Wang, Wenbo published the artcileTricycloquinazoline-containing 3D conjugated microporous polymers and 2D covalent quinazoline networks: microstructure and conductivity, Synthetic Route of 1885-29-6, the main research area is tricycloquinazoline conjugated microporous polymer covalent quinazoline network microstructure conductivity; gas adsorption hydrogen evolution reaction electrocatalyst.
Conjugated microporous polymers (CMPs) and covalent triazine frameworks (CTFs) with conjugated linkages and nanochannels have been showcased as a new platform in extensive fields. Here, by tuning the geometry of the N-rich skeleton tricycloquinazoline (TQ) unit, isomers of the 3D amorphous conjugated microporous polymer (TQ-CMP) and 2D laminar covalent quinazoline network (TQ-CQN) are synthesized. The derived diverse microstructure and elec. conductivity related to the applications of gas adsorption and the hydrogen evolution reaction (HER) are systematically discussed. TQ-CMP fabricated with an internal crosslinking network reveals a notable uptake of 25.6 wt% CO2 and of 2.91 wt% CH4 at 273 K and 1 bar, higher than most reported POP materials, which could be attributed to the higher BET surface area (781.0 m2 g-1) and dispersed pore size (1.1 nm to 13.1 nm) for guest mol. absorption. In contrast, both the modulated electronic structure of the precise π-conjugate planes and the vertically ordered one-dimensional channels endow TQ-CQN with more built-in catalytic sites and rapid electron transmission for the HER. Without any noble metal doping, the excellent catalytic activity and faster reaction kinetics of TQ-CQN are epitomized by the achieved lower overpotential of 80 mV and the Tafel slope of 40 mV dec-1.
