PhD student wins Chemistry Central Journal Prize

化學博士生獲頒化學中央期刊獎

PhD student Kwan Chak-shing from the Department of Chemistry of HKBU received the Chemistry Central Journal Prize for his poster presentation entitled “A Fluorescent and Switchable Rotaxane Dual Organocatalyst” at the Fifth International Conference on Molecular Sensors and Molecular Logic Gates held in University of Bath, UK from 24 to 28 July 2016. Chak-shing is the only student from among the scholars who received a prize this year, and the only Hong Kong citizen from local universities to be awarded.

Chak-shing was delighted to receive the prestigious recognition from the international conference. He said, “The conference in the UK helped broaden my horizons in various areas of chemistry. I would also like to thank my supervisor Dr Ken Leung for his guidance, support and encouragement.”

Chak-shing’s project developed the novel use of the special mechanical interlocked molecule rotaxane which could be applied to enhance the overall efficiency of drug synthesis. He combines the concepts of molecular switches and organic catalysts in chemistry to generate a catalyst named the “fluorescent rotaxane dual organocatalyst”. Upon the addition of acid/base, the new catalyst can be reversibly “switched on and off” to synthesize the desired product exclusively from a mixture of starting materials.

浸大化學系博士生關擇誠同學憑藉他的海報報吿「熒光和可切換的輪烷雙有機催化劑」,在第五屆分子傳感器與邏輯門國際會議上獲頒「化學中央期刊獎」。會議於7月24至28日在英國巴斯大學舉行。今年的得獎學者來自世界各地,擇誠是唯一來自香港及仍然在學的得獎者。

擇誠對獲得這項國際殊榮表示高興。他說﹕「是次會議有助我更了解化學的不同研究領域。我亦感謝梁湛輝博士對我的指導、支持和鼓勵。」

輪烷是一種特別的機械分子內鎖結構,可以透過不同的外在刺激來改變分子的內部結構,擇誠的研究發現輪烷的應用,可促進製藥過程的效率。研究項目結合輪烷的熒光分子開關與有機化學催化劑的概念,研究出一種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」,有效合成出一種新的混合物。
