In order to gain deeper insight into the linkage effect and donor–acceptor effect on memory behavior (from DRAM to WORM), 4-(N-carbazolyl)triphenylamine-based polyimides and polyamides t-butyl-6FPI, t-butyl-DSPI, OMe-6FPI, OMe-DSPI, t-butyl-6FPA, t-butyl-DSPA, OMe-6FPA, and OMe-DSPA were synthesized and their memory behaviours were investigated.
