Abstract

original image

The “click” trick: Many reactions are classified as click reactions even though some are limited to certain applications. Thus, there is danger that the term “click” will become meaningless over time and simply a synonym for “successful”. To prevent this, the original click criteria are evaluated in this Essay specifically for the synthetic polymer field and a set of criteria are specified that distinguishes click from other efficient reactions.
