合成了新型的2,10-二取代的苯并呋喃[2,3- e ]萘恶唑荧光染料的结构异构体。已经在溶液和固态下研究了植物的物理性质。的萘的吸收和荧光强度[1,2 d ]恶唑比那些吩[2,1-强得多d在溶液]恶唑。而且,在固态下,前者的发射强度通常比后者的异构体的发射强度强得多。为了了解光物理性质的差异,已进行了半经验分子轨道计算和X射线晶体学分析。

Provided are novel hetero-polycyclic compounds having a specific structure, color-changing material compositions comprising (A) a fluorescent coloring matter comprising at least one of the hetero-polycyclic compounds described above and (B) a binder material, color-changing films comprising the above hetero-polycyclic compounds, coloring matters comprising the above hetero-polycyclic compounds, and pigments or dyes comprising the hetero-polycyclic compounds described above, and provided are color-changing material compositions which are not deteriorated in a color-changing performance even after used for long time and which are prevented from being unusable due to deposition of coloring matters during storage and color-changing films produced by using the same, and novel hetero-polycyclic compounds, coloring matters and pigments or dyes which actualize them.
