Herein, linear water soluble cellulosic poly(protic ionic liquid) (CPIL) electrolytes were facilely and atom economically prepared after the dissolution of cellulose in the newly developed DBU/CO₂/DMSO solvent system, followed by the simple addition of succinic anhydride under mild conditions. The DBU not only participated in the dissolution of cellulose as a solvent component, but also acted as an organo catalyst for the acylation reaction of cellulose with succinic anhydride, as well as cation component in the targeted CPIL electrolytes. The reaction was optimized, and the effect of the reaction conditions on the chem. and phys. properties of the CPILs was investigated. The CPIL electrolyte aqueous solution was successfully used as the catalytic reaction media for the Knoevenagel condensation reaction. It was found that the reaction was homogeneous at the beginning, and the products could precipitate out from the media with the proceeding of the reaction, thus affording satisfactory filtration yields ranging from 56.7% to 93.8%. The solution properties of the CPIL aqueous solution were primarily investigated towards an in-depth understanding of the catalytic mechanism, by which a synergetic catalytic mechanism of the CPILs was proposed, and the reaction started with a nucleophilic addition reaction, and was then followed by a fast dehydration reaction. Finally, the direct reusability potential of the CPIL aqueous solution after the product filtration was also primarily investigated for the Knoevenagel condensation reaction.

Shin, Dong Jin;Hwang, Soon Jae;Lim, Junseop;Jeon, Chae Yeon;Lee, Jun Yeob;Kwon, Jang Hyuk research published 《 Reverse intersystem crossing accelerating assistant dopant for high efficiency and long lifetime in red hyperfluorescence organic light-emitting diodes》, the research content is summarized as follows. A highly efficient deep-red hyper fluorescence device achieving long device lifetime was fabricated by adopting a newly designed 2,5-bis(12H-benzo[4,5]thieno[2,3-a]carbazole-12-yl)-3,6-di(9H-carbazol-9-yl)terephthalonitrile (12BTCzTPN) thermally activated delayed fluorescence (TADF) assistant dopant. The 12BTCzTPN was designed via donor modification of 2,3,5,6-tetra(9H-carbazol-9-yl)terephthalonitrile (4CzTPN) to increase reverse intersystem crossing (RISC) rate for fast up-conversion. The carbazole donor moiety was replaced with 12H-benzo[4,5]thieno[2,3-a]carbazole (12BTCz) donor, which induced a small singlet-triplet energy gap and large spin-orbit coupling via the heavy atom effect of sulfur, resulting in 4.5-times faster RISC rate than the 4CzTPN TADF mol. The addition of 12BTCzTPN as an assistant dopant to a deep-red hyper fluorescence device resulted in a device with a high external quantum efficiency of 19.9% and a long device lifetime of 1312 h at 3000 cd/m2, which is up to 90% of the initial luminance.
