Abstract Interactions between the diblock copolymer poly(styrene-<i>b</i>-4-vinylpyridine) P(S4VP) and pentadecylphenol (PDP) were analysed by IR difference spectroscopy and temperature-dependent FTIR spectroscopy. Strong hydrogen bonding was found between the pyridine units of the diblock copolymer P(S4VP) and the hydroxyl groups of the amphiphile (PDP). This interaction leads to stable polymeric complexes and mesomorphic structures at two length scales. We study the nature of supermolecular interactions in the pure components as well as in the polymeric complex PDP/P(S4VP) at different temperatures ranging from room temperature up to 190 &#xb0;C. The influence of temperature on the stability of the H-bonds was studied especially in the spectral region above 3000 cm<sup>&#x2212;1</sup> (OH stretching).
