Fluorescence and Phosphorescence Dual-Emission Liquid Crystal Polymer Optical Waveguide for Logical Gate.

Information security has emerged as a critical concern in contemporary society. Leveraging optical logic gates with dual-emission characteristics offers a promising approach to enhancing information security. However, designing active optical waveguide materials (OWMs) capable of fluorescence-phosphorescence dual emission remains a significant challenge.

Electrochemical annulation of 1,2,3-benzotriazinones with alkynes to access isoquinolin-1(2)-ones.

An eco-friendly approach for electrochemical radical cascade annulation of 1,2,3-benzotriazinones with alkynes is described. Under catalyst-free and external reductant-free electrolysis conditions, a range of isoquinolin-1(2)-ones were obtained in moderate to good yields. Cyclic voltammetry and control studies suggest that the reaction proceeds a radical pathway.
