With this CAREER award, the Chemical Synthesis program is supporting the research of Professor Corey Stephenson of Boston University. Professor Stephenson will develop green chemical methodologies mediated by visible light sensitization. These operationally simple, catalytic methods forgo the need for specialized photochemistry equipment, utilizing inexpensive household light bulbs and energy efficient LEDs for irradiation. First, a general, catalytic approach to radical chemistry will be developed taking advantage of ligand dependent redox properties of ruthenium and iridium polypyridine complexes. Second, a catalytic approach to the activation of carbon-oxygen bond towards nucleophilic displacement reactions will be developed. Professor Stephenson will also be initiating educational outreach projects which interweave research and teaching. The first project involves the development of workshops for underrepresented minority/low-income high school students from the Boston area. The second program aims to promote chemistry career awareness for undergraduate and graduate students at Boston University with the creation of a special seminar series featuring speakers from academia and industry.

有了这个职业奖，化学合成计划支持波士顿大学的科里斯蒂芬森教授的研究。斯蒂芬森教授将开发由可见光敏化介导的绿色化学方法。这些操作简单的催化方法不需要专门的光化学设备，使用廉价的家用灯泡和节能LED进行照射。首先，一个一般的，自由基化学的催化方法将开发利用钌和铱多吡啶配合物的配体依赖的氧化还原性能。第二，将开发一种用于活化碳-氧键朝向亲核置换反应的催化方法。教授斯蒂芬森也将启动教育推广项目交织的研究和教学。第一个项目是为波士顿地区代表性不足的少数民族/低收入高中生举办讲习班。第二个项目旨在促进波士顿大学本科生和研究生的化学职业意识，并创建了一个特别的研讨会系列，其中包括来自学术界和工业界的演讲者。
