Research strategies in click chemistry: Measuring its cognitive contents and knowledge flow

The issue about how outstanding scientists obtained innovative findings has drawn the interest of re-searchers in science, policy and scientometrics. Here, we attempt to address this question by using com-putational methods to measure the cognitive content and concepts of K. Barry Sharpless' research and estimate the knowledge flow of his click chemistry to other fields. First, we traced Sharpless' conceptual journey over time through topic modeling approach, mapping and clustering of the epistemic network from distant reading his publications. We find that connectivity and functions, the core features of click chemistry, are embodied in his constant search for simplicity. What makes simplicity possible is his con-tinuous work with collaborators on reactivity and reaction mechanisms. Moreover, citation and link anal-ysis show that click chemistry had a much richer impact on other research fields than what is generally acknowledged, and drew solutions to significant and practical questions back to chemistry from biology. Together with these findings, we propose that the click chemistry philosophy follows the way that values nature's principle. Chemistry has a clear-cut epistemic domain in modeling Nature. Thus, click chemistry as a concept on doing science beyond a connective technology goes across the boundaries between dis-ciplines and impacts many other fields.(c) 2022 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

Automated summary

This study uses computational methods to measure the cognitive content and concepts of K. Barry Sharpless' research and estimates the knowledge flow of his click chemistry to other fields. Through topic modeling, mapping, and clustering, the study traces Sharpless' conceptual journey over time and the development of the knowledge network. The findings show that click chemistry's core features of connectivity and functionality are embodied in Sharpless' constant pursuit of simplicity. Click chemistry has a significant impact on other research fields, bringing significant and practical questions back to chemistry from biology. The study suggests that click chemistry follows the principles of nature and transcends disciplinary boundaries, influencing many other fields.
