Stage I: components of an N*LC polymer film. Stage II: mixture components were exposed to 365 nm for photopolymerization to form N*LC polymer film. Stage III: the N*LC polymer film was placed in hexane to wash out the liquid crystal, chiral dopant and residual monomer. SPC films embedded with chiral nanopores (SPCS or SPCR) were obtained. Stage IV: three representative luminescent dyes, including those with AIE (TPE) and ACQ (SP, perylene, C6) behavior and one kind of dye that always exhibits highly efficient emission in any state or condition (DPA), showed large glum and high Φ after loading into the SPCS or SPC R films (SPCS dye or SPCR dye). Moreover, the chiral SPC films can be recycled many times through immersion and removal of guest dye molecules.
