intramolecular InCl3/AgNTf2‐catalyzed regioselective domino benzannulationreaction of buta‐1,3‐diynes to build irregular nanographenes. Different nanographene compounds were easily obtained in moderate to high yields through careful design of the precursor compounds. This new domino reaction was successfully applied to a fourfold alkyne benzannulation of dimethoxy‐1,1′‐binaphthalene derivatives to arrive

1,1′-Bichrysene-2,2′-diol and its thiophene analogs, 6,6′-biphenanthro-[1,2-b]thiophene-7,7′-diols, as a series of novel π-expanded chrysene-/phenanthro[1,2-b]thiophene-based axially chiral molecules are synthesized from 1,1′-bi-2-naphthols with key steps including a Suzuki coupling, a Wittig reaction, and acid-mediated cyclization.

A glucose sensing switch is formed by water soluble conjugated polymer (PP–S-BINOL) and boronic acid-functionalized benzyl viologen (o-BBV). The two-component system shows a high sensitivity for glucose sensing with a 17-fold increase in the fluorescence intensity in the presence of 100 mM glucose.
水溶性共轭聚合物(PP-S-BINOL)和硼酸功能化苄基紫精(o-BBV)形成了葡萄糖传感开关。这种双组分系统具有很高的葡萄糖传感灵敏度,在 100 mM 葡萄糖存在下,其荧光强度增加了 17 倍。

Aggregation-induced emission enhancement and aggregation-inducedchirality inversion are two individual phenomena for the enantiomerically pure organic dyes in the aggregates. Herein we reported for the first time that these two interesting phenomena could be observed simultaneously in the aggregated states of enantiomerically pure S/R-1,1′-binaphthol annulated perylene diimides, in which two perylene

Chirality, as a fundamental symmetry property, plays an important role in molecular assembly in the solid state, impacting upon the properties and performance of organic materials. Here, heterochiral assembly was observed upon a binaphthol-basedaxiallychiral material in the thin film state, where the heterochiral assemblies of racemic mixtures exhibit superior crystallization behavior and film morphologies
