Design and Synthesis of Epoxidized Hemicellulose Polyether from Viscose Fiber Waste as Efficient Plasticizer for Ethyl Cellulose

Wen Sun, Yuting Ma, Ruihao Zhang, Gang Zhang et autres

Ethyl cellulose (EC) has been widely used in pharmaceutical and food packaging aspects due to its biodegradability and antimicrobial properties; however, it suffers from excessive brittleness, which must be plasticized to meet the requirement of industry. Herein, hemicellulose polyether glycidyl ether (EPPG) …

Acenaphthylene-Fused Angular and Linear π-Extension of Acridone

Xinxin Chen, Weifan Wang, Gang Zhang

The direct functionalization of small heterocyclic molecules is an efficient strategy for constructing large heteroatom-doped polycyclic aromatic systems. However, due to the unique reactivity of acridone, π-extension on the benzene ring generally leads to the formation of angular-shaped acridone derivatives. In this …

Access to N-aryl-2,2′-diindole via Fluoroarene-induced One-Pot Bicyclization Strategy with tBuOK

Guanxing Zhu, Jie Zhang, Hailong Chen, Wanwan Wang et autres

We present a systematic and concise one-pot protocol for synthesizing diversely substituted N -aryl-2,2′-biindoles with t BuOK. The fluoroarene-facilitated dual cycloisomerization of 1,3-diynylaniline enables efficient construction of target compounds under mild conditions. Substrate scope investigation revealed that fluoroarenes bearing electron-deficient substituents exhibited …

A Heptagon-Embedded Structural Isomer of Azacorannulene

Yang Ji, Zikang Ma, Lin Wan, Weifan Wang et autres

A nitrogen-doped heptagon-embedded bowl-shaped molecule that can be viewed as a structural isomer of azacorannulene was synthesized and characterized. The presence of a seven-membered ring significantly alters the molecular electronic structure and results in a distinct optical property. The pyramidalized geometry of …

Access to Sondheimer-Wong Diyne-Embedded Diaza[7]helicene with High Dissymmetry Factor Via Spontaneous Valence Isomerization

Guanxing Zhu, Tingting Ding, Hailong Chen, Jilei Liang et autres

The synthesis of Sondheimer-Wong diyne-fused diaza[7]helicene was achieved through spontaneous valence isomerization, which was a key step. Crystallographic analysis resolved the diaza[7]helicene’s absolute configuration. The P, P- and M, M- enantiomers were separated by chiral HPLC and further characterized by CD and …

Isomeric Pentagonal Fusion and π ‐Expanding of Nitrogen/Carbonyl‐Containing Multi‐Resonant Emitters for High‐Performance and Narrowband Organic Electroluminescence

Guoyun Meng, Jianping Zhou, Qi Wang, Tianyu Huang et autres

Abstract Embedding nitrogen/carbonyl (N/C═O) units into rigid heterocyclic aromatic hydrocarbons creates novel multi‐resonant thermally activated delayed fluorescence (MR‐TADF) molecules. Nevertheless, the intrinsic short‐range charge transfer (SRCT) characteristics of N/C═O derivatives, as exemplified by quinolino[3,2,1‐ de ]acridine‐5,9‐dione (QAO), result in broad spectral bandwidths, …
