Highly efficient synthesis of benzochromenone based blue luminogens via a three-component reaction of 2-hydroxychalcones, primary amines and β-ketoesters was demonstrated. The compounds show blue fluorescence with colour purity higher than 80%, thus making them viable candidates for the development of optoelectronic devices.

New Journal of Chemistry

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
