Flavonoid derivative with extended cinnamic acid moiety was synthesized using Baker-Venkataraman reaction. The compound shows interesting UV absorption properties which make it a good UVA absorber. A bathochromic shift of 18 nm was observed when the size of cinnamic acid segment was increased by one styrylogous extension.
