祝賀邵偉博士！
該工作與胡文平教授課題組進行了長期的合作
（2005年-2014年），長達十年之久。該思路自2005年在中科院化學所提出，并曾于2005年在基金委化學部申請國家自然科學基金項目（遺憾，未獲得批準），但是堅持由課題組的趙軍釵博士，段小麗博士和邵偉博士先后與胡文平教授課題組進行了艱苦的摸索和反復的實驗，在2006年初取得了初步的成功，在2007年底-2008年初完成了基本的原位測試工作。這是一篇Science的工作！
Organic field-effect transistors (OFETs) are used to directly “touch”
the movement and dynamics of polymer chains, and then determine T
g.
As a molecular-level probe, the conducting channel of OFETs exhibits
several unique advantages: 1) it directly detects the motion and
dynamics of polymer chain at T
g; 2) it allows the
measurement of size effects in ultrathin polymer films (even down to
6 nm), which bridges the gap in understanding effects between surface
and interface. This facile and reliable determination of T
g of polymer films and the understanding of polymer chain dynamics guide a
new prospect for OFETs besides their applications in organic
electronics and casting new light on the fundamental understanding of
the nature of polymer chain dynamics.
