Notes:
A Series of 4′-subsituted 4-dimethylamino trans-stilbenes 1-5 was investigated by UPS, in connection with conjugated donor-acceptor substituted double bond photochemistry. The measured and assigned spectra indicate a high sensitivity, depending on the changed electronic structure by 4′-substituents of compounds 1-5. Correlation of ionization energies in LFE-relationship with Hammett's σp-values and other ground state data was proved, demonstrating UPS a powerful tool for substituent effect studies in conjugated double bond systems.
