Electron-Deficient Polycyclic π-System Fused with Multiple B←N Coordinate Bonds

Autor: Xiaozhou Ji, Congzhi Zhu, Alexander J. Kalin, Mohammed Al-Hashimi, Kayla P. Barker, Maciej Barłóg, Lei Fang, Yirui Cao

Publikováno v: The Journal of Organic Chemistry. 86:2100-2106

An extensive polycyclic π-system with 23 fused rings is synthesized via a highly efficient borylation reaction, in which four B-N covalent bonds and four B←N coordinate bonds are formed in one pot. B←N coordinate bonds not only lock the backbone

Design, synthesis and characterization of fused bithiazole- and dithiophene-based low bandgap thienylenevinylene copolymers

Autor: Lei Fang, Xugang Guo, Malsha Udayakantha, Dhananjaya Patra, Sarbajit Banerjee, Marc Comí, Mohammed Al-Hashimi, Xianhe Zhang, Alexander J. Kalin, Gururaj P. Kini

Publikováno v: Polymer Chemistry. 12:5942-5951

The structural rigidity of fused units in the polymer backbone, in addition to the resulting stabilizing effect of the quinoidal structure, and tunable electronic properties have played a key role in promoting highly-ordered π-stacking moieties, exh

Synthesis and Photocyclization of Conjugated Diselenophene Pyrrole-2,5-dione Based Monomers for Optoelectronics

Autor: Lei Fang, Anthony U. Mu, Michael U. Ocheje, Simon Rondeau-Gagné, Marc Comí, Alexander J. Kalin, Bailey K. Philips, Mohammed Al-Hashimi, Salahuddin Attar, Konstantinos Kakosimos

Publikováno v: Macromolecules. 54:665-672

Imide-functionalized organic monomers and polymers are attractive in organic optoelectronic devices due to the strong electron-withdrawing ability of the carbonyl units. We report the synthesis of ...

Solution-Processable Porous Nanoparticles of a Conjugated Ladder Polymer Network

Autor: E. Meir Duka, Chenxu Wang, Alexander J. Kalin, Lei Fang, Sai Che, Anthony U. Mu

Publikováno v: Macromolecules. 53:922-928

Conjugated ladder polymers possess multiple-stranded bonds which impart rigidity into their backbones. This rigidity can promote π-orbital delocalization for improved electronic and optical propert...

Aromatic porous polymer network membranes for organic solvent nanofiltration under extreme conditions

Autor: Sai Che, Jongbok Lee, Chenxu Wang, Evan R. C. Rutledge, Caili Zhang, Chenxuan Li, Alexander J. Kalin, Lei Fang, Zi-Hao Guo, Hong-Cai Zhou

Publikováno v: Journal of Materials Chemistry A. 8:15891-15899

Aromatic porous polymer networks (PPNs) are promising candidate materials for organic solvent nanofiltration (OSN) membranes, in which molecular-sieving selectivity, high permeability, and chemical/structural stability can be integrated. In this work

Rigid Ladder-Type Porous Polymer Networks for Entropically Favorable Gas Adsorption

Autor: Hong-Cai Zhou, Lei Fang, Alexander J. Kalin, Xinman Tu, Jiandong Pang, Dylan Cole, Jongbok Lee, Chenxu Wang, Sai Che, Xiaozhou Ji, Qiang Zhang, Jialuo Li

Publikováno v: ACS Materials Letters. 2:49-54

To improve methane storage capacity of porous organic materials, this work demonstrates that a rigid ladder-type backbone is more entropically favorable for gas adsorption and leads to a high gas u...

Covalent and Noncovalent Approaches to Rigid Coplanar π-Conjugated Molecules and Macromolecules

Autor: Alexander J. Kalin, Lei Fang, Congzhi Zhu

Publikováno v: Accounts of Chemical Research. 52:1089-1100

Molecular conformation and rigidity are essential factors in determining the properties of individual molecules, the associated supramolecular assemblies, and bulk materials. This correlation is particularly important for π-conjugated molecular and
