Abstract

AbstractA new oxazoline monomer was made containing a chloroalkyl substituent which can be transformed to other functional groups by nucleophilic substitution. Oxazoline monomer containing the N‐phenothiazinyl substituent was made by reacting lithiated phenothiazine with the chloroalkyl substituted oxazoline and subsequently polymerized. N,N‐diethyl‐6‐chlorohexanamide was synthesized and N,N‐diethyl‐6‐(10‐phenothiazinyl)‐hexanamide, a model compound for the phenothiazine polymer, was made by reacting lithiated phenothiazine with this chloroamide. TCNQ did not complex with the polymer. The iodine and perchlorate complexes of the phenothiazine polymer had conductivities of 4.4 × 10 −8 and 6.9 × 10−6 S/cm, respectively, at room temperature. Each of these are higher than the corresponding values reported for complexes of the analogous model compounds or 3‐substituted phenothiazine polymer reported earlier.13, 22 This was attributed to the very short chain repeat distance for the present, symmetrically substituted polymer.
