A thin film comprising a polymer having linear recurring units wherein an organic group R.sup.1 is combined alternately with an organic group R.sup.2 through a bivalent bonding group, wherein each of said group R.sup.1 and said group R.sup.2 has a valence of at least 2 and has at least 2 carbon atoms; each of said linear recurring units having at least one hydrocarbon-containing group R.sup.3 having 10 to 30 carbon atoms bonded with covalent bond, and a device having the thin film. The thin film of the invention is formed by building-up layers of the above polymer by LB technique, and the obtained film can be subjected to ring closure and to elimination of a known LB compound added as occasion demand by heat treatment to provide a thin film having a thickness of not more than 10,000 .ANG. and excellent heat resistance, chemical resistance and mechanical properties, and the device having the thin film is useful particularly as electric and electronic devices.
