The Advanced Materials Program in the Division of Chemistry makes this Career award to Bowling Green University. With this award, Professor Felix Castellano will design, synthesize and characterize photochromic luminescent quenchers based on transition metal complexes dispersed in polymer matrices. Metal-to-ligand charge transfer (MLCT) excited states using a series of Ru (II) and Re (I) compounds in polymer matrices will be used for a variety of data storage applications such as write-once-read-many systems and read-write-erase systems. One- and two-photon photochemical and photophysical processes of these polymer composites will be determined to evaluate potential photonic device applications. Development of new inorganic chemistry laboratory course in partnership with a private science center will provide new education and training opportunities to students. Planned science exhibits will reach a large segment of population including students at different educational levels.Photochromic luminescent quenchers based on Ruthenium and Rhenium complexes dispersed in polymer matrices will be designed, synthesized and characterized.

化学系的先进材料项目将这一职业奖项授予鲍林格林大学。获得该奖项后，Felix Castellano教授将设计、合成和表征基于分散在聚合物基质中的过渡金属络合物的光致变色发光猝灭剂。在聚合物基质中使用一系列Ru(II)和Re(I)化合物的金属-配体电荷转移(MLCT)激发态将被用于各种数据存储应用，如一次写入多次读取系统和读-写-擦除系统。这些聚合物复合材料的单光子和双光子光化学和光物理过程将被确定，以评估潜在的光子器件应用。与一家私人科学中心合作开发新的无机化学实验室课程将为学生提供新的教育和培训机会。计划中的科学展览将覆盖很大一部分人群，包括不同教育水平的学生。基于分散在聚合物基质中的Ru和Re络合物的光致变色发光猝灭将被设计、合成和表征。这些化合物在聚合物基质中的金属-配体电荷转移(MLCT)激发态将用于各种数据存储应用。这些聚合物复合材料的单光子和双光子光化学和光物理过程将被确定，以评估其在光子器件中的潜在应用。与一家私人科学中心合作开发新的无机化学实验室课程将为学生提供新的教育和培训机会。计划中的科学展览将覆盖很大一部分人口，包括不同教育水平的学生。
