The non-luminous precursor, 2-(1-pyrenyl)-9,10-dihydro-9,10-ethanoanthracene-11,12-dione, was photochemically converted to highly-fluorescent 2-(1-pyrenyl)anthracene quantitatively in solution and in the PMMA film and the fluorescence quantum yield of the acene in benzonitrile was as high as 0.99.
不发光的前体 2-(1-芘基)-9,10-二氢-9,10-乙炔基蒽-11,12-二酮在溶液中和 PMMA 薄膜中通过光化学方法定量转化为高荧光的 2-(1-芘基)蒽,该烯在苯甲腈中的荧光量子产率高达 0.99。
