Key-Enabled Molecular Rotation Modulates Intramolecular Hydrogen Bonding Toward a turn-on Trace-Level N2H4 Sensor Hydrazine (N2H4) is a highly toxic and versatile chemical raw material, has been widely used in industrial production and agricultural life, but it has also caused environmental pollution. In this research, a fuorescent probe SDG-2 was designed and synthesized for hydrazine detection through esterification functionalization of pyridinium acylion.

Thienoquinolinone as a New Building Block for Wide Bandgap Semiconducting Polymer Donors for Organic Solar Cells A new heterocyclic aromatic structure, thieno[3,2-c]quinolin-4(5H)-one (TQO), was designed and synthesized as an electron-accepting building block for donor-acceptor-type copolymers. TQO was copolymerized with 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene (BDT) to give PBDT-TQO.
