1,7/8-Substituted isoquinoline derivatives: position isomerism caused by HIO₃-induced dehydrogenation and solid-state fluorescence stimulus-responsive properties

Abstract

A series of 1,7/8-substituted isoquinolines are designed and synthesized by the dehydrogenation reactions of 7,8-dihydroisoquinolines in the presence of iodic acid. Interestingly, the dehydrogenation products are found to be closely...

Tunable full-color emission of stilbazoles containing a 2-halo-3,4-dicyanopyridine acceptor

“…There are several publications describing synthetic methods, but only four of them report the optical properties of the compounds obtained. 47–50…”

“…Thus, it should be noted that a huge amount of data on the synthesis and application of various heterocyclic styryl derivatives has been collected to date. 19–45,47–50 However, stilbazoles with a nicotinonitrile fragment remain less studied, and there are also no data about azastilbenes with a dicyanopyridine fragment in the literature.…”
