祝贺邵伟博士！

该工作与胡文平教授课题组进行了长期的合作 （2005年-2014年），长达十年之久。该思路自2005年在中科院化学所提出，并曾于2005年在基金委化学部申请国家自然科学基金项目（遗憾，未获得批准），但是坚持由课题组的赵军钗博士，段小丽博士和邵伟博士先后与胡文平教授课题组进行了艰苦的摸索和反复的实验，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测试工作。这是一篇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.
