Electrochromic properties of a poly(dithienylfuran) derivative featuring a redox-active dithiin unit [PDF]
, 2012 A teraryl monomer containing a 1,4-dithiin-furan central unit has been synthesised and characterised by single crystal X-ray crystallography. The di(thienyl)furan monomer 11 was successfully polymerised electrochemically and shown to possess a lower ...

Journal of the Society for Information Display, EarlyView.Two complementary molecular design strategies are proposed to independently enhance operational stability and device efficiency in MR‐TADF OLEDs. Strengthening the cationic bond dissociation energy (BDEf+) improves intrinsic molecular robustness and prolongs device lifetime, although a PSF‐based efficiency‐oriented design with high molar absorption ...

2,3-Bis(4-bromophenyl)quinoxaline [PDF]
Acta Crystallographica Section E Structure Reports Online, 2007 The title compound, C(20)H(12)Br(2)N(2), was prepared by the reaction of 1-(3-bromo-phen-yl)-2-(4-bromo-phen-yl)ethane-1,2-dione with o-phenyl-enediamine in refluxing ethanol. In the mol-ecule, all bond lengths and angles are within normal ranges. The dihedral angle between the two benzene rings is 34.89 (1)°.
