摘要：

Unique temperature dependent syn-anti conformational changes in bis- and monozinc ethane-bridged porphyrin dimers take place in alcohol containing solvents; these dimers adopt a syn conformation at room temperature, while a decrease in temperature results in the gradual shift of the conformational equilibrium towards the anti conformer.
