描述了1-（6-（二甲氨基）萘-1-基）丙-1-酮（2，5-PRODAN，2）和7-（二甲氨基）-2，3-二氢菲-4（1H）-酮3的制备。对这些化合物的物理化学性质进行了表征，并与PRODAN进行了比较。这两种化合物均显示出与PRODAN相似的溶剂化显色性，量子产率几乎小一个数量级。发射发生在具有电荷转移特征的局部激发态（LE）。不存在如PRODAN中所见的向不同电荷转移状态的内部转换。
The preparations of 1-(6-(dimethylamino)naphthalen-1-yl)propan-1-one (2,5-PRODAN, 2) and 7-(dimethylamino)-2,3-dihydrophenanthren-4(1H)-one 3 are described. The photophysical properties of these compounds are characterized and compared with those of PRODAN. Both compounds show solvatochromism that is similar in magnitude to PRODAN with a quantum yield that is nearly one order of magnitude smaller. Emission occurs from a locally excited (LE) state with charge-transfer character. There is no internal conversion to a different charge-transfer state as is seen in PRODAN.
