Highly Photoconducting π-Stacked Polymer Accommodated in Coordination Nanochannels

Abstract

We report on the formation of single poly(N-vinylcarbazole) (PVCz) chains in one-dimensional channels of [La(1,3,5-benzenetrisbenzoate)](n), where the side carbazolyl groups of the confined PVCz are effectively π-stacked. This ideal conformation of PVCz chains in the coordination nanochannels contributed to a drastic increase in hole mobility, which was 5 orders of magnitude higher than that in the bulk state. It is also noteworthy that PVCz isolated from the nanchannels still had a high hole mobility.

Functional conductive nanomaterials via polymerisation in nano-channels: PEDOT in a MOF

“…9,10 Similar structures from conducting polymers would benefit the development of supercapacitors, 11–13 sensor application, 14,15 non-noble metal catalysis 16,17 and fast actuation 18,19 as a result of the high internal surface area and enhanced mass transport afforded. A few conducting polymer reactions have been reported in MOFs so far, including polypyrrole, 20 poly( N -vinylcarbazole), 21 polyaniline, 22 polymethylpropylsilane 23 and polythiophene, 24 but self-standing structures of nanostructured conducting polymers are still required to be explored.…”

Autonomous motors of a metal–organic framework powered by reorganization of self-assembled peptides at interfaces

“…Previously, there reported similar examples that polymers originally polymerized in MOFs were reassembled into unusual ordered structures with unique physical properties after frameworks were removed as compared to the ones polymerized without porous frameworks due to the influence of crystalline pore arrangement of MOFs. 38,39 In another control experiment, when DPA is incubated in a MOF with the smaller pore size ([Cu 2 L 2 ted] n where L is 1,4-naphthalenedicarboxylate with pore size of 0.57 nm) that is too small to accommodate DPA peptides inside (Supplementary Information S-3), there observed no mobility indicating that DPA is necessary to be incorporated in the framework for the generation of motor activity (supplementary Information S-9). …”

Hydrothermal synthesis, crystal structure, and luminescent property of a cobalt(II) complex based on carbazole derivative

“…Supramolecular complexes built from metal ions and organic ligands have been rapidly developed over the past decades because of their fascinating structural diversities and excellent properties such as catalysis, luminescence, magnetism, electrical conductivity, molecular recognition and gas storage [1][2][3][4][5][6][7][8][9][10]. The structural topologies of the resulting supramolecular complexes are affected by many factors such as organic ligands, metal ions, synthetic methods, and so on [11][12][13].…”

“…In this work, we used a functional organic ligand containing carbazole and dicarboxylate groups, 9 ethylcarbazole 3,6 dicarboxylic acid (H 2 L), as a basic building block. Schematic drawing of the ligand is shown below: 1 The article is published in the original.…”
