Highly-efficient synthesis of covalent porphyrinic cages via DABCO-templated imine condensation reactions

Abstract

We report a new approach to construct covalent porphyrinic cages with different spacer lengths, in which the cage compounds have been conveniently synthesized in quantitative yields, via DABCO-templated imine condensation reactions.

Networked Cages for Enhanced CO2 Capture and Sensing

“…Compared with nonporous TOC, the good porous structure of pTOC might have resulted from the polymeric framework that overcome the window‐to‐arene stacking of TOC and fixed the pores position to keep the permanent porosity. The BET surface area of pTOC was higher than most of porous cages, and comparable to some emissive porous organic polymers (POPs) (Table S1, Supporting Information). The pTOC showed a steep nitrogen uptake at low relative pressure, implying the presence of micropores in their networks.…”

Outstanding Enhancement in the Axial Coordination Ability of the Highly Rigid Cofacial Cyclic Metalloporphyrin Dimer

“…This phenomenon indicates fast rotation of the DABCO molecule along the Zn II -N•••N-Zn II axis inside the cavity of Zn II -1, which is typical of the reported DABCO-coordinated Zn II -porphyrin hosts. [48][49][50][51][52][53][54] [a] The vertical distance between metal ion and the mean plane defined by four N atoms of the porphyrin macrocycles.…”

[48][49][50][51][52][53][54] The bound DABCO molecules were disordered at the two sites with half occupancy, and one site is shown. For Zn II -1, two crystallographically independent but structurally similar molecules existed in the crystal, and therefore, only one molecule is shown.…”
