A novel self‐assembly technique for the growth of insoluble and intractable thin organic films is presently reported. Bifunctional 8,8′‐dihydroxy‐5,5′‐biquinoline (bisquinoline) is reactively self‐assembled with diethyl zinc to form a linear coordination polymer. FTIR, UV/VIS spectroscopy, profilometry, and photoluminescence measurements were used to characterize these new multilayer films. The growth of these films on glass substrates was monitored by increasing absorbance at 396.6 nm using UV/VIS spectroscopy and by profilometry. FTIR spectroscopy indicated that the self‐assembled films are polymeric in nature. The reduction of end‐group hydroxyls and a significant red‐shift of the photoluminescence emission spectrum with respect to zinc bisquinoline powder was attributed to an increase in conjugation length.
