Conditional Fluorescent Changes of Azaylides with Fluorescent Chromophores

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We found conditional fluorescent changes of azaylides bearing fluorescent chromophores. Azaylide formation and their stability were examined using electron-deficient aromatic azides and triarylphosphines having fluorescent chromophores. Turn-on fluorescence was realized under the acidic conditions using a non-fluorescent azaylide prepared by nonhydrolysis Staudinger reaction from 2,6-dichloro-substituted aryl azide and 1-pyrenyl phosphine.
