## Abstract Three porphyrins 2, 3, and 4, related to Hans Fischer's octaethylporphyrin 1, but with unsubstituted pyrrole β‐positions were synthesized via the biladiene pathway. The ring‐closing reaction to form the porphyrin reveals a conformational control, called __helical effect__. These new por
Norbornene building BLOCKs formed by the reaction of porphyrin 1,3-dienes with norbornadiene or dimethyl tricyclo[4.2.1.0 2,5 ]nona-2,7-diene-3,4-dicarboxylate were coupled with an ester-activated cyclobutene epoxide BLOCK to afford the first examples of hinged porphyrin-spacer-acceptor dyads. Simil
