Responsive Guest Encapsulation of Dynamic Conjugated Microporous Polymers

چکیده
The host-guest complexes of conjugated microporous polymers encapsulating C60 and dye molecules have been investigated systematically. The orientation of guest molecules inside the cavities, have different terms: inside the open cavities of the polymer, or inside the cavities formed by packing different polymers. The host backbone shows responsive dynamic behavior in order to accommodate the size and shape of incoming guest molecule or guest aggregates. Simulations show that the host-guest binding of conjugated polymers is stronger than that of non-conjugated polymers. This detailed study could provide a clear picture for the host-guest interaction for dynamic conjugated microporous polymers. The mechanism obtained could guide designing new conjugated microporous polymers.

Dynamic, conjugated microporous polymers: visible light harvesting via guest-responsive reversible swelling.
The light-harvesting properties of two fluorescent dynamic conjugated microporous organic polymers (Py-PP and Py-BPP) rendered with pyrene chromophores are described. The hydrophobic and dynamic nature of these porous frameworks allows the selective capture of various organic solvents by instantaneous swelling at room temperature. Moreover, the dynamic nature of these frameworks indicates the s...

متن کاملStructural insights into the functional origin of conjugated microporous polymers: geometry-management of porosity and electronic properties.
We report structural insights into the functional origin of conjugated microporous polymers (CMPs), by elucidating the vital role of linkage geometry in controlling the porosity, gas adsorption, conjugation, exciton transport and luminescence. This unprecedented yet crucial role of geometry constitutes a general principle for the rational design of CMPs.
متن کاملExtended conjugated microporous polymers for photocatalytic hydrogen evolution from water.
Conjugated microporous polymers (CMPs) have been used as photocatalysts for hydrogen production from water in the presence of a sacrificial electron donor. The relative importance of the linker geometry, the co-monomer linker length, and the degree of planarisation were studied with respect to the photocatalytic hydrogen evolution rate.
