0.80, and 0.67, resp. Theor. calculations explain that the CN substitution at positions 8 and 13 in DBBNP2CN2 induces a uniform charge distribution and reduces the Huang-Rhys factors (HRFs) of the vibrational normal modes coupled to the electronic transition. The organic light-emitting diode (OLED) fabricated with DBBNP2CN2 shows a narrower green EL emission at 518 nm with a smaller bandwidth (50 nm) than those of devices adopting DBBNP or DBBNP2CN1. The careful modification of the mol. structures and positions of substituents enables us to reduce the HRFs of vibrations to achieve a narrow emission bandwidth with decreased I0-1/I0-0, which suggests a design strategy to develop narrowband organic fluorophores to improve the color purity for wide-gamut OLED displays.
