Abstract
Unique temperature dependent syn-anti conformational changes in bis- and mo nozinc ethane-bridged porphyrin dimers take place in alcohol containing sol vents; these dimers adopt a syn conformation at room temperature, while a d ecrease in temperature results in the gradual shift of the conformational e quilibrium towards the anti conformer.
