Aromatic polymers made by reductive polydehalogenation of oligocyclic monomers as conjugated polymers of intrinsic microporosity (C-PIMs)

Abstract

Incorporation of tetrabenzohepta- or -pentafulvalene connectors into soluble, aromatic polymers results in significantly different optical spectra and intrinsic microporosity.

Photocatalytic polymers of intrinsic microporosity for hydrogen production from water

“…This wettable porosity seemed to enhance the activity towards photocatalytic hydrogen production from water in the presence of a sacrificial hole scavenger, providing that the introduction of porosity did not compromise the activity in some other way. 15 Here we explore conjugated polymers of intrinsic microporosity (PIMs) [58][59][60] analogues that contain the same dibenzo[b,d]thiophene sulfone unit as porous alternative to CMPs, where the porosity arises from the inherent inability of the spiro-unit containing polymers to pack densely in the solid-state. These PIMs combine extended conjugation along the aromatic backbone with porosity, without introducing connectivity defects and twisting of the structure that are commonly observed in CMPs, and which might affect the photocatalytic activity for hydrogen production.…”

Photoactive Hybrid Materials based on Conjugated Porous Polymers and Inorganic Nanoparticles

“…[ 20 ] Few examples of linear microporous conjugated PIMs (C‐PIMs) have been reported based on twisted tetrabenzopentafulvalene (bifluorenylidene) as well as folded tetrabenzoheptafulvalene motifs, which it really is a noteworthy development. [ 21 ]…”

Ferrocene metallopolymers of intrinsic microporosity (MPIMs)

“…7 While PIMs have achieved notable success for molecular sorption and separation, 7,8 their optical and electronic properties remain largely unexplored -a consequence of the structural motifs most commonly used in PIMs, which lack backbone conjugation. 9 Several conjugated PIMs have been reported, [10][11][12][13] however, the backbone contortion that generates intrinsic microporosity in these polymers may also disrupt overlap between (intrachain) neighboring π orbitals.…”
