Abstract:Hydrogen bonding facilitated self-assembly is an appealing strategy for constructing advanced molecular architecture. Arrays
of quadruply hydrogen-bonding (QHB) modules are especially appealing due to the reason that it features extremely strong yet reversible
and dynamic interactions. This review focus on the design and development of polymeric materials utilizing QHB arrays such as 2-
ureido-4[1H]-pyrimidone (UPy), butylurea of guanosine (UG), deazapterin (DeAP), 2,7-diamido-1,8-naphthyridine (DAN) and 7-
deazaguanine urea (DeUG). Investigating QHB interaction at molecular level and evaluate the physical and chemical properties of the resulting
material in solution and bulk are discussed. Specific examples highlighted in this review demonstrate how QHB modules are used
and incorporated into polymer matrix to yield stimuli-responsive functionalized polymer. It is discussed how QHB modules providing extra
interactions which are responsive under mechanical stress. The interactions associated with QHB modules could be effective adhesion
promoters and source of energy dissipater and can facilitate development of functional polymers and smart materials such as stimuliresponsive
polymers, novel interpenetrating polymers, polymer blends and fiber/particle reinforced polymer nano-composite.
