Stephen Lee (Chinese: 李中漢; pinyin: Lǐ Zhōnghàn; born 25 October 1955) is an American chemist.

[1] Lee attended the International School of Geneva, Switzerland and Yale University, from which he graduated with a BA in 1978.

[citation needed] In addition, he has received an award from the Alfred P. Sloan Foundation for his continued research.

This has been considered part of Lee's philanthropic work, as he teaches these summer courses probono.

Lee is also researching ways to introduce cross-linkable guests (such as di-isocyanides or disilyltriflates) which will react with nucleophilic groups, leading to a fully covalent organic porous solid.
