A new porous organic polymer containing Tröger's base units: Evaluation of the catalytic activity in Knoevenagel condensation reaction

The classic Tröger's base polymerization of a diamine and dimethoxymethane with trifluoroacetic acid as catalyst generated a Tröger's base-type polymer (TBP), which exhibited the absolute insolubility in a variety of organic solvents because of its highly aggregated model. A new porous organic polymer was obtained by a simple Tröger's base polymerization reaction between a diamine and formaldehyde in the form of acetal in the presence of...
