Nanohybrid for Emission Constructed with Nanozone and Molecules

Nd（III）的吸收由于禁戒的f-f跃迁而较弱。我们采用8-羟基喹啉作为光敏剂，具有很强的吸收，并成功地在近红外区的光致发光，通过能量转移从激发态到Nd（III）封装在沸石腔。Nd（III）被双-全氟甲基磺酰亚胺连接以提供低振动条件。8-将喹啉醇引入到分子筛腔中，使Nd（III）产生光敏发射，在分子筛腔中形成的钌三联吡啶配合物被成功地用作光敏剂，使Nd（III）在分子筛腔中产生近红外发射。该配合物具有高的系间跃迁效率，能产生激发三重态。当Nd（III）同时引入到沸石腔中时，配合物的MLCT三重态发射被有效地猝灭，表明发生了有效的能量传递。

Absorption of Nd(III) is weak due to forbidden f-f transition. We have employed 8-quinolinol with strong absorption as a photosensitizer and succeeded in photoluminescence in near-infrared region through energy transfer from the excited state to Nd(III) encapsulated in a zeolite cavity. Nd(III) was ligated by bis-perfluoromethylsulfoarride for providing a low-vibration condition. 8-Quinolinol was introduced into the zeolite cavity, resulting in photosensitized emission of Nd(III).Ruthenium tris-bipyridyl complex formed in the zeolite cavity was successfully employed as a photosensitizer for near infared emission of Nd(III) in the Zeolite cavity. This complex shows high efficiency in intersystem crossing, giving excited triplet state. The emission from MLCT triplet state of the complex was effectively quenched when Nd(III) was introduced into the zeolite cavity together, indicating that the efficient energy transfer occurs.
