Chemistry PhD student wins oral presentation award

化學博士生獲演講報吿獎

PhD student Kwan Chak-shing from the Department of Chemistry won the second runner-up award with his presentation entitled “Design and Synthesis of Rotaxane Dual Organocatalyst and Derivatives” at the 24th Symposium of Chemistry Postgraduate Research held in May in Hong Kong.

Chak-shing combined the concepts of the molecular machine and organic catalysts to generate specialty rotaxane dual catalysts with a fluorescence tag. Upon the addition of acid/base, the two catalysts can be reversibly “switched on and off” to synthesise the desired product exclusively from a mixture of starting materials.

Under the supervision of Dr Ken Leung, Associate Professor of the Department of Chemistry, Chak-shing’s project highlighted the novel study of the mechanically interlocked molecule for organocatalysis.

The symposium was attended by over 600 faculty members and research postgraduate students from six local universities.

化學系博士生關擇誠同學憑藉演講報吿「輪烷雙有機催化劑衍生物的設計與合成」,在第24屆香港化學研究生研討會上獲演講報吿獎季軍。

擇誠的研究項目結合了分子機器與有機化學催化劑的概念,合成出一種特別的熒光輪烷雙有機催化劑。當改變反應體系中的酸鹼度,輪烷的雙催化效果可以「開關」,從混合起始材料中有效地合成出一種新的化合物。

在化學系副教授梁湛輝博士的指導下,擇誠致力研究機械內鎖分子有機催化劑。

會議本月初在香港舉行,共有超過600位來自六所本港大學的學者和研究生參加。
