A N^N Pt(II) bis(acetylide) complex containing coumarin was prepared in this Dalton Transactions Hot article.
The coordination chemistry of the complex was investigated to better understand its phosphorescence. Room temperature phosphorescence of coumarin has not previously been observed at room temperature, which is an exciting discovery.
The authors went on to use their complex as a sensitizer for triplet–triplet-annihilation based upconversion and luminescent oxygen sensing, with encouraging results.
