Excited States of Thio-2′-deoxyuridine Bearing an Extended π-Conjugated System: 3′,5′-Di-O-acetyl-5-phenylethynyl-4-thio-2′-deoxyuridine

A new thio-2′-deoxyuridine with an extended π-conjugated group was successfully synthesized: 3′,5′-di-O-acetyl-5-phenylethynyl-4-thio-2′-deoxyuridine. The thio-2′-deoxyuridine derivative has a larg...
