摘要: The light-harvesting properties of two fluorescent dynamic conjugated microporous organic polymers (Py-PP and Py-BPP) rendered with pyrene chromophores are described. hydrophobic nature these porous frameworks allows the selective capture various solvents by instantaneous swelling at room temperature. Moreover, indicates process visible volume expansion enhanced fluorescence. This was further explored for rapid encapsulation chromophoric guests temperature investigated photoinduced energy transfer process. resultant host–guest antenna materials showed efficient funnelling excitation host framework towards entrapped guest molecule. yielded solid-state luminescent tunable emission. work holds a great promise on design smart solids from π-conjugated small molecules optoelectronics, sensing separation.
