Zinc bromide: a general mediator for the ionothermal synthesis of microporous polymers via cyclotrimerization reactions

“…S139†). 40,41 Ten low-melting potential Brønsted acids were also investigated (ESI Table S21, Section 6†), but only TsOH led to high-surface area DAB-CMP , consistent with previous reports. 22,26 Together, these results support that ZnBr 2 is the optimal Lewis acid for POP synthesis via aldol cyclotrimerization.…”

“…Similar to the results obtained with ZnCl 2 at 300 °C or 400 °C, the Lewis acids AlBr 3 , TiCl 4 , BiCl 3 , Zn(SO 3 CF 3 ) 2 , and SnCl 2 , along with a 3 : 1 : 1 eutectic mixture of ZnCl 2 : KCl : NaCl (100-310 °C), produced non-porous or low surface area materials, indicative of signicant degradation. Only the Lewis acids AlCl 3 (345 ± 2 m 2 g −1 ), FeCl 3 (302 ± 1 m 2 g −1 ), FeBr 3 (280 ± 2 m 2 g −1 ), and TiBr 4 (489 ± 7 m 2 g −1 ) (200-310 °C) produced porous solids with BET surface areas close to ZnBr 2 (651 m 2 g −1 ), although the sample prepared using TiBr 4 was contaminated with residual crystalline TiO 2 (ESI Fig.S139 †) 40,41. Ten low-melting potential Brønsted acids were also investigated (ESI TableS21, Section 6 †), but only TsOH led…”

Zinc Bromide: A General Mediator for the Ionothermal Synthesis of Microporous Polymers via Cyclotrimerization Reactions

“…Only the Lewis acids AlCl3 (345 ± 2 m 2 /g), FeCl3 (302 ± 1 m 2 /g), FeBr3 (280 ± 2 m 2 /g), and TiBr4 (489 ± 7 m 2 /g) (200 °C -310 °C) produced porous solids with BET surface areas close to ZnBr2 (651 m 2 /g), although the sample prepared using TiBr4 was contaminated with residual crystalline TiO2 (SI Figure S100). 40,41 Ten low-melting potential Brønsted acids were also investigated (SI Table S15, SI Section 6), but only TsOH led to high-surface area DAB-CMP, consistent with previous reports. 22,26 Together, these results support that ZnBr2 is the optimal Lewis acid for POP synthesis via aldol cyclotrimerization.…”
