Geometric (Z)- and (E)-isomers play important but different roles in life and material science. The design of new (Z)-/(E)- isomers and study of their properties, behaviors, and interactions are crucially important in molecular engineering. However, diffi
Stepwise enhancement of fluorescence induced by anion coordination and non-covalent interactions
Zhang, Dan,Zhao, Jie,Cao, Liping,Yang, Dong,Chen, Bozhong,Yu, Le,Yang, Xiao-Juan,Wu, Biao

A multi-level regulation of fluorescence enhancement upon anion coordination and subsequent binding of a guest (methyl viologen) was presented by a bis-bis(urea)-decorated tetraphenylethene (TPE) ligand with an assembly-enhanced emission characteristic.

We report that Z/E-diaminotetraphenylethylene (Z/E-2NH2-TPE) molecules suffer primarily from oxidative evolution rather than recognized isomerization. The oxide is separated and its structure is deciphered by single crystal X-ray diffraction. The oxidativ

A novel synthetic strategy gives reversible cross-linked polymeric materials with tunable fluorescence properties. Dimaleimide-substituted tetraphenylethene (TPE-2MI), which is non-emissive owing to the photo-induced electron transfer (PET) between maleimide (MI) and tetraphenylethene (TPE) groups, was used to cross-link random copolymers of methyl (MM), decyl (DM) or lauryl (LM) methacrylate with furfuryl methacrylate (FM). The mixture of copolymer and TPE-2MI in DMF showed reversible fluorescence with “on/off” behavior depending on the Diels–Alder (DA)/retro-DA process, which is easily adjusted by temperature. At high temperatures, the retro-DA reaction is dominant, and the fluorescence is quenched by the photo-induced electron transfer (PET) mechanism. In contrast, at low temperatures, the emission recovers as the DA reaction takes over. A transparent PMFM/TPE-2MI polymer film was prepared which shows an accurate response to the external temperature and exhibited tunable fluorescent “turn on/off” behavior. These results suggest the possible application in areas including information security and transmission. An example of invisible/visible writing is given.

The utilization of sulfur is a global concern, considering the abundant and cheap source of sulfur from nature and petroleum industry, its limited consumption, and the safety/environmental problems caused during storage. The economic and efficient transformation of sulfur remains to be a great challenge for both academia and industry. Herein, a room temperature conversion from sulfur to functional polythioureas was reported through a catalyst-free multicomponent polymerization of sulfur, aliphatic diamines, and diisocyanides in air with 100% atom economy. The polymerization enjoys quick reaction and wide monomer scope, which affords 16 polythioureas with well-defined structures, high molecular weights (Mws up to 242 500 g/mol), and excellent yields (up to 95%). The polythioureas can be utilized to detect mercury pollution with high sensitivity (Ksv = 224 900 L/mol) and high selectivity, clean Hg2+ with high removal efficiency (>99.99%) to achieve drinking water standard, and monitor the real-time removal process by fluorescence.

In this paper chiral polymer R-P could be synthesized by click polymerization reaction of (R)-3,3′-diethynyl-2,2′-bis(octyloxy)-1,1′-binaphthalene (R-M-1) and 1,2-bis(4-azidophenyl)-1,2-diphenylethene (M-2), and S-P was obtained by click polymerization re
Insights into the general and efficient cross McMurry reactions between ketones

The selective cross McMurry couplings of diaryl or aryl ketones with various substituted ketones were achieved in 53-94% isolated yields. It is believed that the strong affinity of the substituents to the low-valent titanium surface plays an important role in regards to moderating selectivity. Through the introduction of such substituents followed by their removal post McMurry coupling, structurally similar ketones can be effectively cross-coupled.
