Synthesis and Photochemistry of trans-trans-1,4-Diphenyl-1,3-butadiene-1-C13

Abstract

The photochemistry and photophysics of the α,ω-diphenylpolyenes (DPPs) are of interest because they are considered to be models for the retinyl polyenes that are related to vitamin A and the visual pigments. C13 substitution has a large effect on the photophysics of β-carotene. This work concerns the C13 effect on photochemistry and photophysics of 1,4-diphenyl-1,3-butadiene (DPB). We are synthesizing trans,trans-1,4-diphenyl-1,3-butadiene-1-13C (tt-DPB-C13) in order to compare its photochemistry and photophysics. to that of ordinary tt-DPB. Specifically, processes that will be compared are the efficiencies of photoisomerization to ct-DPB isomer under direct and triplet sensitized excitation conditions, the fluorescence quantum yield and the excited state lifetimes. The importance of kinetic isotope and nuclear hyperfine effects will be evaluated.
