Using molecular straps to engineer conjugated porous polymer growth, chemical doping, and conductivity

Abstract

We show that the π-face strapped repeat units, unlike conventional monomers, help to overcome the strong interchain interactions, extend network residence time, tune network growth, and increase chemical doping and conductivity in 3D-conjugated porous polymers.

π-Face strapped monomers enable self-stabilized hyperbranched π-conjugated polymer particles

“…The higher surface area to volume ratio of HB-PAMs resulting from the pancake morphology is advantageous for effective interaction with small molecule dopants for electronic and semiconducting applications. 41,68,69 The UV-vis absorption and photoluminescence spectra of p-PAM, m-PAM and HB-PAM-1 in CHCl 3 are shown in Fig. 6 and their optical properties are summarized in Table 5.…”

“…[37][38][39][40] Furthermore, we successfully synthesized conjugated porous polymer networks using adamantyl strapped building blocks and irreversible P-C bond forming reactions. 41 The incorporation of adamantyl straps not only reduced interchain π-π interactions but also enhanced the residence time of the network in the reaction mixture, resulting in a swollen network that allowed monomers to diffuse and react, enabling control over the network size and crosslinking density. 41 In this work, we report the synthesis of linear and hyperbranched strapped-polyazomethines by harnessing the power of strapped building blocks and dynamic imine chemistry.…”

Highly stretchable coaxial P3HT electrospun fibers with enhanced reversibility

“…9,11,12 To overcome these problems, several strategies have been reported in the literature, including multi-component systems, such as CPs blended with elastomers, block copolymers with elastomeric blocks, plasticizing CPs with small molecules, and coating elastomers with a CP. 4,11,13–25…”
