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.

"Clicking" polymers or just efficient linking: What is the difference?

Development of thermal and photochemical strategies for thiol-ene click polymer functionalization

Advances in functionalized polymer coatings on biodegradable magnesium alloys - A review.

Abstract Nature on planet earth is dominated by poly(phosphoester)s (PPEs). They structure and determine life in the form of deoxy- and ribonucleic acid (DNA & RNA), and, as pyrophosphates, they store chemical energy in organisms. Polymer chemistry, however, is dominated by the non-degradable polyolefins and degradable polycarboxylic esters (PCEs) produced on a large scale today. Recent work has illustrated the potential of PPEs for future applications beyond flame-retardancy, the main application of PPEs today, and provided a coherent vision to implement this classic biopolymer in modern applications that demand biocompatibility and degradability as well as the possibility to adjust the properties to individual needs. This comprehensive review summarizes synthetic protocols to PPEs, their applications in biomedicine, e.g., as biodegradable drug carrier or in tissue engineering, and their flame retardant properties. We highlight recent developments that may make phosphorus-based polymers attractive materials for various future applications.

Self-healing of cross-linked PU via dual-dynamic covalent bonds of a Schiff base from cystine and vanillin

Polyurethane functionalized with pendant furan moiety (FPU) was prepared using a novel chain extender (FA-FGE) which was obtained from the reaction between furfurylamine (FA) and furfuryl glycidyl ether (FGE). This furan containing PU (FPU) was grafted with maleimide functionalized polyhedral oligomeric silsesquioxanes (POSS maleimide isobutyl, POSS-M) via Diels–Alder (DA) “click” reaction. The resultant DA adducts of FPU-POSS-M hybrid material showed a remarkable increase in water contact angle (WCA) from 84° to 141.3°. This remarkable increase in the WCA is due to the combined effect of the grafting of hydrophobic POSS-M units as well as the increased micro- and nanoscale surface roughness, as evidenced by AFM and FESEM analyses. The self-healing characteristic of this organic–inorganic hybrid was evaluated by the tensile test as well as by monitoring the disappearance of the crack using optical microscopy. The formation of FPU-POSS-M hybrid material was confirmed by GPC, FT-IR, and 1H NMR analyses, and...
