Solid-state photo-polymerization of unsaturated organic cations in layer perovskite halide salts
Abstract
U.v. and X-ray irradiation causes polymerization of amino-diacetylene cations R1NH3+ and H3NR2NH32+ where R1= ClCH2CC–CCCH2– and R2=(–CH2CO2CH2CC–)2 in the solid salts (R1NH3)2CdCl4 and (H3NR2NH3)CdCl4 with he layer perovskite structure; under the same conditions tetrachlorocadmate salts (RNH3)2CdCl4(R = CH2CHCH2– and CHCCH2–) do not react.
