Gelation was achieved by physical crosslinking of poly(trimethyleneimine) salt (PTMI). The crosslinker 1 acted as crosslinking molecule between two secondary ammonium cation sites of PTMI. AFM image suggested that PTMI and 1 constructed ladder-like aggregate to form one-dimensional fibers. Trans-cis isomerization of the azobenzene group was induced sol-gel phase transition by UV irradiation. The structural change probably instabilizes the ladder-like aggregates due to inhibition of stacking between 1.
