Hydrogen bonding responsible for self-healing properties into supramolecular polymers: a two phenyl urazole acids; b thymine/2,6-diamino-pyridine (THY/DAP); c thymine/diamino triazine (THY/DAT); d self-complementary UPy quadruple hydrogen bonding unit (dimerization constant of Kdim = 10−7–10−8 M−1 and a lifetime of 0.1–1 s); e 2-amino-3H-pyrido-(2,3-d)pyrimidin-4-one; f UPy and 2,7-diamido-1,8-naphthyridine (DAN) (UPy-DAN); g 2,7-diamido-1,8-naphthyridine (DAN) and ureido-7-deazaguanine (DeUG) (DAN-DeUG); h Hamilton wedge and cyanuric/barbituric acid wedge (HW/Ba); i low molecular weight building blocks based on a mixture of fatty diacid and triacid, form a complementary H-bonding; j brush copolymer consisting of a hard polystyrene (PS) backbones with soft polyacrylate amide (PAA) pendant groups shows dynamic microphase separation character due to the amide (PAA) hydrogen bonds and sufficient chain mobility
