Coordination polymers of organic polymers synthesized via photopolymerization of single crystals: two-dimensional hydrogen bonding layers with amazing shock absorbing nature.

Crystalline coordination polymers of organic polymers (CPOPs) were synthesized via photopolymerization of Ag(I) coordination polymers of dienes which have a self-templating nature due to the formation of N-H···O hydrogen bonded layers. The shock absorbing nature of the H-bonded layer facilitated the SCSC [2+2] transformation upon irradiation to produce CPOPs.
